DUCTING
A minimum of 6” round duct must be used to
maintain maximum air flow efficiency.
Always use rigid type metal ducts only. Flexible
ducts could restrict air flow by up to 50%.
Use calculation worksheet to compute total duct
work(page 5).
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
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 lose
its performance and efficiency.
If available, also refer range manufacturer’s height
clearance requirements and recommended hood
mounting height above range.
DAMAGE-SHIPMENT / INSTALLATION:
• Please fully inspect unit for damage before
installation.
• If the unit is damaged in shipment, return the unit
to the store in which it was bought for repair or
replacement.
• If the unit is damaged by the customer, repair or
replacement is the responsibility of the customer.
• If the unit is damaged by the installer (if other
than the customer), repair of replacement must
be made by arrangement between customer and
