INSTALLATION
MOUNT HEIGHTS
Minimum mount height between range top to
hood bottom should be no lessthan 24".
96"
36"
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.
DUCTING ze
A minimum of 6" round or 3-1/4" x 10"rectangular _
duct must be used to ma nta n max mum a r f ow

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Always use rigid type metal ducts only,
Flexible ducts could restrict air flow by up to 50%.
Duct RunCalculation:
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
increaseduct sizefrom 6" to 7 or 8". If a reducer
is used, install a long reducer instead of a panca
reducer. Reduceduct size asfar away from open
ing as possible.
If turns or transitions are required:
Install asfar away from opening and asfar
apart, between 2, aspossible.
