Installation Instructions
Mounting Height, Clearance, & Ducting
A minimum of 8” round duct or 3-1/4” x 10” rectangular duct is recommended to maintain maximum
air flow eciency for single blower and 10” round duct for dual internal blower for both vertical and
horizontal ducting.
Always use rigid type metal ducts only. Flexible ducts could restrict air flow by up to 50%.
Also use the ducting calculation sheet (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 from 8” to 10”.
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 34”.
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. Always check your local codes for any dierences.
Duct cover extension kit available for ceiling heights up to 12 feet. Turn to the list of parts and
accessories section for part number and ordering information.
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.
