Installation Instructions

Mounting Height, Clearance, & Ducting
A minimum of 10” round duct must be used for AK8200BS to
maintain maximum air flow eciency.
A minimum of 6” or 10” round duct must be used for AK8300BSX.
Always use rigid type metal ducts only. Flexible ducts could
restrict air flow by up to 50%.
Also use calculation (on page 8) to compute total available duct
run when using elbows, transitions and caps.
Min 24” - Max 36”
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 eciency.
If available, also refer range manufacturer’s height clearance requirements and recommended hood
mounting height above range.
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”.
For shipment and installation damages:
Ź Please fully inspect unit for damage before installation.
Ź If the unit is damaged in shipment, return the unit to the store in which it was bought for repair or
replacement.
Ź If the unit is damaged by the customer, repair or replacement is the responsibility of the customer.
Ź 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.
