Installation Instructions
Mounting Height, Clearance, & Ducting
A minimum of 6” round duct work must be used to maintain
maximum air flow eciency with the 290/600 CFM internal
blower. A minimum of 8” to 10” round duct work must be used
with the 1000 CFM remote blower.
Always use rigid type metal ducts only. Flexible ducts could
restrict air flow by up to 50%.
Also use calculation (on page 8) 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 insert
duct output and as far apart, between the two as possible.
Minimum mount height between range top to insert bottom
should be no less than 24”.
Maximum mount height should be no higher than 36”.
It is important to install the insert at the proper mounting height.
Inserts mounted too low could result in heat damage and fire
hazard; while inserts mounted too high will be hard to reach and
will lose its performance and eciency.
