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 THEAREAAND CALLTHE FIRE DEPARTMENT or 911.
•NEVER PICK UPA BURNING PAN –You May Get Burned.
•DO NOT USE WATER, including wet dishcloths or towels –a violent 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

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.
5) Due to the size and weight of this hood, two people installation is recommended.

Preparations of Ductwork and Location
NOTE: TO AVOID DAMAGE TO YOUR
HOOD, PREVENT DEBRIS FROM
ENTERING THE VENT OPENING.
- Decide the location of the venting pipe from
the hood to the outside. Refer to Figure 1.
- A straight, short venting 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.
- Important: Peel any protective film off the hood
-Use duct tape to seal the joints between
pipe sections.

difficulty or your installation is unique.
3. Finish the ceiling surface. Be sure to
mark the location of the ceiling joists and
cross framing, or replace the mounting
template in the position of the ceiling joists
& cross framing.
4. Attach the telescopic stack to the ceiling
and securely fasten to the joists and cross
framing with eight screws (not provided)
as shown in Figure 3. Make sure screws
are driven into center of joists and cross
framing for maximum support.
5. Adjust the telescopic stack using
reference Fcalculated in Table 1 and
measurements on page 14. Tighten from
the side with four (4x8 mm) screws
(provided) as shown in Figure 3.

PAPER TOWEL ON STAINLESS STEEL.
For optimal operation, clean range hood and all baffle/spacer/filter/oil tunnel/oil container regularly.
*** Regular care will help preserve the appearance of the hood.
1. Use only mild soap or detergent solutions. Dry surfaces using soft cloth.
2. If hood looks splotchy (stainless steel hood), use a stainless steel cleaner to clean the surface of
the hood. Avoid getting cleaning solution onto or into the control panel. Follow directions of the
stainless steel cleaner. Caution: Do not leave on too long as this may cause damage to hood
finish. Use soft towel to wipe off the cleaning solution, gently rub off any stubborn spots. Use dry
soft towel to dry the hood.
3. DO NOT allow deposits to accumulate or remain on the hood.
4. DO NOT use ordinary steel wool or steel brushes. Small bits of steel may adhere to the surface
and cause rusting.
5. DO NOT allow salt solutions, disinfectants, bleaches, or cleaning compounds to remain in contact
with stainless steel for extended periods. Many of these compounds contain chemicals, which may
be harmful. Rinse with water after exposure and wipe dry with a clean lint free cloth.
For Baffle Filter models only: to Clean Baffle Filter/Oil Tunnel
CAUTION: DRAIN OIL FROM BAFFLE FILTERS, SPACERS & OIL TUNNEL REGULARLY TO
PREVENT OVERFLOW.

TROUBLE SHOOTING
Issue
Possible Cause
Solution
After Installation,
both motors and
lights are not
working.

Make sure the circuit breaker and the unit’s power is
ON. Use a voltage meter to check the power supply.
The wire connection is not secure.
Check and tighten wire connection.
Lights are
working, but
motor(s) is not.
The motor(s) is defective.
Replace the motor.
The capacitor(s) is defective.
Replace capacitor(s).
The range hood
is vibrating.
The blower system is not secure.
Tighten the turbine impeller/squirrel cage and air
chamber.
The turbine impeller/squirrel cage is not
balanced.
Replace the turbine impeller/squirrel cage.
Hood is not secured in place.
Check the installation of hood, tighten the mounting
bracket.
The motor is
working, but the
lights are not
working.
Light Fixture(s) is defective.
Replace the Light Fixture(s).
The light wiring(s) is loose.
Check wire continuity from processor board to light
transformer to halogen light housing(s).
Light transformer is defective.
Check power input and power output on the light
transformer. If it’s needed, replace the light
transformer.
The range hood
is not venting
out correctly.
The range hood is installed outside of the
manufacture recommended clearance.
Adjust the clearance between the range hoods and
cook top to 27” to 30”. For Island range hood, the
clearance between the range hoods and cook top is
30” to 36”.
There is no make-up air inside the house.
Open the window to enhance the performance of the
range hood by creating a sufficient make-up air.
Obstacle blocking the pipe work.
Remove all obstacles from the duct work.
The pipe size is smaller than the
suggested pipe size.
Change the ducting according to the manufacture
suggestion.
Cold air is
coming into the
