The State of California enacted the California Safe Drinking Water and Toxic Enforcement
Act of 1986, (Prop.65), which “prohibits any person in the course of doing business from
knowingly and intentionally exposing any individual to a chemical known to the State of
California to cause cancer or reproductive toxicity without first giving clear and reasonable
warning to such individuals.” The Governor’s Scientific Advisory Panel added carbon
monoxide to the list of hazardous chemicals known to cause reproductive harm.
In order to establish full compliance with Proposition 65, a yellow warning label has been
attached to each gas-fired.
Carbon monoxide would not be present in concentrations that would pose a “significant
risk” to the consumer when the equipment is installed, operated and maintained as follows:
1. Installed in accordance with all local codes, or in the absence of local codes, with the
current National Fuel Gas Code ANSI Z223.1 Latest Addenda.
2. Installed under a properly designed and operating exhaust hood.
3. Connected to the type of gas for which the unit is equipped.
4. Proper appliance pressure regulator installed on the gas supply line and adjusted for
the manifold pressure marked on the rating plate.
5. Adequate air supply to the unit.
6. The equipment is operated in the manner intended and using the proper utensil for that
type of appliance.
7. Keep the equipment clean and have it checked periodically.
8. Burner air adjustments, mechanical maintenance and repairs must be performed by
qualified service personnel
Warning If the equipment is not installed, operated and maintained in accordance with the
above requirements, concentrations of carbon monoxide in excess of the established
limits could be present in the kitchen environment.
ALL PERSONNEL IN THE WORKPLACE WHO MAY BE SUBJECT TO ANY
EXPOSURE OF CARBON MONOXIDE MUST BE WARNED OF SUCH POSSIBLE
EXPOSURE. THIS WARNING SHOULD BE CONVEYED IN A MANNER SO THAT IT IS
CLEARLY UNDERSTOOD BY THE EMPLOYEE. THE EMPLOYEE MUST BE ASKED IF
IN FACT HE OR SHE UNDERSTANDS THE CORRECT METHOD OF OPERATION OF
THE EQUIPMENT AND THAT A RISK OF EXPOSURE EXISTS IF THE EQUIPMENT IS
OPERATED IMPROPERLY.
WARNING
If not installed, operated and maintained in accordance with the manufacturer’s
instructions, this product could expose you to fuel or fuel combustion substances, which
can cause death or serious illness and which are known to the State of California to cause
cancer, birth defects or other reproductive harm.

Operations:
Read and understand all instructions and warnings in this manual before operating the
appliance. Save these instructions for future reference.
Always leave safety grills and filters in place. Without these components, operating
blowers could catch on to hair, finger and loose clothing.
NEVER dispose cigarette ashes, ignitable substances, or any foreign objects into blowers.
NEVER leave cooking unattended. When frying, oil in the pan can easily overheat and
catch fire. The risk of self combustion is higher when the oil has been used several times.
NEVER cook on “open” flames under the range hood. Check deep-fryers during
use: Superheated oil may be flammable.
Cleaning:
The saturation of greasy residue in the blower and filters may cause increased
inflammability. Keep unit clean and free of grease and residue built up at all times to
prevent possible fires.
Filters must be cleaned periodically and free from accumulation of cooking residue. Old
and worn filters must be replaced immediately.
DO NOT operate blowers when filters are removed. Never disassemble parts to clean
without proper instructions. Disassembly is recommended to be performed by qualified
personnel only. Read and understand all instructions and warnings in this manual before
proceeding.

SAFETY WARNING: Never put your hand into area housing the fan while the fan is
operating!
For optimal operation, clean range hood and all baffle / spacer / filter / grease tunnel / oil
container regularly / Regular care will help preserve the appliance of the range hood.
Cleaning Exterior surfaces:
Clean periodically with hot soapy and clean cotton cloth. DO NOT use corrosive or
abrasive detergent, or steel wool/scoring pads, which will scratch and damage the
stainless steel surface. For heavier soil use liquid degrease such as “Forumla 409" or
“Fantastic” brand cleaner.
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
towel to dry the hood.
After cleaning, you may use non abrasive stainless steel polish such as SM or ZEP, to
polish and buff out the stainless luster and grain. Always scrub lightly, with clean cotton
cloth, and with the grain.
DO NOT allow deposits to accumulate or remain on the hood.
DO NOT use ordinary steel wool or steel brushes. Small bits of steel may adhere to the
surface and cause rusting.
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. Rings with water exposure and wipe dry with a clean
cloth.
Cleaning Stainless Steel Baffle Filter:
IMPORTANT: Drain oil from baffles, spacers, filters, oil tunnels, oil containers before oil
residue overflow!
Remove all baffles, spacers, filters, grease tunnel, and oil containers and discard oil and
residue.
Wash with warm soapy water. NOTE: Stainless steel baffles, spacers and oil tunnel are
top rack dishwasher safe.
Dry thoroughly before replacing and follow directions for installation in reverse.
Filters should be cleaned after every 30 hours of use.
Replacing the light bulb:
