A minimum of 8” round or 3-1/4” x 10” rectangular 
duct must be used to maintain maximum air fl ow 
effi ciency.

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 26”. 

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.

Vertical Ducting:
8” round minimum

Horizontal Ducting:
8” round or 3 1/4” x 10” rectangular minimum
