DUCTING
A minimum of 6” round or 3-1/4” x 10” rectangular
duct must be used to maintain maximum air fl ow
effi ciency for single blower and 10” round duct for
dual, in-line, and external blowers.
Always use rigid type metal ducts only. Flexible
ducts could restrict air fl ow by up to 50%.
Also use calculation (on page 5) 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.
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 30”.
Maximum mount height should be no higher than
36”.
It is important to install the hood at the proper
mounting height. Hoods mounted too low could
result in heat damage and fi re hazard; while hoods
mounted too high will be hard to reach and will
lose its performance and effi ciency.
If available, also refer range manufacturer’s height
clearance requirements and recommended hood
mounting height above range.
