(CONT.)
EN
When properly cared for, your new Outdoor Pro Canopy has been designed to be a safe, reliable
ventilation system. Read all instructions carefully before using this ventilation system. When using
cooking appliances, basic safety precautions must be followed.
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO
PERSONS, OBSERVE THE FOLLOWING:
a) Use this ventilation system only as intended by the manufacturer. If you have any questions,
contact the manufacturer.
b) Before servicing or cleaning unit, switch power off at service panel and lock the service
disconnecting means to prevent power from being switched on accidentally. When the service
disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag,
to the service panel.
FOR GENERAL VENTILATING USE ONLY. DO NOT USE TO
EXHAUST HAZARDOUS OR EXPLOSIVE MATERIALS AND VAPORS.
TO REDUCE THE RISK OF A GREASE FIRE:
a) Never leave burners or surface units unattended at high settings. Boilovers cause smoking and
greasy spillovers that may ignite. Heat oils slowly on low or medium settings.
b) Always turn hood ON when cooking at high heat or when flambéing food (i.e. Crepes Suzette,
Cherries Jubilee, Peppercorn Beef Flambé).
c) Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
d) Use proper pan size. Always use cookware appropriate for the size of the burner or surface
element.
TO REDUCE THE RISK OF INJURY TO PERSONS, IN THE EVENT OF
A GREASE FIRE, OBSERVE THE FOLLOWING *:
a) TURN OFF ALL BURNERS. If the fire is contained in a small area, you may attempt to
SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray. For a grill, closing the lid
may not always smother the flames. BE CAREFUL TO PREVENT BURNS. If the flames do not
go out, shut off the gas supply, EVACUATE AND CALL THE FIRE DEPARTMENT.
b) NEVER PICK UP A FLAMING PAN - You may be burned.
c) DO NOT USE WATER, including wet dish cloths or towels - a violent steam explosion will result.
d) Use an extinguisher ONLY IF:
1. You have a Class ABC or Class K fire extinguisher and you already know how to operate it.
2. The fire is small and contained in the area where it started.
3. The fire department is being called.
4. You can fight the fire with your back to an exit.

CLEANING AND MAINTENANCE
CLEANING THE VENTILATION SYSTEMCLEANING THE VENTILATION SYSTEM
EN
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 CANOPYHOOD 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 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.

CLEANING AND MAINTENANCE
BLOWER WHEEL REMOVALBLOWER 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.
(CONT.)
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 INSTALLATIONBLOWER 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 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 POSITIONINGMOTOR 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.
Make sure you have the correct motor in each housing position.

CLEANING AND MAINTENANCE
• 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 page8.
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
page8.

EN
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.

DUCTING DO’S AND DON’TS
GENERAL REQUIREMENTSGENERAL REQUIREMENTS
EN
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 REQUIREMENTSBLOWER REQUIREMENTS
The dual blower unit (WM2L, used in all systems) requires 8” round duct or equivalent (50 square
inches). The single blower unit (WM1L, used in addition to the dual blower unit in 900 CFM
systems) requires 6” round duct or equivalent (28 square inches).
COMBINED DUCT SIZE AFTER A TRANSITIONCOMBINED 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 (DO’S AND DON’TS)DUCTING REQUIREMENTS (DO’S AND DON’TS)
• 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.

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 DETAILSINSTALLATION DETAILS
Read all instructions thoroughly before beginning installation. These instructions apply to Hestan
outdoor hoods, when mounted over a Hestan or Aspire grill. YOU MUST FOLLOW THE GRILL
CLEARANCES DESCRIBED IN YOUR GRILL INSTALLATION MANUAL.
EN
FOR NON-COMBUSTIBLE LOCATIONS ONLY!! This appliance is wall-mounted and must NOT
be installed on or next to unprotected combustible construction. A minimum clearance to vertical
combustible material, such as adjacent walls, is 12” [30 cm] on the sides of the appliance (see Fig. 1).
ALL construction materials in the wall immediately behind the vent and the appliance below (usually
a grill), and within the 12” [30 cm] zone must be non-combustible. As an example, if you have a
stucco or tiled surface and wood-frame construction beneath, or wood-frame walls adjacent or
behind, the wood is considered combustible, even though the vent or grill is touching the stucco or
tiled surface, which is non-combustible. In extreme circumstances, the wood could potentially get
hot enough to burn.
Similarly, if you have the hood mounted over a free-standing grill which is parked close to these
surfaces when grilling over an extended period of time, enough radiant heat could reach the wood
and potentially get hot enough to burn, in extreme circumstances.
Construction materials such as metal studs with cement board and stucco/stone surfaces are ideal for
this application.
A minimum of 5” [12.7 cm] clearance behind the grill is needed to open the hood, and to adequately
capture smoke and vapors from the cooking area.
See Fig. 1 on the next page for details.

1. Read all instructions thoroughly before beginning installation. See “DUCTING DO’S AND
DON’TS” on page10.
• 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 page18 for details.
2. When installing a wall mount range hood, it is recommended that the bottom edge of the hood
be located 30” [76.2 cm] 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.
Make sure that once the hood is mounted the motor cooling vents are
not obstructed.

Consult the connection diagrams (following) for further details on exhaust outlet placement.
Method 1: Install the duct(s) from the outside of the home down to the location of the exhaust
outlet(s) on the top of the hood or to the transition (if applicable).
• If a transition is used, install duct down to the location of the transition outlet plus 1”
[2.5 cm]. This will allow the transition to engage 1” [2.5 cm] inside of duct.
Method 2: Install the duct(s) from the outside of the home to the ceiling over the exhaust
outlet(s) on the hood. The end of the duct(s) should extend 1” [2.5 cm] below the
ceiling.
Use foil HVAC tape (not grey cloth duct tape) to seal all joints. See “VENT ACCESSORIES” on
page19 for a listing of available Hestan ducting materials.
TRANSITION HEIGHTS:TRANSITION HEIGHTS:
Single and Dual Blower (WM1L + WM2L = 900 CFM): 6” round duct will connect directly to
the top of the hood; 8” round will connect directly to the top of the hood. If using
