WARNING - TO REDUCE THE RISK OF A RANGE TOP 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 flambeing food. (i.e. Crepes Suzette,
Cherries Jubilee, Peppercorn Beef Flambe’).
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.
WARNING

FIRE, OBSERVE THE FOLLOWING:
a) SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray, then turn o the burner. BE
CAREFUL TO PREVENT BURNS. If the flames do not go out immediately, EVACUATE AND CALL THE
FIRE DEPARTMENT.
b) NEVER PICK UP A FLAMING 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.

Installation Instructions
Mounting Height, Clearance, & Ducting
A minimum of 8” round must be used to maintain maximum air flow eciency for single blower and
10” round duct for dual blower for both horizontal and vertical ducting.
A 3-1/4” x 10” rectangular duct may also be used for single blowers for horizontal ducting
Always use rigid type metal ducts only. Flexible ducts could restrict air flow by up to 50%.
Also use calculation (on page 11) 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.
Minimum mount height between range top to hood bottom should be no less than 24”.
Maximum mount height should be no higher than 36”.
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 will lose its
performance and eciency.
If available, also refer range manufacturer’s height clearance requirements and recommended hood
mounting height above range.
For shipment and installation damages:
ŹPlease fully inspect unit for damage before installation.
ŹIf the unit is damaged in shipment, return the unit to the store in which it was bought for repair or
replacement.
ŹIf the unit is damaged by the customer, repair or replacement is the responsibility of the customer.
ŹIf the unit is damaged by the installer (if other than the customer), repair of replacement must be
made by arrangement between customer and installer.
