CLEANING AND MAINTENANCE
CLEANING THE VENTILATION SYSTEM
Cleaning requirements depend completely on usage and environment. The more high-heat and/or
greasy cooking, the more often the hood and blower will need cleaning.
The grease tray and blower aren’t visible from the outside, so they must be removed for inspection.
After you’ve inspected the tray a few times over the course of six months or a year, you’ll be able to
set a cleaning schedule according to your usage pattern.
HOOD CANOPY
Wipe down the interior and exterior of the hood as needed with a soft cloth and warm soapy
water (liquid dish detergent is acceptable). Do not use acids, abrasives, strong detergents, solvents,
or scouring pads. Stainless steel should be treated with a quality stainless steel cleaner such as
Stainless Steel Magic®. Follow all label instructions. Do not polish across the grain or in circles.
BLOWER HOUSING AND SHIELD
To reduce the risk of personal injury, be sure the power is turned off in
the hood before removing the shield(s) and blower housing(s).
The blower captures grease by-products in the blower housing(s) and blower shield(s). The blower
shields require more frequent cleaning than the blower housing, but cooking usage determines how
often each item will need to be cleaned.
Item # Description
1Blower housing
2Blower shield
BLOWER SHIELD
The blower shields are easily removed for cleaning by pulling the blower shield(s) toward the front
of the hood.
Be careful to keep the tray level if the hood has been recently used and
the grease might still be warm.
Inspect and clean the blower shield. (Details follow)
BLOWER HOUSING
To remove the blower housing:
1. Unsnap two suitcase latches, one on each side of the housing.
2. Support the housing and pull it away from the blower base.
3. While pulling it back, gently “tip” it downward to clear the blower wheel(s).

CLEANING AND MAINTENANCE (CONT.)
BLOWER WHEEL REMOVAL
For instances where the blower wheel must be removed, follow the instructions below.
• Removing the blower wheel requires a 1/8” hex wrench. This may be obtained from your local
hardware store or tool supply.
The wheel is retained by a set screw on the side of the hub of the wheel that tightens up against a
“flat” spot on the motor shaft.
1. Locate the set screw on the side of the hub of the wheel.
2. Insert wrench through the blades of the blower wheel and into the set screw.
3. Loosen the set screw 1/2 turn counterclockwise.
If the wheel is difficult to remove, the area where the motor shaft makes contact with the
blower wheel hub may need to be sprayed with a common penetrating oil such as WD-40@.
After allowing the penetrating oil to soak for a few minutes, push the blower wheel forward
slightly, then gently pull the blower wheel off the motor shaft.
• Use caution to avoid bending or distorting the blower wheel and take care not to move or lose
the metal balancing clips that may be affixed to the wheel.
A soft bristle toothbrush with warm soapy water may be used to clean the blades, or soak the
blower wheel in warm soapy water.
BLOWER WHEEL INSTALLATION
When reinstalling the wheel onto the motor shaft, make sure the set screw makes direct contact
with the “flat spot” on the motor shaft.
1. Slide the blower wheel onto the motor shaft as far as it will go, making sure the back of the
blower wheel does not touch the motor mount screws protruding from the motor.
• If the motor is too far back, it will rub the motor mount screws, and if it is too far forward, it
will rub the inside of the blower housing.
2. Adjust the blower wheel slightly to find the correct front-to-rear location.
3. Tighten the set screw (clockwise) to lock the blower wheel in the correct position.
For hoods that have more than one blower wheel, make sure that white
blower wheels are matched up with white motor rings, and black blower
wheels are matched up with black motor rings.
The hood will not perform properly if blower wheels and motors are mismatched.
MOTOR REPLACEMENT
To reduce the risk of personal injury, turn off power to the hood at the
breaker or the circuit disconnect before attempting to remove the blower
motor.
MOTOR IDENTIFICATION AND POSITIONING
Motors are color-coded; black and white motors have different rotations and must be installed in
the correct positions.
• Housings with a single blower use a white blower and wheel.
• Housings with two blowers use a white blower on the right and black on the left.

TROUBLESHOOTING
If the hood does not perform satisfactorily, check the following:
• Do the blowers run?
• Are the blower wheels installed on the correct motors? (black wheel on black motor, white
wheel on white motor)
• Are the motor and wheel assemblies installed in the correct locations?
• Check the damper doors in hood behind/above blowers - do they move/open freely?
• Check the dampers/vents to outside - do they open freely, with no obstructions?
• Check for damaged or obstructed ductwork.
Make sure you have the correct motor in each housing position.
• If the replacement blower motor includes a blower wheel, then you can remove the motor and
wheel together. If you will re-use your existing wheel, then you may wish to remove the wheel
before removing the motor.
1. Remove the shield and blower housing as described
in “Blower Wheel Removal” on page8.
2. Use a ¼” nut driver to remove the three motor
mount screws that attach the motor to the base.
3. Gently pull the motor forward and down.
4. Disconnect the wiring harness, remove the old
motor.
• To avoid damage to the blower wheel, you may wish
to install the motor and then install the wheel onto
the motor.
5. Lift the new motor so you can connect the
wiring harness. Be sure to fully engage the electrical
connections and tighten the motor mount screws.
6. Check the blower wheel clearance and adjust as
needed, as described in “Blower Wheel Installation” on
page8.

DUCTING DO’S AND DON’TS
©2018 Hestan Commercial Corporation
10
EN
GENERAL REQUIREMENTS
Observe local codes regarding special duct requirements and placement of duct work against
combustibles.
• Using recommended transitions (see VENT ACCESSORIES) will ensure proper efficiency.
• Using recommended roof caps or wall louvers (see VENT ACCESSORIES) will ensure proper
efficiency.
• Use foil HVAC tape (not grey cloth duct tape) to seal all joints.
• The hood must be ducted to the outdoors without restrictions.
BLOWER REQUIREMENTS
The single blower unit (WM1L, used in 900 CFM systems) requires 6” round duct or equivalent
(28 square inches), and the dual blower unit (WM2L, used in all systems) requires 8” round duct or
equivalent (50 square inches).
COMBINED DUCT SIZE AFTER A TRANSITION
Single and Dual (WM1L & WM2L) combine to 10” round or equivalent 79 sq. in. using a multi-
blower transition such as AKVT6810 (Optional).
Two Duals (Two WM2Ls) combine to 12” round or equivalent 113 sq. in. using a multi-blower
transition such as AKVT8812 (Optional).
DUCTING REQUIREMENTS
• NEVER reduce the duct size. When combining ducts together, the square inch area of the outlet
duct must be equal or greater than the total square inch area of the ducts being combined.
• Only use smooth, galvanized, metal duct. Do not use flexible or corrugated duct. This type of
duct will restrict airflow and reduce performance.
• Make the duct run as short and as straight as possible with as few turns as possible.
• Avoid sharp-angled turns. Instead, use smooth, gradual turns such as adjustable elbows or 45
degree angled turns.
• For duct runs over 20 feet, increase the duct diameter by one inch for every ten feet of duct.
• When planning length, a 90 degree elbow is equivalent to 5 feet of duct.
TERMINATION REQUIREMENTS
Airflow must not be restricted at the end of the duct run.
A wall louver or roof cap is required for each duct run.
Every wall louver or roof cap must include a gravity damper to prevent back drafts.
Do not use screen wire or spring-loaded doors on wall louvers or roof caps.
Do not terminate venting into
an attic or chimney.

INSTALLATION
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO
PERSONS, OBSERVE THE FOLLOWING:
a) Installation work and electrical wiring must be done by qualified person(s) in accordance with
all applicable codes and standards, including fire-rated construction.
b) Sufficient air is needed for proper combustion and exhausting of gases through the flue
(chimney) of fuel burning equipment to prevent back drafting. Follow the heating equipment
manufacturer’s guideline and safety standards such as those published by the National Fire
Protection Association (NFPA), and the American Society for Heating, Refrigeration, and Air
Conditioning Engineers (ASHRAE) and the local code authorities.
c) When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden
utilities.
d) Ducted fans must always be vented to the outdoors.
TO REDUCE THE RISK OF FIRE, USE ONLY METAL DUCTWORK.
TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT USE THIS BLOWER WITH
ANY SOLID-STATE SPEED CONTROL DEVICE.
INSTALLATION DETAILS
1. Read all instructions thoroughly before beginning installation. Note: These instructions apply
to Hestan’s standard hoods only. Custom hoods may require additional consideration.
• See “DUCTING DO’S AND DON’TS” on page10.
• Weight and size: For safe installation, at least two people should be present to lift and hold the
hood. For larger hoods and installations with duct covers, it is advisable to have a third person
present to assist.
• Back Venting: If venting out the wall behind the vent instead of venting through the ceiling, see
“Back Venting” on page17 for particulars.
2. When installing a wall mount range hood, it is recommended that the bottom edge of the hood
be located no more than 30” above the cooking surface for optimum performance.
3. Select the appropriate installation method.
Method 1 is suitable for applications where the top of the hood
(blower outlet(s) location) is accessible after the hood is mounted
on the wall and when a Hestan duct cover will be used.
• NOTE: Since Hestan duct covers can be opened for access, they
can be installed with the hood and still permit access to connection
points. The duct cover frame requires that the hood and duct cover be
installed together.
Method 2 is suitable for applications where the top of the hood
(blower outlet(s) location) is not accessible after the hood is
mounted on the wall.
CAUTION
Make sure that once the hood is mounted the
motor cooling vents are not obstructed.
4. IF THE HOOD IS TO BE “BACK VENTED”, PROCEED DIRECTLY TO
STEP 5.

9. Mark the wall at the lower edge of the hood opening:
If using a duct cover:
a) Carefully remove the knockouts from the top four corners of the hood.
b) Remove the duct cover from its packaging and remove the mounting screws from the
base of the duct cover.
c) Place the duct cover on the top of the hood and secure it temporarily through the knock-
out openings using the mounting screws previously removed.
The front panel may be removed from the duct cover during handling to reduce weight.
Lift the hood (and duct cover assembly if used) to the location on the wall where it will be
installed.
Lightly mark the wall with a short, horizontal mark along the bottom edge of the hood.
When finished, remove the hood and duct cover assembly from the wall.
10. Find location of mounting strip:
a) On the back side of the hood, measure the distance between the bottom edge of the hood
and the top edge of the wood mounting strip.
b) Measure this distance above the horizontal mark made in Step 9 and lightly mark the wall
with a level, horizontal line.
c) Measure where the center (left to right) of the hood will be and mark the upper, horizontal
line on the wall with a short, vertical centerline.
11. Attach the mounting strip to the wall as follows:
a) Remove the screws inside the top of the back of the hood that retain the wood strip that is
recessed in the mounting channel. Note: Some retaining screws may be located behind the
blower(s).
b) Remove the wood mounting strip from the back of the hood and place the top edge of the
strip on the upper, level, horizontal line on the wall.
c) Referencing the vertical centerline from Step 10, place the mounting strip on the wall so it is
centered (left to right) in the space where the hood will be located. Mark the strip at two
or more stud locations, and drill clearance holes in the strip to prevent splitting.
d) Using proper hardware, attach the mounting strip to at least two wall studs.
Note: for 48” and larger hoods, three screws into studs are recommended.
12. FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK VENTING, PROCEED DIRECTLY
TO STEP 13.
• Note: Wall studs may interfere with back venting installations. Additional framing may be
required. It is necessary to cut duct access hole(s) in the wall prior to installing the hood.
• If using a duct cover, this step may be done with the duct cover removed from the hood. The
duct cover must still be mounted to the hood before mounting the hood to the wall.
Method 1:
Hold the hood on the mounting strip by aligning the channel at the top of the back of the
hood over the wood mounting strip on the wall.
Place the appropriate elbow(s) on top of the hood in line with the hood exhaust collar(s).
On the wall, trace around the elbow(s). Remove the hood and elbow(s) from the wall.

Cut around the outside of the traced line(s), avoiding wall studs. Install the duct from the
outside of the home to the opening in the wall. Use HVAC foil tape (not grey cloth
duct tape) to seal joints.
Proceed to step 14.
Method 2:
Using the applicable venting accessories and the connection diagrams (previous page) as a
guide. Install the duct(s) from the outside of the home to the wall so they will meet the
exhaust elbows to be used.
The end of the duct(s) should extend 1” past the ends of the elbows.
Proceed to step 14.
13. Check mount holes to wood strip, drill if needed:
Hang the hood on the mounting strip by aligning the channel at the top of the back of the hood
over the wood mounting strip on the wall.
While holding the hood in place, determine if the mounting holes in the channel at the top of
the back of hood align with the existing holes in the mounting strip. If they don’t, mark the
hole locations on the mounting strip.
Remove the hood and drill 3/32” pilot holes in the center of the marks in the wooden mounting
strip to avoid splitting.
14. Mounting the Hood:
FOR BACK VENTING APPLICATIONS ONLY. IF YOU ARE NOT BACK VENTING, PROCEED
DIRECTLY TO STEP 15.
• If using a Hestan duct cover, it must be mounted to the hood using the provided fasteners before
continuing.
Method 1:
a) Place the appropriate elbow(s) on the top of the hood. Elbow(s) should be placed with
the non-crimped end(s) on the inside the collar(s) of the exhaust outlet(s). Use HVAC
foil tape (not grey cloth duct tape) to seal joints.
b) Lift the hood up to the wall and hang the hood on the mounting strip, taking care to
properly align the duct connection(s) between the elbow(s) and the duct(s) in the wall.
c) Secure the hood to the mounting strip by installing the screws (previously removed from
the strip in Step 11) into the pilot holes drilled in Step 13. Caution must be taken to
avoid scratching the hood or ceiling.
Method 2:
a) Place the appropriate elbow(s) on the top of the hood. Elbow(s) should be placed with
the non-crimped end(s) on the inside the collar(s) of the exhaust outlet(s). Use HVAC
foil tape (not grey cloth duct tape) to seal joints.
b) Insert the electrical wire from the service panel into the electrical wire clamp on each
motor box. Tighten the wire clamp(s).
c) While securing the slack in the wire, lift the hood up to the wall and hang the hood on
the mounting strip, taking care to properly align the duct connection(s) between the
elbow(s) on the hood and the duct(s) in the wall.
d) Secure the hood to the mounting strip by installing the screws (previously removed from
the strip in Step 11) into the pilot holes drilled in Step 13.
• IF BACK VENTING, SKIP STEP 15. PROCEED DIRECTLY TO STEP 16.

15. Mounting the Hood, NON-Back Venting:
If applicable, install the transition on the insides of the exhaust collars and seal with HVAC tape
(not grey cloth duct tape).
Method 1:
Lift the hood (and duct cover, if used) up to the wall and hang the hood on the mounting
strip, taking care to properly align the duct connection(s) between the hood and the
duct in the ceiling.
Secure the hood to the mounting strip by installing the screws (previously removed from
the strip in Step 11) into the pilot holes drilled in Step 13.
Use HVAC tape (not grey cloth duct tape) to seal joints. Insert the electrical wire from the
service panel into the electrical wire clamp on each motor box.
Tighten the wire clamp(s).
Method 2:
Insert the electrical wire from the service panel into the electrical wire clamp on each motor
box. Tighten the wire clamp(s).
Cut a piece of duct for each outlet of sufficient length to meet the duct(s) in the ceiling
allowing room for the transition (if applicable).
If a transition is used, cut the duct to reach the transition outlet plus 1”. This will allow the
transition to engage 1” inside of the duct. See “Transition heights:” on page12
One end of the duct must be crimped to fit inside the duct in the ceiling. Insert the non-
crimped end over the transition or into the exhaust collar(s) on the top of the hood and
seal with HVAC tape.
While securing the slack in the wire, lift the hood up to the wall and hang the hood on the
mounting strip, taking care to properly align the duct connection(s) between the hood
and the duct in the ceiling.
Secure the hood to the mounting strip by installing the screws (previously removed from
the strip in Step 11) into the pilot holes drilled in Step 13.
16. If a Hestan duct covers is used, it should be secured to at least one stud using the nailing strips.
The duct cover front panel should then be installed.
17. WIRING CONNECTION: From inside the hood, using UL listed wire nuts, attach the “neutral”
wire(s) to the white lead(s), the “hot” wire(s) to the black lead(s), and the ground wire(s) to the
green lead(s) inside the motor box(es).
Do not operate hood without proper ground connection.
18. Install the blowers motor(s) by plugging the wiring connectors in and securing the blower
motor(s) using the retaining screws that were removed in Step 7.
19. Replace the blower housing(s) and the blower shield(s). Make sure that the damper(s) open and
close smoothly.
20. Turn power ON, verify operation: See “Using the Ventilation System” on page5 for proper
hood operation. Test all blower and light functions to ensure they are operating properly.
