ALWAYS, when possible, reduce the number of
transitions and turns. If a long duct run is required,
increase duct size from 6” to 7” or 8”.
If turns or transitions are required: Install as far
away from duct opening and as far apart between
the two transitions as possible.
Minimum mount height between range top to hood
bottom should be no less than 26”.
Maximum mount height should be no higher than
34”.
It is important to install the hood at the proper

2. Change plastic jumper positioning as shown in FIG. K to set the desired maximum blower CFM.
3. Re-install PC board & continue with hood installation.
