WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO A PERSON(S) OBSERVE THE FOLLOWING:

1. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer at the address or telephone number listed in the warranty.
2. Before servicing or cleaning the unit, switch power off at the service panel and lock 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.
3. Installation work and electrical wiring must be done by qualified personnel in accordance with all applicable codes and standards, including fire-rated construction codes and standards.
4. 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 guidelines and safety standards such as those published by the National Fire Protection Association (NFPA), the American Society for Heating,  Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.
5. This product may have sharp edges. Be careful to avoid cuts and abrasions during installation and cleaning.
6. When cutting or drilling into a wall or ceiling, do not damage electrical wiring and other hidden utilities.
7. Ducted fans must always be vented to the outdoors.
8. To reduce the risk of fire, use only steel ductwork.
9. Do not use this unit with any other solid-state speed control device.
10. Do not operate any fan with a damaged cord or plug. Discard the fan or return it to an authorized service facility for examination and/or repair.
11. GROUNDING INSTRUCTION: The appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. The appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.
    WARNING: Improper grounding can result in a risk of electric shock. Consult a qualified electrician if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded. Do not use an extension cord. If the power supply cord is too short, have a  qualified electrician install an outlet near the appliance.

TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
a) Never leave 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 the hood ON when cooking at high heat or when cooking flaming foods (i.e. Crêpes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
c) Clean ventilating fans frequently. Grease should not be allowed to accumulate on fans or filters.
d) Use proper pan size. Always use cookware appropriate for the size of the surface element.

*TO REDUCE THE RISK OF INJURY TO PERSON(S) IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING:**

1. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray, then turn off the burner. BE CAREFUL TO PREVENT BURNS. IF THE FLAMES DO NOT
   GO OUT IMMEDIATELY, EVACUATE, AND CALL THE FIRE DEPARTMENT.

2. NEVER PICK UP A FLAMING PAN – You may be burned.

3. DO NOT USE WATER, including wet dishcloths or towels – This could cause a violent steam explosion.

4. Use an extinguisher ONLY if:
   A. You know you have a Class ABC extinguisher and you know how to operate it.
   B. The fire is small and contained in the area where it started.
   C. The fire department has been called.
   D. You can fight the fire with your back to an exit.

• Based on “Kitchen Fire Safety Tips” published by NFPA.

**CAUTION**

1. For indoor use only.
2. For general ventilating use only. Do not use it to exhaust hazardous or explosive materials and vapors.
3. To avoid motor bearing damage and noisy and/or unbalanced impeller, keep drywall spray, construction dust, etc. off the power unit.
4. Your hood motor has a thermal overload which will automatically shut off the motor if it becomes overheated. The motor will restart when it will cool down. If the motor continues to shut off and restart, have the hood serviced.
5. The bottom of the hood MUST NOT BE LESS than 24” and at a maximum of 30” above the cooktop for best capture of cooking impurities.
6. Two installers are recommended because of the size of this hood.
7. To reduce the risk of fire and to properly exhaust air, be sure to duct air outside. Do not exhaust air into spaces within walls or ceilings or into attics, crawl spaces, or garages.
8. Be careful when installing the decorative flue and hood, they may have sharp edges.
9. Please read the specification label on the product for further information and requirements.

OPERATION

Always turn your hood on before you begin cooking to establish an airflow in the kitchen. Let the blower run for a few minutes to clear the air after you turn off the range.
The hood is operated using the push buttons on the front panel.

A. DELAY SWITCH
When a blower speed is selected, press this switch to activate the delay function. The delay button will illuminate to indicate this function is activated. The blower will continue to operate for 5 minutes and will stop automatically. To cancel the delay function, press the delay switch once again.
B. START / STOP / SPEED SELECTION SWITCHES
Press the switch corresponding to the desired blower speed (from 1 for low speed to 4 for high speed). The chosen switch will light. To turn off the blower, press once more on the corresponding blower speed switch; the switch light will shut off.

C. MASTER OFF / FILTER MAINTENANCE / HEAT SENTRY™ (TRIPLE FUNCTION SWITCH)
To turn off the blower and the light simultaneously, press this switch once. After 25 hours of operation, this switch will light to indicate the filters and the blower wheel(s) need to be cleaned in order to maintain the efficient operation of the unit.
The switch light will stay on until the function is reset by pressing this switch for 3 seconds. The light indicator is used for the Heat Sentry function as well.
HEAT SENTRY: When an excessively high temperature is detected, the Heat Sentry takes control over the blower and sets it on speed 3. The triple- function switch will flash. The blower will remain on until the heat condition is back to normal. It will then return to the speed previously selected.

WARNING: The Heat Sentry can start the blower even if the hood is turned off. When this situation occurs, it is impossible to turn the blower off using the push buttons. If you must stop the blower, do it from the main electrical panel.
D. LIGHT SWITCH
This switch allows three different lighting levels according to your needs. Press once for a nightlight, twice for normal or three times to obtain full intensity. To shut off the lights without turning off the blower, press once more.

MAKE-UP AIR DAMPER
The hood is compatible with Broan Make-Up Air Damper Model MD6T or Model MD8T (optional). Purchase separately. ![best WTT32I 30 inch Wall Mount Chimney Hood

• AIR DAMPER](https://manuals.plus/wp-content/uploads/2022/08/best-WTT32I-30 -inch-Wall-Mount-Chimney-Hood-AIR-DAMPER.png)

Make the connection to the Make-Up Air Damper with low voltage wiring, as shown. See Make-Up Air Damper instructions for additional information.

CLEANING & MAINTENANCE

For performance, appearance, and health reasons, clean filter, fan, and grease-laden surfaces regularly. Use only a clean cloth and mild detergent solution on stainless and painted surfaces.
Clean all-metal filters in the dishwasher using a non-phosphate detergent. Discoloration of the filter may occur if using phosphate detergents, or as a result of local water conditions – but this will not affect filter performance. This discoloration is not covered by the warranty.
Clean the non-duct recirculating filter surfaces frequently with a damp cloth and a mild detergent. DO NOT immerse filters in water or put them in the dishwasher. Change the conduct of recirculating filters every 6 months. For replacement non-duct recirculating filters – purchase S97018968 or Model AFCWTT32 (for 30” wide hood) or S97019039 or Model AFCWTT326 (for 36” and 42” wide hoods).
The motor is permanently lubricated and never needs oiling. If the motor bearings make an excessive or unusual noise, replace the blower assembly with an exact service replacement.

LIGHT BULBS
WARNING:
Bulbs may be hot. Always allow bulbs to cool down before removing them. Use (2) Halogen Bulbs (included with hood) – 120 V, 50 W, shielded halogen bulbs – MR16 with  GU10 base. (3 bulbs for 42” & 48” hoods.)

NOTE:
Suction Cup Tool
(included with hood) can be used to install and remove light bulbs. Align pins on the bulb with a large diameter opening on the socket, then push the bulb in towards the hood and rotate clockwise until firmly seated. The position of the bulb socket (depth) is adjustable and may require adjustment when: a) certain brands of bulbs are difficult to install. b) the bulb protrudes too far below the light panel.
To change the depth of bulb sockets:
– Remove screws on light panel – set screws aside
– Remove Light Panel.
– Loosen 2 Screws holding Lamp Socket Bracket to LightPanel.
– Adjust socket/bracket to the desired depth.
– Re-tighten screws securely.
– Re-attach the light panel with screws that were previously set aside.

MEASURE THE INSTALLATION

The minimum hood distance above the cooktop MUST NOT BE LESS than 24”.
A maximum of 30” above the cooktop is highly recommended for best capture of cooking impurities. Distances over 30” are at the installer and user’s discretion; providing that the ceiling height permits.

INSTALL THE DUCTWORK (Ducted Hoods Only)

1. Decide where the ductwork will run between the hood and the outside.
2. A straight, short duct run will allow the hood to perform most efficiently.
3. Long duct runs, elbows and transitions will reduce the performance of the hood. Use as few of them as possible. Larger ducting may be required for best performance with longer duct runs.
4. Install wall cap or roof cap. Connect round metal ductwork to cap and work back towards the hood location. Use duct tape to seal the joints between ductwork sections.
