Installation
NOTE: If you have a Back
Supply Plenum (BSP), this must
be installed before the hood.
Please see Page 10.
Fig. 1
For Wall/Single Island Style
Hoods, prior to installation,
check with local authorities
having jurisdiction on clearances
to combustible surfaces, etc.
Bottom
With the hood still inside its
packing crate, position the unit
beneath its installation location.
Carefully remove the packing
crate. Place some protective
material on the floor next to

Protective Material
the crate to avoid damaging the hood as it is tipped on its side; Fig. 1. Tip the hood carefully onto the
protective material. If you have filler panels, install them now; Fig. 2. If you have integral filler panels,
no additional installation is needed.
Hood Installation Overview
If a Back Supply Plenum is provided, install first. Before raising hood, insert 1/2 in. (12.7 mm) diameter
threaded rod (by others) into hanger brackets on hood top. Check the engineering drawings or UL
label located on the inside of the hood for proper hood height above finished floor. Install filler panels
if needed. Raise and hang hood from adequate roof or ceiling supports All hanger brackets must be
used and the hood must be properly supported while lifting to prevent damage or distortion to the
hood. The hood must be hung level to operate properly. After hood is secured, make the exhaust duct
connections. The fire system distributor must be contacted at this time. After the fire system has been
installed, mount the enclosures, then the supply plenums. If an Horizontal Supply Plenum is provided,
it should be installed before the enclosures. The hood and accessories are now installed. Finally, make
the electrical connections from switches to fans and complete the fire system circuits as required by
the job specification.
Filler Panel Installation Instructions
1. Uncrate the hood and lay it on the floor

Hood Hanging Height
The hood hanging height is critical, hanging the hood at the incorrect height may significantly reduce
the ability for the hood to function properly and may be in violation of codes. The hood hanging height
(typically, 78 in. (198.12 cm) above the finished floor) is given on the UL label located on the inside of
the hood on the end panel. The hood must be hung level to operate properly. The grease trough is
pitched to drain into the grease container.
Double Island Style Hoods
Before hanging the hoods, please verify the hood marks to make sure the correct hood is
hung on the correct side.
A double island hood is created by installing two wall style hoods back to back. Use the installation
procedure described on page 5 for single island hoods; install and level both hoods. After leveling,
secure the hoods together by tack-welding and/or bolting the rear mounting brackets. Caulk this joint
with NSF Approved silicone caulk (GE SCS1009 or its equivalent). The caulk is not provided.
Continuous Capture Plenum Hoods
Remove the support angles on the open end panels. (see
Fig. 3
Fig. 3) Use the installation procedure described on page
4 for single island hoods; install and level both hoods.
After leveling, secure the hoods together by tack-welding
and/or bolting the top angles. Fasten the hoods together
using u-clips and bolts, (see Fig. 4). Caulk this joint
with NSF Approved silicone caulk (GE SCS1009 or its

Exhaust Air Balancing Baffles (EABB)
This is a guide to assist in determining if multiple hoods on one fan can be balanced to have equal
static pressure. For multiple hoods on one fan to achieve their designed exhaust flow, all of the hoods
must have equal static pressure at their designed exhaust flow.
The laws of physics force the static pressure for each branch of a duct system on one fan to always be
equal. This will happen by the flow rate increasing in low static branches and decreasing in high static
branches until the static pressure is equal in all branches.
Checking for Balance
Every hood with Exhaust Air Balancing Baffles (EABB) has a range for its static pressure. The low
number in this range is given by the standard calculation for hood static. (Static that is printed with
the CAPS submittal). The maximum increase above the low number can be calculated from the duct
velocity at the low static, (also given on CAPS submittal). This is then added to the low number to get
the highest static pressure possible with an EABB.
The maximum potential increase in static is given in the graph, or can be calculated from:
2
Max. Increase = 0.00000036 x (Duct velocity)
Maximum Increase in Static Pressure for Exhaust Air Balancing Baffle
(Fully Closed)
4.5
After the range for each hood is calculated,
it should be compared to the hood with the
4
highest static pressure. If the highest hood
3.5
falls inside of the range, then the hoods can be
3
balanced with the EABB. If it is higher than the
2.5
range, the hoods cannot be balanced.

Example 1:
Hood 1:

Ps = 0.58 in. wg

3500
Duct Velocity FPM
Hood 2:
Duct Velocity = 1800 FPM
Hood 2 has the lower Ps, at 1800 FPM the maximum increase in Ps is 1.17. The range for Hood 2 is
0.44 to 1.61. Hood 1 is less than 1.61 so these hoods can be balanced.
Example 2:
Hood 3:
Hood 4:
Ps = 2.00 in. wg
Duct Velocity = 2000 FPM
Ps = 0.44 in. wg
Duct Velocity = 1500 FPM
Hood 4 has the lower Ps, at 1500 FPM the maximum increase in Ps is .81. The range for Hood 4 is 0.44
to 1.25. Hood 3 is higher than 1.25 so these hoods cannot be balanced.
Note 1: For many systems, an EABB may not be needed on the hood that has the highest static pressure. The
exception to this is if the individual ductwork has uneven static pressures.
Note 2: When sizing the fan, use the static pressure from the highest hood and sum the CFM from all the hoods.

Balancing the Kitchen Exhaust System
A. To determine the proper dining room air balance:
1. Refer to engineering drawings to determine total exhaust CFM from dining areas.
(Exhaust fans, heating and air conditioning units, restrooms, etc.)
2. Determine the total CFM of make-up air supplied to dining area.
3. Subtract #1 from #2 above. If the result is a negative number, a negative pressure is present
in the dining area. In this case, kitchen exhaust odors could be drawn from the kitchen to the
dining area. Therefore, exhaust or supply air should be adjusted to provide a slight positive
pressure in the dining area.
B. To determine proper kitchen air balance:
1. Refer to engineering drawings to determine total exhaust from the kitchen area.
(Exhaust hoods, dishwasher hoods, etc.)
2. Determine total CFM of make-up air supplied to kitchen area.
(Make-up air hoods, heating and air conditioning units, etc.)
3. Subtract #1 from #2 above. The result should be a negative number. If the result is a positive
number, a positive pressure is present in the kitchen area. Kitchen odors could be forced into
the dining area. Also, a positively balanced kitchen area can adversely affect the performance
of the exhaust hood.
Caution: According to NFPA 96, Ch. 8-3 Replacement Air: Replacement air quantity shall be adequate
to prevent negative pressures in the commercial cooking area(s) from exceeding 4.98 kPa (0.02 in.

filters as in Fig. 40. It is helpful to make brackets to keep the anemometer at the 2 in. (50 mm)
distance and parallel to the filter. Both squareness and distance are important for accuracy.

Grease-X-Tractor™ High Efficiency Filters or Grease Grabber™ Multi-Filtration System
A. Exhaust
With all the filters in place, determine the total hood exhaust
volume with a Shortridge meter as follows:
1. All cooking equipment should be on. If the hood has
internal short circuit make-up air, it should be turned off.
2. Measuring Velocities
• Set up the Shortridge meter. Leave all holes of
Velgrid open. Do NOT tape over holes that are not
over openings. The conversion factor takes this into
account.
• For 20 in. (500 mm) high filters, position the grid
as shown in Fig. 42 and 43. Average the two
measurements.
• For 16 in. (400 mm) high filters position the grid as
shown in Fig. 44.
• For 20 in. (500 mm) wide filters, position the grid over
the left and right side of the filter. Average the two
Fig. 41
measurements.
• Take velocity readings for each filter.
3. *Calculate each filter’s volumetric flow rate by summing
the flow rate of each individual filter in the hood.
4. *Calculate the total hood’s volumetric flow rate by summing
the flow rate of each individual filter in the hood.
*Note: For best accuracy multiply the velocity of each filter by its
conversion factor and sum the flow rates. Averaging the velocity
measured for all filters may cause error.

Testing Hood Air Volume
Short Circuit Hoods
A. Supply
Fig. 45
All cooking equipment should be off. The hood
exhaust should also be off.
1. Measuring Velocities
• Velocity measurements should be made
with a digital 2.75 in. (70 mm) rotating vane
anemometer or its equivalent.
• One velocity measurement should be taken
for every 8 in. (200 mm) of short circuit
opening length, starting tight against one
edge of the opening, and finishing tight
against the other edge. The anemometer
should be placed at the bottom edge of the
opening, flush with the bottom lip as shown
in Fig. 45. Both squareness and placement
are important for accuracy.
2. Calculate the average slot velocity.
3. Calculate the CFM per linear foot by dividing
the average velocity by a conversion factor of
5.52 per ft. or 1.68 per m.
4. Calculate the hoods exhaust volume by
multiplying the CFM per linear foot by the total
hood length.
Example: 4 ft. (1.22 m) short circuit hood (36 in. (.914 m) short circuit opening):

Wiring for Hood Switch Panels
The diagrams below show a typical hood switch panel remote mounted. For hood mounted switches
refer to the wiring connection decal on the cover of the junction box on the hood top.
The diagram below shows how to wire the exhaust and supply fans with a control panel to a fire
suppression contact (FSC1). When wired properly, the suppy fan will be turned off if the fire system is
activated and allow the exhaust fan to continue to operate.
The fire suppression contact (FSC1) is provided as part of the fire suppression system and is normally
mounted in the fire system control box.

Maintenance
Daily Maintenance
1. Wipe grease from exposed metal surfaces on the hood interior using a clean, dry cloth.
2. Visually inspect the filters or cartridges for grease accumulation.
3. Remove grease cup, empty contents, and replace cup.
Weekly Maintenance
1. Remove the grease filters or cartridges and wash in dishwasher or pot sink.
Note: Filters installed over heavy grease producing equipment may require more frequent
cleaning. See filter cleaning schedule.
2. Before replacing filters, clean the interior plenum surfaces of any residual grease accumulations.
Periodic Maintenance
1. Painted hood exterior surfaces should be cleaned with a mild detergent solution.
2. Stainless steel hood exterior surfaces should be cleaned with a mild detergent and then polished
with a good grade stainless steel polish to preserve the original luster.
Note: Never use abrasive cleaners or chemicals on hood surfaces. Never use chlorine based
cleaners or iron wool pads to clean the hood. They may scratch or mar the material. Always rub
with the grain of the stainless.
3. To maintain optimum performance of your hood and fan, duct cleaning should be performed as
often as the application and code requires.
4. Re-caulk the hoods with an NSF Approved silicone caulk, (GE SCS1009 or its equivalent) as
needed.
Condensate Hood Baffle Installation
1. Grasp the baffle with drain holes facing
CORRECT
down and lift into the hood. For short hoods
with only one baffle it may be necessary to
turn the baffle slightly diagonal to fit it past
the drain channel.

Note: Required washing frequency is dependent on type of cooking and quantity of food cooked.
- Remove filters from hood and place each filter in a whirlpool sink or dishwasher.
- If using a whirlpool sink, cycle for 10 minutes. Use standard dishwash soap. (4A)
- If using a dishwasher, cycle it three times to ensure all grease is removed. (4B)
- If using standard sink, cover with hot water and degreaser and soak for two hours. Rinse after soaking.
Note: For hoods with large quantities of filters, it is acceptable to wash 3 to 4 filters each day, cycling all of the filters in three days.
Note: The beads will discolor. Standard cooking will turn the beads yellow in color. Open flame cooking will cause the beads to
blacken. Neither affects the performance of the filters.
Periodic Inspection:
- Each filter may be soaked in hot soapy water for two hours once a month prior to washing if grease build-up is found.
- Inspect the filters by holding it up to a light. Light shining through more than six holes in a group indicates filter
damage.
- For filter replacement, call 1-800-337-7400

Step 5 Replace GG filters in hood. Do Step 3 in reverse order. (3C, then 3B, then 3A)
Step 6 Latch filters together by connecting the hooks to the handle on the next filter. Slide hook on from the top and bottom
of the handle. Do not try to snap the hooks into place. Do Step 2 in reverse.
Step 7 Replace the front GX filters. Do Step 1 in reverse. Be sure to install filters in the ends of the hood first, then install the
filters in the middle of the hood (1B, then 1A)
Caution: To prevent damage to filter media, do not wash second stage filters in detergents that contain
hydroxides such as sodium hydroxide or potassium hydroxide.
