panel.

c. This unit must be grounded and protected by a GFCI.
d. Suitable for use in damp locations only when installed in a GFCI PROTECTED branch-circuit

CAUTION
For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors. Take care when using cleaning

agents or detergents. Suitable for use in household cooking area.

WARNING
TO REDUCE THE RISK OF RANGETOP GREASE FIRE:

a. 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.

b. Always turn hood ON when cooking at high heat or when flaming food
c. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
d. Use proper pan size. Always use cookware appropriate for the size of the surface element.
e. Keep fan, filters and grease laden surfaces clean.
f. Use high setting on hood only when necessary.
g. Don't leave hood unattended when cooking.

h. Always use cookware and utensils appropriate for the type of and amount of food being prepared.

WARNING

TO REDUCE THE RISK OF INJURY TO PERSONS iN THE EVENT OFA RANGE TOP FIRE, OBSERVE THE FOLLOWING:
a. 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.

b. NEVER PICK UPAFLAMING PAN -You may be burned.
c. DO NOT USE WATER, including wet dishcloths or towels - a violent steam explosion will result.

d. Use an extinguisher ONLY if:

1. You know you have a Class ABC extinguisher, and you already know how to operate it.

2. The fire is small and contained in the area where it started.

3. The fire department is being called.

4. You can fight the fire with your back to an exit

WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a. Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards.

Including fire-rated construction.

b. Sufficient air is needed for power combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent

back-drafting. 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.
c. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
d. Ducted fans must always vent to the outdoors.

e. If this unit is to be installed over a tub or shower, it must be marked as appropriate for the application and be connected to a GFI

(Ground Fault Interrupter protected branch circuit).

g. NEVER place a switch where it can be reached from a tub or shower.

h. Make sure the power is off before installing, wiring or maintenancing.

WARNING

TO REDUCE THE RiSK OF FIRE, USE ONLYMETALDUCTWORK.

CAUTION
To reduce risk of fire and to properly exhaust air outside - Do not vent exhaust air into spaces within wails, ceilings,

attics, crawl spaces or garages.

OPERATION

Always leave safety grilles and filters in place. Without these components, operating blowers could catch onto hair, fingers

and loose clothing.
The manufacturer declines all responsibility in the event of failure to observe the instructions given here for installation,

maintenance and suitable use of the product. The manufacturer further declines all responsibility for injury due to
negligence and the warranty of the unit automatically expires due to improper maintenance.

It is important to install the hood at the proper

mounting height. Hoods mounted too low could
result in heat damage and fire hazard; while hoods

mounted too high will be hard to reach and wilt
lose its performance and efficiency.

DUCTING

A minimum of 6" round or 3-1/4" x 10" rectangular

duct must be used to maintain maximum air flow
efficiency for single blower and 10" round duct for

dual, in-line, and external blowers.

C

I

Always use rigid type metal ducts only. Flexible

ducts could restrict air flow by up to 50%.

Also use calculation (on page 5) to compute total

available duct run when using elbows, transitions
and caps.

ALWAYS, when possible, reduce the number or

transitions and turns. If long duct run is required,
increase duct size.

If turns or transitions are required; install as far
away from hood duct output and as far apart,

between the two as possible,

WARNING FiRE HAZARD

NEVER exhaust air or terminate duct work into spaces between walls, crawl spaces, ceiling, attics or garages.

All exhaust must be ducted to the outside.

Use metal ductwork only.

Fasten all connections with sheet metal screws and tape all joints with certified Silver Tape or Duct Tape.

SURFACE MAINTENANCE:

Clean periodically with hot soapy water and clean cotton cloth. Do not use corrosive or abrasive detergent,

or steel wool/scouring pads which will scratch and damage surface. Do not use products containing chlorine

bleach or orange cleaners.

For heavier soil use liquid degreaser.

After cleaning, you may use non-abrasive stainless steel polish/cleaners, to polish and buff out the stainless

luster and grain. Always scrub lightly using a micro fiber or clean cotton cloth and with grain.

Stainless Steel Baffle Filters

The stainless steel baffle filters are intended to trap residue and grease from cooking. Although the filters
should never need replacing, they are required to be cleaned every 30 days or more often depending on

cooking habits.

Filters may be placed in dishwasher at low heat or soaked in hot soapy water Dry filters and re-install before
using hood.

Removing Baffle Filters

1. Push filter toward back of range hood using handles.

2. Pivot front of filter downward.

3. Remove filter by pulling away from hood.

REPLACING LIGHT BULBS

CAUTION: Light bulb becomes extremely hot when turned on.

DO NOT touch bulb until switched off and cooled. Touching hot bulbs could cause serious burns.

Make sure all power is turned off and bulbs are not hot.

Remove by turning bulb counter clockwise. Note: Bulb does not unscrew; it turns 60 degrees, stops and

falls out.

If bulbs are difficult to turn due to prolonged use, firmly attach a glass suction cup approximately the
diameter of the bulb or use a rubber/latex glove and turn counter clockwise.

Replacement bulbs are available at specialty lighting stores. Purchase type MR16 (GU-10) 35W halogen.
