DUCTING
9"
36"
Min 98"-Max 124”
Min 28"-Max 36"
Min 34"-Max 52"
Minimummount height between range top to hood bot-
tom should be no less than 28".
Maximum mount height should be no higher than 36".
It is importantto install the hood at the proper mounting
height. Hoods mountedtoo low could result in heat
damage and fire hazard; while hoods mountedtoo 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
mountingheight above range. Always check your local
codes for any differences.
A minimumof 6” round or 3-1 / 4 x 10"
rectangular duct work must be used to maintain
maximumair flow efficiency with the 600 cfm
internal blower. A minimumof 10” to 8” round must
be used with the 1000 cfm external blower.
Always use rigid type metal duct work only.
Flexible ducts could restrict air flow by up
to 50%.
Use calculation worksheet to compute total
duct work.
ALWAYS, when possible, reduce the number
or transitions and turns. If a reducer is used,
install a long reducer instead of a pancake
reducer. Reduce duct size as far away from
opening as possible.
If turns or transitions are required:
Install as far away from opening and as far
apart, between 2, as possible.
Minimum Duct Size:
Round - 6” minimumat 600 cfm
Round - 10” to 8” minimum at 1000 cfm
Rect angular - 3 1/4” x 10” minimum only if
using internal blower at 600 cfm. Using
rectangular ductwork will require a transition
adapter (not provided, but readily available at
most hardware stores).
DAMAGE-SHIPMENT/ INSTALLATION:
• Please fully inspect unit for damage
befor e installation.
• If the unit is damaged in shipment , return
