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.
