maintain maximum air flow efficiency.
Always use rigid type metal ducts only. Flexible

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
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
loose performance and efficiency.
If available, also refer to range manufacturer's
height clearance requirements and recommended
ZRO
hood mounting height above range. Always check
