What to Do In The Event Of a Range Top Grease Fire
•SMOTHER FLAMES with a tight fitting lid, cookie sheet, or metal tray, and then turn off the burner.
KEEP FLAMMABLE OR COMBUSTIBLE MATERIAL AWAY FROM FLAMES. If the flames do not
go out immediately, EVACUATE THE AREA AND CALL THE FIRE DEPARTMENT or 911.
•NEVER PICK UP A BURNING PAN –You May Get Burned.
•DO NOT USE WATER, including wet dishcloths or towels –a steam blast will result.
•Use an extinguisher ONLY if:
a) You have a Class A, B, C extinguisher and 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.
What to Do If You Smell Gas
•Extinguish any open flame.
•Do not try to turn on the lights or any type of appliance.
•Open all doors and windows to disperse the gas. If you still smell gas, call the Gas Company and
Fire Department right away.
CAUTION
1) For general ventilation use only. Do not use to exhaust hazardous or explosive materials and vapors.
2) To reduce the risk of fire, use only metal ductwork. Sufficient air is needed for proper combustion
and exhausting of gases through the flue (chimney) to prevent back drafting.
3) 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 code authorities.
4) Activating any switch on may cause ignition or an explosion.

Preparation before Installation
NOTE: TO AVOID DAMAGE TO YOUR HOOD,
PREVENT DEBRIS FROM ENTERING THE
VENT OPENING.
- Decide the location of the venting pipe from thehood
to the outside. (Figure 1)
- A straight, short vent run will allow the hood to
perform more efficiently.
- Try to avoid as many transitions, elbows, and long
run as possible. This may reduce the performance
of the hood.
- Temporarily wire the hood to test for proper
operation before installing. If the hood does not
operate, check the circuit breaker or house fuse. If
the hood is still not working, disconnect power
supply and check the continuity of all wire
connections.
- Peel protective film off the hood (if any).
- Use duct tape to seal joints between pipe sections.
- Make sure the cabinet has full access opening for
the hood as shown on Figure 2.
- Using reference on Page 15 to measurement and
create access opening for electrical wire and
exhaust under the cabinet.
