OPERATION
Commercial kitchen ventilation hoods are intended to be used in conjunction with ductwork and fans,
which have been properly sized and properly installed in accordance with manufacturer's specifications
and local code requirements.
Before turning on cooking equipment; make sure that the make-up air and exhaust fans are on. Leave
fans on for at least 30 minutes after cooking equipment is shut off.
Clean hood as needed to comply with local code requirements and as directed in the Maintenance
section of this manual.
Performance Evaluation
A performance evaluation of the system can be performed only after all of the following items have been
verified:
1. All fans are operational and rotations visually verified by observation of the arrows stamped on
them.
2. All filters are in place.
3. Equipment under the hood is in place and operational.
4. HVAC units are in place and operational with blowers operating correctly.
Guidelines before Beginning
The testing and balancing of a system is necessaryto ensure proper and efficient -operation of the system
as it was designed. In any building where effluent and hot air is removed, the mass of air must be
replaced to maintain a constant pressure in the space. Any change in the pressure differential between
inside and outside air will in some way affect the operation of a system; most commonly that.affect is a
negative one.
A test and balance, as well as the simple performance test in International Mechanical Code Section
507.16.1 should be.included in all jobs; code inspectors are increasingly enforcing these requirements.
Requirements in the 20'06 IMC, which is currently effective in most parts of the United States, are as
follows:
"507.16 Performance test. A performance test shall be conducted upon completion and before
Final approval of the installation of a ventilation system serving commercial cooking appliances.
The test shall verify the rate of exhaust airflow required by Section 507.13, makeup airflow
required by Section 508, and proper operation as specified in this chapter. The permit holder shall
furnish the necessary test equipment and devices required to perform the tests.
507.16.1 Capture and containment test. The permit holder shall verify capture and containment
performance of the exhaust system. This field test shall be conducted with all appliances under
the hood at operating temperatures, with all sources of outdoor air providing makeup air for the
hood operating and with all sources of recirculated air providing conditioning for the space in
which the hood is operating. Capture and containment shall be verified visually by observing
smoke or steam produced by actual or simulated cooking, such as with smoke candles, smoke
puffers, etc."
The simplest means of doing the performance test is using a T -T puffer from www.evhill.com. Activate the
puffer and use it to trace effluent around the entire perimeter of the hood, emitting smoke every few
inches under the lower edges of the hood.

Calculating Make-up Air CFM with -a Shortridge Instrument and Spreadsheet
1. Use the Velgrid mode of the Shortridge instrument to measure supply.air velocity. Make sure to
take measurements every twelve (12) inches along the -length of the PSP.
2. Locate the appropriate Excel spreadsheet for the PSP/Supply velocity and record all necessary
'data. This spreadsheet will calculate the total supply CFM for the hood.
3. The spreadsheet is located on the manufacturer's website.
Calculating Make-up Air CFM without a Shortridge Instrument
1. Compute the open area of the supply plenum of the hood. This area. must be calculated at the
same plane that velocity readings are taken. Area can be calculated using the following formula:
Area (ft2) = Length (ft) x Width (ft)
If both the length and width are measured in inches, use the following formula:
Area (ft2) = Length (in) x Width (in) / 144
2. Record velocity of air through supply openings from,left to right on raw. data sheet.
3. Compute and record average velocity through supply. openings.
4. Compute and record CFM through supply openings.
CFM = Free area x Average Velocity
5. Compute total CFM through all supply openings for -each hood.
Calculating Exhaust Air CFM with a Shortridge Instrument and Spreadsheet
1. Use the Velgrid mode of the Shortridge instrument to measure the velocity at each'filter. .
2. Locate the appropriate Excel spreadsheet for the exhaust velocity and record all necessary data.
This spreadsheet will calculate the total exhaust CFM for the, hood.
Calculating Exhaust CFM without a Shortridge Instrument
1. Record filter sizes of each hood on raw data sheet.
2. Compute free area of the,filters.
Examples:
16"x16" = 1404 = 1.36 ft2
10"x20" = 8x18 = 1.00 ft2
12"x16"= 10x14=0.97 ft2
3. Record'velocity of exhaust gases through filters starting top left to right (5 reading/ filter)..
4. Find average velocity through each filter.
5. Compute CFM throughteach filter.
CFM = Free area x Average Velocity
6. Total the exhaust CFMforeach hood.
7. Multiply total exhaust CFM x 0.78 (this is the K factor necessary when using the EDRA
velometer).
34
External Factors which may affect Hood Performance
1. HVAC units are generally specified to supply 25% outside air (OA) to the room ventilation. If
RTU's are not supplying the proper amount of OA to thebuilding; then negative pressure will
exist.
2. HVAC return grilles located close to a hood can -cause performance. problems. The return -grille
competes with the hood to capture air -in the -room. For. example, a,return•grille fora 10-ton,°HVAC
unit can draw anywhere from 3000ito 4000 CFM. This is equivalent:to the exhaust -of a 10' to 1'3'
canopy hood. As a result; a. return air. grillelocated within>six feet,(6')-of,the,,hoodicamhave-a
serious effect on the capture ability of the hood.
3. HVAC diffusers located near a hood can create flows-in'the room that -detract -from the. capture
ability of the hood. If the HVAC diffuser bounces -.air off the -front of the- hood or directs air along
the hood and past the end, the air flow created can draw smoke and contaminants out:of the
hood.
Using a Shortridge Instrument
The Shortridge is a sophisticated instrument that, with its built-in features,-is-basically:a self-contained test
and balance kit. It has a "velocity grid" for filter face readings, a "velocity probe" for ductwork readings, a
"differential pressure" function to check room pressure and static pressure, as well:as a "temperature
probe" so it can calculate accurate values: based. on varying temperature (most•equipment -assumes
standard temperature and pressure), and many other useful features.
Hood Information
To calculate the CFM, the following information must first be acquired:
1. Hood size and length
2. Filter size and length
3. PSP width and length
Measuring Hood Static and Room Pressure
Static Pressure:
1. Measure hood static pressure at exhaust collar using the Shortridge instrument.
Static Pressure =
Room Pressure:
For an exhaust hood to work properly, the kitchen should be at a slight negative pressure to the dining
area (caused by its air removal) and the building overall.slightly positive. The dining room should be a
slight positive to the outdoors and the kitchen +0.02" w.c. or about 300 CFM positive. This will keep dust
and bugs outside and doors will be easy to open. The kitchen should be 'a slight negative to the dining
room to keep the odors in the kitchen. The kitchen should be balanced to slightly negative, 0" to -0.02"
w.c., to the dining room. Generally, if there is not enough negative, or if there is positive pressure there
will be smoke roll out from the hood that occurs due to the wind currents from people moving around in
the area, while if there is too much negative, there becomes a pressure problem on the-building(opening
doors, drafts, hot water heaters, etc.)
1. Measure room static pressure using the Shortridge instrument. Adjust the supply fan to set room
to 0.02" negative to dining area.
Room Pressure =

Adjustments
1. A hood with multiple risers should be balanced according to the cooking load beneath it. For
example, if a hood with multiple risers has a charbroiler in the center and several ovens on the
=ends, the risers should be evenly balanced. This will achieve the most efficient contaminant
capture.
2. Perforated supply plenums discharging air around the.hood should be set to the designed
discharge velocity.
3. .When fan pulleys are adjusted, belts�should then -be re -checked for correct'tension and an
amperage reading should be taken on the motor to make certain it is not overloaded.
4. The prime objective of balancing is to ensure that each hood will capture all the contaminants
produced by the equipment it covers without causing undesirable conditions in the kitchen (i.e.
excessive negative pressure, excessive quantities of hot or cold air,in the kitchen, etc.)
If problems occur, then refer to the Troubleshooting Section of this manual.
Conclusion
1. Compare specified data to the data recorded. Adjust exhaust as necessary using adjustable
pulley on fan.'Adjust supply.as necessary using dampers on supply risers and adjustable pulley
on supply fan.
2. After setting hoods to specified data, the room parameters should be checked.
3. If room parameters are not acceptable yet, the hood can be modified to improve them without
decreasing hood performance. This is an acceptable condition.
4. Use a smoke bomb to verify. that the hood captures adequately. This can be your final verification.

The following is a step-by-step procedure for installation of end-to-end ventilation hoods. Refer to
Figures 4 and 5.
1. Follow steps 1 through 10 of the Installation of a Single Hood section for each hood.
2. Adjust tension on hanging rods to position hoods so they fit flush with each other as shown in
Figure 4.
3. Bolt the top of the hoods together. See Figure 5.
4. Once all of the hoods are hung, follow steps 11 through 19 of the Installation of a Single Hood
section.
5. NOTE: Hoods having more than a 1/8" gap between them must be repositioned so that gap
between hoods is <= 1/8". Run a bead >=1/8" of silicone sealant along the lower horizontal seam
of the two hoods. Slip the U -channel trim, if applicable, over the seam as shown in Figure 4.
Tape can be used to hold the U -channel in place until the silicone cures. U -channel is not
required on hoods with Flanged ends.
6. Run a bead of the same silicone sealant along the front vertical seam between the two hoods.
Slip the T -strip trim between the hoods if applicable. See Figure 5. T Strip is not required on
hoods with flanged ends and fully welded, ground, and polished comers.
7. Proceed with steps 20 through 23 of the Installation of a Single Hood section.

Installation of a Single Hood (Wall or Island)
The following is a step-by-step procedure fog installation of the ventilation hood.
1. Uncrate the hood, being verycareful not.to.dent or scratch the outer surface. NOTE: Report any
damage to the delivering.freight.carrierand file a.clairn if appropriate. Refer to.the
installation drawing fortypical detailslof the ventilation system prior to hanging the hood. Check
the nameplate on the equipment to make; certain -it meets'the specificationsprovided by the
architect and/or engineer. If�discrepancies-.exist,. notify the manufacturer immediately.
The nameplate will also give-information•regarding .the following:
• Clearance from cooking,surface to front;Iower-edge of -the hood
• Minimum exhaust air flow
• Maximum.supply:air flow-.(if:applicable)
• Minimum front overhang from cooking: surface
• Minimum side -overhang from cookingisurface
• Maximum cooking•surface,temperature
• Replacing fusible links -for exhaust-and°supply damper(if.applicable)
• Replacing*filters
2. Determine the•height)atiwhich•the'�hood„will-Ue'•ihung:
Canopy hoods are typically.hung'-so'lthat-the�front;lowertedgp�of,.the•hood is•within•6'6'•- 7'0”
AFF: However; the hood should be, hung so.that thetproper,clearance-from the'cooking•surface
to the front lower edge of the hood is maintained. See- nameplate, forclearance-from:cooking
surface.to front lower, edge offh'oods: Exact hood hanging height- should be verified with1ocal
authorities having jurisdiction.
Note: If there are wrappers (enclosure.panels) with the,order, measure down from the.ceilingthe
height of the wrappers. That.will be the top hanging height of the hood:as longus the following
criteria are met:
•'The -front lower edge of the hood is within 6'6" to 7'0" AFF,
• The front lower edge of the hood is within the clearance requirement from the
cooking surfaces, and
• If the hanging height based on wrappers does not fall in this range, contact your local
office.
Backshelf hoods are typically hung at the maximum height allowed from the cooking surfaces.
See nameplate for clearance from cooking surface to front lower edge of hood. Exact hood
hanging should be verified with local authorities having jurisdiction.
Note: If there are wrappers with the order, measure down from the ceiling the height of the
wrappers. That will be the top hanging height of the hood as long as the front lower edge of the,
hood is within the clearance requirement from the cooking surfaces. If the hanging height based
on wrappers does not fall in this range, contact your local office.
3. If the hood has a back return, install it now. See the Installation of Hood Accessories section.
4. If the hood has a bolt -together standoff, install it now. See the Installation of Hood Accessories
section.
5. If the hood has duct thermostats, install them now per the thermostat installation drawing.
6. Position hood on the floor in its approximate final position with the supply and exhaust risers on
the hood located directly beneath the corresponding openings in the roof, if possible. It is
advisable to finalize the location using. a plumb -bob or laser. Protect the hood when it is on the
jacks to avoid dents, scratches, and other damage to the hood.
7. Proceed to weld exhaust duct to hood while on the floor, if possible.
7
8. Use 1/2" threaded rod to hang hoods. Drill 9/16" holes in the structural support system or use
UnistrutO to line up with the welded-on angle mounting brackets on the hood. There are several
types of mounting brackets depending upon the hood type; each, however, has.a predrilled hole.
See Figure 2 for details. The structural integrity of the structural' support system•is the
responsibility of the contractor and the structural engineer. There are also center hanging
angles on`hoods 12 feet in length and longer. Center hanging angles must be used to
.support the hood weight and prevent filter fit and grease drainage problems. Some
backshelf hoods do not have hanging angles and must be anchored to back wall using the
standing flan'be provided. Structural lagbolts must be used every 12 inches on center maximum
and must be secured to studs behind wall.
9. The spacing on the hole for the modified support should line up with the mounting bracket on top
of the hood. The top hanger should be 1/2" closer to the back wall than the mounting bracket on
the hood to pull the hood against the wall. See Figure 3. Some hoods are designed for island
installations where a wall is not present.
10. With the hood well protected against possible scratching, raise the hood into°position using high
lifts or equipment jacks at each end to keep the hood level. When the hood is elevated to the
proper height, install 1/2" threaded rod between each mounting bracket on the' hood and the
modified support. Secure rods with heavy duty nuts and appropriately sized fender washers
above and belowthe hanging angle.
11. Make final adjustments as needed to ensure the hood is hung level.. Maintain tension on all rods
to ensure the hood weight is evenly distributed. If it is necessary to stand or work on top of the
hood, use pieces of plywood to evenly distribute weight on the hood so no damage occurs.
12. Brace hood to ceiling joists and wall(s), as applicable, so that the hood does not move. Secure
,hood, to wall in a. manner acceptable to the authority.having jurisdiction.
13.".If,the hood has Back and/or Side Perforated Supply Plenums (i.e. PSPs),.install them now. See
the Installation of Hood Accessories. section.
14.Af an AC-P.,SP•is,:to be installed with the hood, install it now. See the Installation of Hood
Accessories section.
15. Install the. exhaust,.-ductwork. The entire exhaust duct system must be continuously welded, liquid
tight unless it is Listed Factory Built Grease Duct. The duct must be welded to the hood exhaust
collar and the roof curb cap must be welded to the exhaust duct. See Guidelines. for Ductwork
Installation - By Others.
16. Install the supply ductwork. See Guidelines for Ductwork Installation;- By Others.
17. If the hood is equipped with.a control unit, an installation wiring diagram will be provided inside of
the control unit. The jobsite electrician is responsible for making the appropriate field
connections. This includes all lights and duct/hood mounted thermostats.
18. If the hood is equipped with a factory prepiped fire` suppression system, a certified fire system
.installer is responsible for completing the field hookup, testing, and certifying the system in
accordance with the manufacturer's specifications and the local fire codes. If the hood is not
prepiped, a certified fire system installer is responsible for installing, testing and certifying the
system in accordance with the manufacturer's specifications and the:local fire codes.
19. If the hood is equipped with wrappers (enclosure panels), end panels, and/or backsplash panels,
install them now. 'See the- Installation of Hood Accessories section.
20. Caulk the lower edge of the hood where it meets the wall. This does not apply to hoods installed
in island configurations.
21. Install light bulbs, light globes, and grease filters in the hood.
22. Install grease cups in the brackets/slots provided.
23. Use a stairile'ss'steel polish to clean the hood of dust or dirt acquiredin transit.
24. It is recommended that the protective plastic sheeting remain on the installed hood until
construction is complete, so as to avoid any damage to the equipment.
WARNING: NEVER, PUNCTURE THE HOOD GREASE CONTAINMENT AREA TO
HANG HOOD OR TO HANG ITEMS FROM HOOD. PUNCTURING THE GREASE
CONTAINMENT AREA WILL VOID WARRANTY AND LISTING ON HOOD.

It is imperative that this unit is installed and operated with the designed airflow, filters"an'd construction in r
r
-accordance with this manual. ' If there are any questions about any items, please call the service ^
" department at 1-866-784-6900 for warranty and technical support issues.
y, WARNING: IMPROPER INSTALLATION; ADJUSTMENT, ALTERATION, SERVICE
OR MAINTAINANCE CAN CAUSE PROPERTY 'DAMAGE;• INJURY OR DEATH.
READ'THE INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
THOROUGHLY BEFORE INSTALLING OR SERVICING THIS EQUIPMENT.
Site Preparation
` 1. Provide clearance around installation site to safely rig and lift equipment into its final position. `
Consider general service and installation space when locating unit.
2. Locate unit close to the space it will serve to reduce long, twisted duct runs.
3. Thoroughly review the plans and specifications of the project. '
4. Determine the exact location in which the cooking hood will be installed and verify that there are
no interferences which will prevent proper installation.
y 5. Verify that all overhead beams and angles are structurally strong enough to support the -weight of
the hood and hanging system.' It is often necessary to strengthen existing structural beams, as
they are not designed to carry the weight of a stainless steel hood. Refer to the project submittal
drawing for hood weight(s). It may also be necessary to create a support structure suspended
from the ceiling joists to better align with`the desired hood location. ,.
6. Determine if adequate room is available to install the hood and all ductwork with proper
r" clearances from combustible material. IMC, NFPA96 and local authorities having jurisdiction call
' for a minimum clearance (typically 18 inches for type 1, grease rated hoods) between the cooking
liood(s), exhaust ducts, and building materials which are combustible. However, IMC and
NFPA96 outline acceptable clearance reduction methods; most authorities accept the
clearance reduction methods approved in the manufacturer's ETL listing for Type 1, ,
grease rated hoods. See Figure 1. It is important to check with the local authority having
jurisdiction to determine that the installation method is satisfactory to meet their requirements
prior to installing the equipment. .

LISTINGS
This grease duct is ETL listed to standard UL -1978 when installed in accordance with these installation
instructions and National Fire Protection Association Standard "NFPA 96, Standard for Ventilation Control
and Fire Protection of Commercial Cooking Operations".
APPLICATION
The listed grease duct is suitable for use in commercial cooking installations for the removal of smoke and
grease laden vapors. The grease•duct system includes all components fora complete exhaust system
from the hood to the exhaust fan inlet.
Grease duct installations require provisions for cleaning the interior of the duct. NFPA 96 cleanout
requirements are as follows:
1. A cleariout must be provided at each change of direction except where the entire length of duct can
be inspected and cleaned from either the hood or the discharge end.
2. On. horizontal duct runs, at least one (1) 20" diameter opening must be.provided: Where the
opening is smaller than 20" diameter, openings large enough to permit cleaning; must be provided
atintervals of no more than 12'.
3. Openings must be at the side or the top, whichever is moreaccessible. "When the opening is on
the side of the duct, the lower edge of the opening must be at least 1 '/2" above the bottom of the
duct. For the listed grease duct, this is accomplished by the use of the grease manifold tee and
cleanout cap.
4. On vertical duct runs where personnel entry is possible, access must be from the top of the riser.
Where entry is not possible, access must be provided at each. floor.
NOTE: ACCESS REQUIREMENTS ARE SUBJECT TO CHANGE IN ACCORDANCE WITH LOCAL
CODE. LOCAL AUTHORITIES SHOULD BE CONSULTED FOR EXACT REQUIRMENTS. GREASE
DUCT MAY BE CONNECTED ONLY TO HOODS IN A SINGLE FIRE ZONE ON ONE FLOOR. DO NOT
CONNECT GREASE DUCTS TO ANY OTHER PART OF THE BUILDING VENTILATION OR EXHAUST
SYSTEM.
When grease duct is installed in accordance with these installation instructions and the joints are sealed
properly with the recommended sealant, the system will contain a grease fire within the duct. A grease fire
can burn at extremely high temperatures. This system should be dismantled and inspected after any
exposure to a grease fire. Any section that is distorted or discolored should be replaced. All joints in the
system should be examined. Because the sealant expands to assure a positive seal in the case of a fire,
any sealant that has been exposed to high temperature must be replaced. This will ensure that the system
maintains its integrity against fire conditions in the future. The manufacturer of this grease duct can not be
responsible for grease duct systems that are not properly maintained or have been subjected to one or
more grease fires.
Grease duct systems size and capacity information may be obtained from the "ASHRAE Handbook —
Fundamentals" or from the "Air Pollution Engineering Manual" of the "US Environmental Protection Agency".
Refer to the grease duct systems catalog for descriptions and dimensional data of parts.

Collar & Adjustable Duct Connections
The collar and the adjustable length duct have two major functions:
(1) Make up odd lengths of duct as needed in short runs as in
termination of the duct at the exhaust fan. (2) Serve as an expansion
joint for thermal expansion in larger runs of duct.
When used in systems of any orientation, it can perform both
functions simultaneously. The adjustable duct section is overlapped
to allow ,grease to drain back to the hood in both vertical and
horizontal installations See Fig.10. The adjustable duct is flanged at
one.end only. The collar is constructed of the same material as the
duct, and is also designed with a'/" flange that,is connected td"the
standard duct section using the joint assembly method listed above
See Fig.1. Collars are also sealed using high temperature silicone
that compresses around the adjustable duct when the - collar
hardware is tightened. The collar is designed to securely hold.the
adjustable duct, while allowing for thermal expansion.

"V" clamp min overlap
Main
When the adjustable length duct and collar are installed in the vertical position between two fixed points, such
as the beginning support and the ending support, it should:be installed just below the higher support. To ensure
proper axial alignment, wall guide support assemblies must be installed below the duct joint immediately below
the adjustable duct. This combination of parts will force -the sliding inner and outer parts of the adjustable duct
to overcome collar friction allowing movement along the axis of the duct and thus relieving expansion stresses
which would otherwise develop between the fixed points of the heated
vertical duct.
1. Slide the adjustable collar over the adjustable 'duct. Flanges
should be opposite.
2. Slide -the adjustable duct into the standard duct to the point that
the collar flange and the standard duct flange meet.
3. The adjustable collar and standard duct are joined and sealed
using -the method listed above in Fig.1.
4. Slide the adjustable duct into the standard duct to the desired
length. The minimum overlap dimension depends on the duct
diameter. See Table 2. for proper overlap dimensions.
5. The collar is sealed to duct using high temperature silicone.
6. Once the desired overlap has been met, tighten the '/4-20
hardware on the "V" clamp and the outside of the adjustable
collar between 40 - 60 in -lbs.
7. Inspect the connection for gaps in silicone.

Risers — Factory & Field. (Bolted & Welded) Risers
There are two options for the riser (connection.to;hood plenum); Factory welded and field welded or. bolted.
Dimensional "data identifying the size and location of the riser must be provided for factory installation. The
riser is fully welded to the hood plenum.
When field installed, the riser is shipped loose allowing the installer at the jobsite to decide on the final"location
of the riser. Field installed risers help when";the final location is not known or adjustments may have to be
made due to duct misalignments. Field install ed. risers may be welded or bolted in. place.
1. Bolted risers come with two rings that are used forthe connection to the hood plenum, one is connected
to the riser and one will.be loose.
2. Locate the desired position" of the riser on the top of the hood. Use the riser as a guide when -marking
the top of the hood. Make sure that the hole location is inside the plenum area before. cutting.
3. Since the riser is going to be bolted on, a bolt hole circle is required. Use the loose ring as a guide.
4. Use the high temperature silicone provided to seal above and below the cut hole, there should be no
gaps in the silicone either around the cut hole or the bolt hole circle.
5. Center the riser over the cut hole and push down into the silicone. The silicone should. be visibly
coming through the bolt hole circle on the riser ring.
6. Align the loose riser ring over the hole on the inside of the plenum and push into the silicone. Align
with the riser ring above the hood and bolt the two rings together using'/4-20 hardware.
7. Excess silicone should be removed, and .the connection should be inspected for gaps and loose
hardware.
8. When joining standard duct to the riser use the method shown in Fig. 1 — JOINT ASSEMBLY.

Duct Drains 1 : -
Drains are used to provide a point at which low points in the duct system can be Fig. 4 — Duct Drain
drained. Condensation and low lying water left over from duct cleaning can be
drained easily with Ahe installation of the ball valve drain. Drains. are designed to , .
aid in duct.cleaning and can. be used to.drain grease into:an.approv"ed,grease Tee
collection reservoir. Drains can be hard piped to an approved.grease collection
reservoir, remove the cap and connect to the 1-1/2" NPT,threads. See Fig. 4. for Adapter
details.
Grease Manifold Tee
The grease manifold tee is used to provide access for cleanout to comply with NFPA
96 requirements. It is equipped with an internal blank that acts as a grease dam
and gasket. The access port is then closed with a cleanout cap or tee cap. The
location of the access port in the tee is dependent on the orientation of the tee in Drain
the final installation. Access port location is coded as Position 1, 2, 3, 4 see Fig. 5.
Access ports are never located where grease can build up and fall out once the
i
cleanout cap is removed.

Access Door (Tee Cap) Assembly
Access doors (tee caps) are available 8" to 24". They work in conjunction with the manifold tee as previously
shown in Fig. 5. The tee joint connection is shown in Fig. 1 — JOINT ASSEMBLY; however, the installation
of the access door is slightly different so read the following instructions very carefully. Consult NFPA 96,
Chapter 7, Section 7.3.1 'Openings shall be provided at the sides or at the top of the duct, whichever is more
accessible, and at change of directions".
1. Select the location and the position of the access door.
2. All tee joints will be connected as shown in Fig. 1 — JOINT ASSEMBLY except for the access door.
3. Apply the proper sealant to the flange of the tee that will be used for access to the duct system.
4. Apply a'/4" continuous bead around the flange.
5. Center the inside blank (grease dam) over the opening of the tee and apply pressure. Pushing the
inside blank down onto the tee flange sealant, securing the inside blank to the tee flange.
6. Apply enough pressure to create a positive bond between the tee flange and the inside blank. Remove
excess sealant after making parts concentric (centered).
7. Apply a Y4".,continuous bead around the inside blank 1" from the outside edge.
8. Center the listed gasket over the inside blaWand push the gasket down into the sealant --securing th"e
gasket to the inside blank.
9. Sealant will begin to cure upon exposure to atmospheric humidity. It will form a flexible seal.
10. Once the sealant is dry attach the access door using a "V" clamp. 'Ensure flanges are in the °V" before
tightening Y4-20 hardware between 40 - 60 in -lbs.

Fan Adapter Plate
The fan adapter plate (Transition Plate) is designed to
connect to a roof curb. The duct section is welded to
the underside of the adapter plate. The adapter plate
is formed to provide a slope to allow grease deposits
to flow back towards the duct. When connected, see
Fig. 7, the plate mounts on top of the fan curb, which
supports the fan housing. The plate may be positioned
off center within the curb provided that the minimum
distance to combustibles is maintained. In the event
that the plate is positioned off center, trim off excess
plate material to allow forfan placement. Secure the
plate to the curb using a minimum of three fasteners
per side. A suitably sized fastener provided by others
is used. The fan adapter plate can be used to maintain
distance to combustibles and also for vertical support.

Duct systems serving Type 1 hoodsshall be constructed and installed so that grease cannot collect in any
portion of`the duct system. The.duct.system shall slope not less than 1/16" per linear foot towards the hood or
toward an approved grease collection reservoir. Where horizontal ducts exceed 75 feet in length, the slope
shall not be less than 3/16" per linearfoot. Offset collars have been designed to meet the above specification.
The collar is used in conjunction with other accessories such as tee's and elbows to maintain the above listed
slope in horizontal duct runs. The W" clamp hardware should be located on the top side of the duct and. be
orientated between the 3 and 9 o'clock position on the duct. Never install the "W clamp with the hardware
orientated on the bottom side of the duct on horizontal runs.
Alignment & Bracing of Grease Duct
Grease duct has the characteristics ofa continuous stainless steel pipe and -it will expand and contract along
its entire length with changes in its temperature. For this reason, conventional methods of attaching guides
and braces to the outer wall of the grease duct cannot be used. Correctly installed.support rings, saddles and
wall guide assemblies will serve to keep'the.duct aligned, provide for adequate resistance to lateral loads and
allow the free axial expansion and contraction movement. A simplified rule for duct expansion is that the axial
growth will be approximately 1 inch per 100 feet of pipe length for each 100 degrees Fahrenheit the exhaust
vapor temperature is above the surrounding air temperature.
Horizontal Support & Support Spacing
Table 3 — Horizontal Support Spacing
Horizontal duct runs are supported using either 2 X 2 X 1/8" angle or
Unistrut, horizontal support spacing is shown in Table 3. When cutting
the angle or Unistrut to length there must be a minimum of 2" on either
side of the duct or duct wrap. Its important that the 3/8" threaded rod
suspending the angle or Unistrut does not rub against the duct or duct
wrap. Once the angle has been cut to length it is suspended using 3/8"
threaded rod (minimum). Appropriate sized holes are drilled/punched
in either end of the angle. The 3/8" threaded rod is secured to the angle
or Unistrut using appropriate sized hardware, washers are used on the
top and bottom before installing nuts, double nuts are used to make sure
bottom nuts do not come loose, see Fig. 8.

The wall guide is to be'attached.tot Non -Combustible and Combustible surfaces. The wall guide, is
constricted of 12 gauge steel and is comprised of a full ring,, brackets, angle struts, wall support plates and
hardware for assembly (includes mounting hardware to secure supports to gypsum walls constructed using 25
gauge steel studs), see Fig. 9. The ring, which is split in two halves for ease. of assembly, is constructed of 12
gauge steel. With.th"e addition of.a'spacer between the two halves., the diameter is 1/8" larger than the outside
diameter of the duct. ihis.is to allow for thermal expansion.
The wall support should be installed at the joint of the duct'and below thi! "V" clamp so the "V" clamp moves
away from the support ring. The wall guide assembly is designed for 2 to. 1.8 inches clearance from duct to
non-combustible / combustible walls. The side struts may be placed eitherup or down as is convenient. This
assembly.is intended to resist lateral or side loads only, and,is not for carrying the weight of,the•vertical grease

CLEARANCES
This grease duct is primarily intended for use in non-combustible surroundings, -when installed in a room where
enclosure is not required. Grease duct may be located at clearance to combustibles in accordance with Table
5. Grease duct may be located in a corner formed by -two combustible walls provided the minimum clearance
is maintained.
In all buildings more than one story in height and in buildings where the roof -ceiling assembly is required to
have a fire resistance rating, the duct must be enclosed in a continuous enclosure from the lowest fire -rated
ceiling or floor above the hood, through any concealed spaces, to or through the roof to maintain the integrity
of the fire separations. required by the applicable building code provisions. If the building -is lless than 4 stories
in height, the enclosure shall have afire resistance rating of not less than 1 hour. If'the•building is 4•stories or
more in height, the enclosure shall have afire resistance rating of not less -than 2 hours. The clearance
between the outside of the duct and the inside of the rated enclosure must be a minimum* of 6.inches or required
by code.

Zero Clearances to Combustibles
This duct is to be used in non-combustible surroundings. Where the duct does not require an enclosure, it
must have a minimum clearance to adjacent combustible walls as shown above in Table 5 — CLEARANCES.
In cases where the ducting extends through any story of a building above the location at the connected
appliances, it must be enclosed in the upper stories with walls having a fire resistance rating of not less than
one hour for buildings of two or three stones in height. If the building is four stories or more in height, the
enclosure wall shall have a fire resistance rating of not less than two hours.
METHODS USED TO TEST DUCT.AFTER ASSEMBLY
Prior to the concealment of any portion of a grease duct system; a leakage test shall be performed. in the
presence of,the code official. Duct shall be considered to be concealed where installed. in shafts or covered
by coatings or wraps that prevent the ductwork from being visually inspected- on all sides. A light test or
approved equivalent test method (smoke.test) shall be performed to determine that all joints are liquid tight.
The smoke test is used for longer duct runs while the light test is used for short duct runs, both methods are
approved for use.
Method 1 — Light Test per IMC 506.3.3.1
A light test shall be performed by passing a lamp having a power rating of not less than 1 00watts through the
entire section of ductwork to be tested. The lamp shall be open so as to emit light equally in all directions
perpendicular to the duct walls. The test shall be performed for entire duct system, including the hood -to -duct
connection. The ductwork shall be permitted to be tested in sections, provided that every joint is tested.
Method 2 — Smoke Test
After the ductwork has been installed allow the listed'sealant to cure for a minimum of 24 hours. Smoke
bombs are lit and: placed at the bosom of the duct system, natural upwards!drafts will pull the smoke to the
top of the duct system. Various length duct runs may require multiple smoke bombs.. Once the smoke has
reached the top of the duct run, cap the duct, making sure it's secure. Inspect all joints for leakage.
GENERAL DUCT WEIGHT
Two different material gauges are available, 20 gauge is the minimum / 18 gauge is the maximum allowable
material per this listed duct. Both gauges have been tested by ETL and comply with standard UL -1978. 20
gauge is the standard material used in application with 18 inches or more'to combustible surfaces. 20 gauge
duct may also be wrapped using a listed duct wrap for zero clearance to combustibles, 18 gauge is required
in some JHA when duct needs to be wrapped using a listed duct wrap for zero clearance to combustibles.
Weight — 20 Gauge Duct
The following formula can be used to approximate the weight of total lengths of duct for 20 GA duct (.0327 x
"L" x "D"). "L" and "D" should•be calculated in. inches, where L is the length and•D•is the diameter. Example:
A total ;length of duct is 25 ft long,.14"diameter (.0327 x (25'x 12") x 14" = 137 LBS):
Weight —18 Gauge Duct
The following formula can be used to approximate the weight of total lengths of duct for 18 GA duct (.0417 x
"L" x "D"). "L" and "D" should be calculated in inches, where L is the length and D is the diameter. Example:
A total length of duct is 25 ft long, 14" diameter (.0417 x (25'x 12") x 14" = 175 LBS).

Figures 5 and 6.
1. Follow steps 1 through 10 of the Installation of a Single Hood section for each hood.
2. Adjust tension on hanging rods to position hoods so they fit flush with each other as shown in
Figure 6.
3. . Bolt the top of the hoods together by sliding a threaded rod through the connection bracket slots
and fastening it into position by using heavy duty nuts and washers. See Figure 5.
4. Once all of the hoods are hung, follow steps 11 through 19 of the Installation of a Single Hood
section.
5. Run a bead >=1/8" of silicone sealant on the lower horizontal seam between the two hoods. Slip
the U -channel over the seam as shown in Figure 6. Tape can be used to hold the U -channel in'
place until the silicone cures.
6. Run a bead of the same silicone sealant along the side vertical seam between the two hoods.
Slip the T -strip trim between the hoods. See Figure 5. T Strip is not required on hoods with
flanged ends and fully welded, ground, and polished comers.
7. Proceed with steps 20 through 23 of the Installation of a Single Hood section.

as a guideline only. Ductwork should be installed in accordance with the local codes and restrictions. It
is the responsibility of the installer to check local codes prior to installing the ductwork.
1. All ductwork,must,be-installed in the�most directmanner, possible.
2. Exhaust duct -must be -made of 16 gauge carbon steel, 18 gauge stainless steel or must be. listed
for: use with �commercial. kitchen.hoods and follow the manufacturer's listing.
3. , Per..NEPA-96, all�exhaust;ductseams)and joints musthave a continuous.liquid tight external
weld; exception would:be.,Listed Factory Built Grease,Duct.
4. ExhausVrisers on the,hood have been sized to achieve a -velocity of 500-2200 FPM, per.NFPA
. 96, based upon -the CFM,required`for the -hood. ' Maintain the area; of each riser when connecting
duct offsets, or transitions.
5. Branches should enter. at gradual, expansions and at atpreferred angle of 30,degrees or 45
degrees if necessary.
6. When.a "pantleg:duct" is required,.to bring two -ducts into one. exhaust -fan, observe -the following in
order to obtain desired performance:.
a. Use ONLY radius back and radius throat elbows: 2 to..2:5 diameter centerline radius is
recommended.
b.._ Maintain the,distance,between;the center lines.of.exhaust.ducts at.a maximum of 12'
apart.
c. The main duct going.to. the exhaust..fan must be. the, sum of the area of the separate legs.
7. Supply.air risers are sized.around. a maximum 600'FPM. Maintain this area when. installing
ducts.
Do not use "flexible" type duct for supply:duct. Only rigid type duct.installed in accordance with
SMACNA Low•Pressure requirements will be acceptable.
9. Access Doors should be provided at the sides or at the top of the duct, as well as changes of
direction. Please refer to your AHJ if questions on requirements for horizontal and vertical duct
run.
10. IMPORTANT: When a fusible link is installed in the make-up air damper at the hood collar, an
access door must be cut into the supply duct by the installer.
11. Duct sensor may ship loose on hoods with field cut risers. When double wall duct or ductwork
with a diameter smaller than 10" is used, loose duct sensors should be installed in the top of the
plenum near the riser in the path of the exhaust airflow.

Installation of Hood Accessories
Back Return Installation
1. Locate the assembly and unpack the product from the crate, being very careful not to dent or
scratch the outer surface. NOTE: Report any damage to the delivering freight carrier and file
a claim if appropriate.
2. If the supply risers are to be field cut, cut the risers in as desired. NOTE: For factory cut,
supply risers, the manufacturer installs Ia 2" vertical flange around the opening._ This flange
is intended to slip inside a supply boot that is provided by the installer.
3. Locate the wall and ceiling joists which will support the assembly.
4. Use 1/2" threaded rod to hang the back return.' Install the threaded`rod and angle or,Gnistrut®
that will be used to; hang the assembly from the ceiling joists.. Drill 9/16° holes as needed in the
arigie for the threaded rod. Be sure tolineup with'th'e welded -on angle mounting brackets on the
back return. -

5'. The -back return is typically Hung so=it`s top'edge is the same height as the top edge `of 66 food.
See Figure 7. Refer to Step 2 in the Installationof a Single Hood -instructions to determine'the
'hood and back return flanging Heights. '
6. .Slowly raise the back return until hanging rods can be attached to the'hanging angles. It is
advisable to 'do-this,before-the back return reaches its'final height. NOTE: Please use:caution
as weight is not proportionally dispersed. Install the threaded rod into the back'return

7.' Make sure the -back return is level. Secure to wall in" a Vmanner acceptable to the AHJ.
8. If there are multiple. back return sections, install the remaining, sections now. Use caulk and the
-`F--strip trim between adjacent b'ack1ei turn sections. see Figure 8.
9. Peel the protective plastic coating on the- back return down below where the t ottom' e'dge*of the
hood Wili're'stagainst it,'soJ does not'remain behind the hood:

Bolt -Together Standoff Installation
1. Unpack the standoff panels from the shipping container, being very careful not to dent or scratch
the panels. NOTE: Report any damage to the -delivering freight carrier and file a claim if
appropriate.
2. Mount the end caps for the back standoff to the hood securely with self -tapping sheet metal
screws. Clamp the back standoff and the hood together before screwing so they do not shift. See
Figure 9.
3. Place the back standoff filler piece into place flush with the rear bottom edge of the hood and
secure with self -tapping sheet metal screws.
4. Continue with hood installation instructions.
5. After the hood installation is complete, secure the bolt -together standoff to the wall or other hoods
as applicable in a manner acceptable to the authority having jurisdiction.

Place the back standoff horizontal filler
piece into place. Mount the filler piece
using self -tapping sheet metal screws,
provided. Screw through the filler piece
flanges into the studs on the back side of the
hood. Do not penetrate into the capture
area. Once complete, no screws should be
visible from the outside of the hood.
Attach the back standoffs to the wall using
screws appropriate for the wall. Screw
through the flanges of the standoff into the
wall. If standoff mounts against another
hood, use the procedure from steps 1 and 2
for the second hood

to the ceiling joist.
5. Use 1/2" threaded rod to hang the PSP. Install the threaded rod•and angle that will -be -used to
hang the assembly from the ceiling.joists. Drill 9/16" holes in.the angle if not=using Unistrut@. Be
sure to line up with the angle mounting brackets on the PSP.
6. Peel the protective plastic coating on the hood down below where the bottom edge of the- PSP
will rest against the hood, so it does not remain behind the PSP.
7. Move the PSP into position as indicated by the project submittal drawings; lining up the top edge
of the PSP with the top edge of the hood. Remove the protective coating from the back of the
PSP. See Figure 10.
8. Install the threaded rod into the PSP hanging angles and use heavy duty nuts to secure the
connection. Adjust tension on hanging rods to position PSP so it fits flush with the hood. NOTE:
Do not apply too much tension; otherwise, a -gap between the PSP and -Hood will be
created at the bottom.
9. Install additional PSPs, if applicable, in the same manner.
10. Where applicable, use sheet metal screws to secure the PSP attaching bracket on top of side
PSPs to front PSP. See Figure 11.
11. Caulk the seams between the hood(s) and each PSP assembly, as well as between adjacent
PSP assemblies (if applicable) after the hood(s) and hood accessories have been installed. An
