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
cabinet bottom should be no less than 26”.
Maximum mount height should be no higher than
36”.
It is important to install the liner at the proper
mounting height. Liners mounted too low could
