SAFETY INFORMATION
SAFETY INFORMATION
TO REDUCE THE RISK OF A FIRE, ELECTRICAL SHOCK,
AND/OR INJURY OBSERVE THE FOLLOWING:
• Unit is intended for indoor residential use only. If you should have questions,
contact the manufacturer at the address or telephone number listed in the
warranty.
• In case the unit should need to be cleaned or repaired, switch power off at
either breaker or by disconnecting the power cord from the outlet.
• Installation work and electrical wiring must be done by a qualified technician in
accordance with all applicable codes and standards, including fire-rated
construction.
• Sufficient air is needed for proper 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 of Heating, Refrigeration and Air Conditioning
Engineers (ASHRAE), and the local code authorities.
• Because the unit is made of stainless steel, it may contain sharp edges. Be
careful to avoid cuts and abrasions by wearing protective gloves during
installation and cleaning.
• Before you begin to cut or drill into the wall, verify that there is no electrical
wiring or any other hidden electrical components.
• Ducted fans must always be vented to the outdoors.
• Use metal ductwork when possible.
• Do not use this fan with any solid-state speed control device and/or in-line
motor.
• The unit must be properly grounded before beginning operation.

SAFETY INFORMATION
TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
• Regardless of heat level, never leave any surface materials unattended while
operating an open flame.
• Always turn hood ON when cooking at high heat or when flambéing food (i.e.
Crepes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
• Depending on amount of usage, clean ventilating fans and filters frequently.
Grease should not be allowed to accumulate on fan or filter. For instructions
on the how to clean, see maintenance page.
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE
EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE
FOLLOWING:
• 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 911.
• NEVER PICK UP A FLAMING PAN — Doing so may result in serious burns
and possibly spread the fire.
• DO NOT USE WATER – Grease fire must be extinguished before further
action may be taken. Using water will agitate the grease and may cause a
violent steam explosion.
• Use a Fire Extinguisher ONLY if:
 You have a Class ABC extinguisher, and you already know how to
operate it.
 The fire is small and contained in the area where it started.
 The fire department is being called.
 You are able to safely control the fire with your back to an open exit. *
