Always use rigid type metal ducts only.
Flexible ducts could restrict air flow by up to 50%.
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 haz- ard; while hoods mounted too high will be hard to reach and will loose its performance and efficiency.
If available, also refer range manufacturer's height clearance requirements and recom- mended hood mounting height above range.
Minimum clearance of 24”hood above range height.
Maximum clearance 32" hood above range height.
Minimum Duct Size:
Round:
6" minimum for AK8000AS/AK8100S 8" minimum for AK8200S Rectangular:
Requires an adapter. Readily available at most hardware stores.
Duct Run Calculation:
Maximum run
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 open- ing as possible.
If turns or transitions are required:
Install as far away from opening and as far apart, between 2, as possible.
