DUCTING

A minimum of 6" round or 3-1/4" x 10"rectangular
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%.
Also use calculation (on right) to compute total
available duct run when using elbows, transitions
and caps.
ALWAYS, when possible, reduce the number of
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.
INSTALLATION
Minimum mounting height between range top to
hood bottom should be no less than 24".
Maximum mounting 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 hazard;
while hoods mounted too high will be hard to
reach and will lose performance and efficiency.
If available, also refer to range manufacturer's
*Min 88.94"
height clearance requirements and recommend-
*Max 114.65"
ed hood mounting height above range.
Extension kits available to accommodate
9'-12' ceilings.
*Minimum ceiling clearance 88.94" at 24" hood
mounting height.
**Maximum ceiling clearance 114.65" at 32"
hood mounting height.

Roof Cap
e.g.- 1 roof cap, 2x90 elbows, 1 45 elbow used:
=30' + 30' + 9' =69' used, 31' available for straight duct runs.
