Installation Instructions
Mounting Height, Clearance, & Ducting
A minimum of 6" round for AK65 and 7" round for AK21 and AK25 or 3-1/4" x 10" rectangular duct
must be used to maintain maximum air flow efficiency for vertical ducting. For horizontal ducting,
3-1/4" x 10" rectangular duct is the minimum size.
Always use rigid type metal ducts only. Flexible ducts could restrict air flow by up to 50%.
Use calculation worksheet 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 6" to 7" or 7" to 8".
If turns or transitions are required: Install as far away from duct opening and as far apart between
the two transitions 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 32".
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 loose
performance and efficiency.
If available, also refer to range manufacturer's height clearance requirements and recommended
hood mounting height above range. Always check your local codes for any differences.
For shipment and installation damages:
Please fully inspect unit for damage before installation.
If the unit is damaged in shipment, return the unit to the store in which it was bought for repair or
replacement.
If the unit is damaged by the customer, repair or replacement is the responsibility of the customer.
If the unit is damaged by the installer (if other than the customer), repair of replacement must be
made by arrangement between customer and installer.
