MOUNT HEIGHTS
INSTALLATION
Min 24"-Max 32"
36"
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 re hazard; while hoods mounted too high will be
hard to reach and will loose its performance
and eciency.
If available, also refer range manufacturer's
height clearance requirements and recommended hood mounting height above range.
Minimum clearance of 24”hood above range
height.
Maximum clearance 32" hood above range
height.
DUCTING
(AK8000AS, AK8100S, AK8200S)
A minimum of 6" round or 3-1/4” x 10"rectangular
duct must be used to maintain maximum air ow
eciency for AK8000/AK8100 and 8” minimum
must be used for AK8200.
Always use rigid type metal ducts only.
Flexible ducts could restrict air ow by up to 50%.
Also use calculation (on right) 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 8". If a reducer
is used, install a long reducer instead of a pancake
reducer. Reduce duct size as far away from opening as possible.
If turns or transitions are required:
Install as far away from opening and as far
apart, between 2, as possible.
Minimum Duct Size:
Round:
6" minimum for AK8000AS/AK8100S
8" minimum for AK8200S
Rectangular:
Requires an adapter. Readily available at most
hardware stores.
