INTENDED FOR DOMESTIC COOKING ONLY
IMPORTANT SAFETY INSTRUCTIONS
WARNING – TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS, 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 unit, switch power off at service panel
and lock service panel 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 a qualified
person(s) 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
backdrafting. 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.
5. When cutting or drilling into wall or ceiling, do not damage electrical
wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. Use with approved cord-connection kit only.
8. To reduce the risk of fire, use only metal ductwork.
TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
1. 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.
2. Always turn hood ON when cooking at high heat or when cooking
flaming foods.
3. Clean ventilating fans frequently. Grease should not be allowed to
accumulate on fan or filter.
4. Use proper pan size. Always use cookware appropriate for the size
of the surface element.
!
IMPORTANT SAFETY INSTRUCTIONS
1. For general ventilating use only. Do not use to exhaust hazardous or
explosive materials and vapors.
2. To reduce the risk of fire or electrical shock, this range hood should
not be used with an additional speed control device.
3. To reduce the risk of shock, disconnect power before servicing.
4. To reduce the risk of fire and to properly exhaust air, be sure to duct
air outside.
PLAN THE INSTALLATION
Recommended mounting height is 18” to 24” from the bottom of the range
hood to the top of the cooking surface.
The hood should be mounted to the bottom of a standard wall cabinet. If
the hood must be mounted directly to a wall, secure the hood to wall studs.
All wiring must comply with local codes and the unit must be properly
grounded. The hood is connected to a 110-120vAC lighting circuit (15
amp) in the circuit breaker or fuse box.
This range hood is “Convertible” – it may be installed as a ducted or as a
non-ducted unit.
IF THE RANGE HOOD IS TO BE NON-DUCTED:
• Purchase non-ducted (duct-free) charcoal filter Model BPQTF.
IF THE RANGE HOOD IS TO BE DUCTED:
• Ductwork can be installed vertically or horizontally.
• Duct runs should be as short as possible.
• Avoid the use of elbows.
• Use duct tape at all joints.
• Do not use duct smaller than the discharge on the hood.
• For 7” round ductwork installation, use 7” round damper, Model BP87
(purchased separately).
TO REDUCE THE RISK OF INJURY TO PERSONS 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 - a violent
steam explosion will result.
4. Use an extinguisher ONLY if:
A. You know you have a Class ABC extinguisher, and you already
know how to operate it.
B. The fire is small and contained in the area where it started.
C. The fire department is being called.
D. You can fight the fire with your back to an exit.

PREPARATION
1. Use the dimensional drawings (Refer to FIGURES 1 - 3) to lay
out the range hood’s mounting holes, wiring access and
ductwork by marking the cabinet bottom and drywall where
applicable.
2. Make cutouts for wiring and ductwork.
3. If the hood is to be ducted, install the ductwork so that is flush
to the range hood’s mounting surface.
• Refer to FIGURE 1 if the range hood is to be installed with a
horizontal discharge.
• Refer to FIGURE 2 and FIGURE 3 if the range hood is to be
installed with a vertical discharge.
4. Run two-conductor wire (with ground) from a power source to
the hood location. Bring approximately 12” of wiring through
wiring hole in cabinet.
5. Drill four 3/32” diameter pilot holes at points where mounting
holes are marked in cabinet bottom.
6. Insert four (4) mounting screws, leaving approximately ¼” of
thread exposed.
7. Remove and retain the mounting screws securing the 3¼” x
10” and 7” duct transitions to the hood. Install the appropriate
duct transition as described in the installation section.
INSTALLATION
1. Remove the necessary duct opening and wiring knockout from
the range hood.
If the range hood is to be installed as a non-ducted unit,
remove the wiring knockout only.
If the range hood is to be installed as a ducted unit, a baffle
plate is provided to close off the non-ducted vent. Install baffle
plate (Refer to FIGURE 4) by sliding into place behind grille.
Use locator bumps to orient in grille.
2. For 7” round discharge installation, refer to FIGURE 5.
Secure 7” adapter (included) to top of hood using screws provided. Install 7” round damper (Model BP87, purchased separately).
For 3¼” x 10” vertical discharge installation, refer to FIGURE 6.
Secure 3¼” x 10” transition (if used) to top of hood.
For 3¼” x 10” horizontal discharge installation, refer to FIGURE 7. If using supplied 3¼” x 10” duct transition, secure it to
the range hood. Ensure that the damper flap operates fully and
freely. If it does not, remove the damper flap or make necessary modifications to the installation to insure full and free operation of the damper flap.
3. Feed the wiring through the access hold and into the electrical
box.
4. Align hood’s keyhole mounting slots over the four (4) partially
installed screws.
5. Making sure the duct positions over the hood’s duct transition,
push the hood against the rear wall. Secure hood by tightening
screws.
6. Using a long blade screwdriver, reach into the discharge opening and make sure the damper flap operates freely (vertical
discharge only).

LAMP INSTALLING
OR REPLACEMENT
1. Depress sides of light diffuser until tabs of diffuser disengage
from slots in hood. Remove diffuser.
2. Install (2) 40 watt maximum, Type A-15 appliance bulbs.
3. Replace difuser in hood by depressing sides and engaging tabs
in slots in hood.
FILTER INSTALLATION
AND REPLACEMENT
1. For ducted operation, install the aluminum mesh filter. For nonduct operation, install the non-ducted filter (Model BPQTF, sold
separately).
2. Refer to FIGURE 9. The filter slides into channels at the back
of the hood, on either side of the fan compartment, and snaps
under the spring clips near the front of the fan compartment.
FIGURE 8
MAINTENANCE
FILTERS
IMPORTANT: The aluminum filter should be removed once monthly
and washed in hot detergent water. Rinse in clear, warm water and
shake off excess moisture before replacing. The filter may also be
cleaned in your dishwasher.
IN A NON-DUCTED INSTALLATION: Replace filter every 3-6
months as needed.
CLEANING
The hood should be wiped off occasionally both inside and outside
using warm water, mild dish detergent and a soft cloth. Never use
scouring powders, steel wool pads or any other abrasive cleaners
which will destroy the hood’s finish.
