DUCTING
A minimum of 6” round duct must be used to
maintain maximum air flow efficiency.
Always use rigid type metal ducts only. Flexible
ducts could restrict air flow by up to 50%.
Use calculation worksheet to compute total duct
work (Page 5).
ALWAYS, when possible, reduce the number of
transitions and turns. If a long duct run is required,
increase duct size from 6” to 7” or 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
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
loose its 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.
Duct cover extension kit available for ceiling heights
up to 12 feet. Turn to page 19 for part number and
ordering information.
