utilities.
3) Ducted fans must be vented to the outside.
a) Before servicing or cleaning unit, open the light panel and SWITCH POWER OFF AT SERVICE
PANEL.
b) Clean all grease laden surfaces frequently. To reduce the risk of fire and to disperse air
properly, make sure to vent air outside. DO NOT vent exhaust air into wall spaces, attics, crawl
spaces or garages.

KEEP FLAMMABLE OR COMBUSTIBLE MATERIAL AWAY FROM FLAMES. If the flames do not
go out immediately, EVACUATE THE AREAAND 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 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.

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 the hood to
the outside. Refer to 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.
Important: Peel protective film off the hood, if any.
Use duct tape to seal joints between pipe sections.
CAUTION: If moving the cooking range is
necessary to install the hood, turn off the power in an
electric range at the main electrical box. SHUT OFF
THE GAS BEFORE MOVING A GAS RANGE. And use a
protective covering to protect cooktop and/or
countertop from damage.
Custom Hood Preparation
1. The custom hood frame must be sized to shape and the
weight of the insert. Refer to Measurements and
Diagrams on Page 13.
2. Install the Exhaust Plate using 4 screws. Refer to
Figure 2.
3. It must have a sturdy base (1/2 inch thick plywood
recommended) to sustain the weight of insert.
4. If an optional liner will be installed, the side of the wood
cabinet must be sturdy (1/2 inch thick plywood
recommended).
5. It is recommended to install a rear and front stud
support. Refer to Figure 3. The stud supports are
located 1-1/2” up from the base of the wood frame.
Liner Installation
6. The custom/wood hood must have a sturdy base to
accommodate the cut-out for the inset. The base must be
recessed to accommodate the height of the liner (See
liner dimension on Page 14)
7. Secure the liner to the bottom of the base using screws
(not included) appropriate for the size and material of your
wood frame.
8. Position the liner so that it aligns with the back edge of
the custom wood frame. Use a pen to trace the outline of
the pre-cut area. Remove the liner and proceed to Hood
Preparation Before Installation on Page 6.
9. Install the liner with 5 screws (not provided).

Figure 5.
15. Please refer to local codes for the usage of the damper
(included). If necessary, remove the damper
mechanism and install as exhaust connector.
Hood Preparation Before Installation
CAUTION: If moving the cooking range is necessary
to install the hood, turn off the power in an electric range at
the main electrical box. SHUT OFF THE GAS BEFORE
MOVING A GAS RANGE.
16. Determine and mark the centerlines on the base of the
wood frame where the insert will be installed.
17. Determine and make all necessary cuts in the wall or
ceiling for the ductwork. Note: Install the duct work
before installing the insert.

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.

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.
