Electrical Supply
This range hood requires a 120V,
60Hz supply and draws a maximum of
3 amps. The electrical supply to the
range hood should be at least 17”
from the underside of the installed
range hood.
For a typical installation, where the
underside of the range hood will be
30” above the counter top and the
counter top is 36” above the floor
level, the electrical supply should be
76”” above floor level and no further
than 3” to the right (as you face the
wall) of the central axis of the range
hood.
The ducting connection to the hood
must be in line with the central
vertical axis of the range hood 1”
away from the back wall on which
the hood is to be mounted.
Range hoods may interrupt the
proper flow of combustion gases
from fireplaces, gas furnaces and
gas water heaters.
To minimize the risk of drawing
these lethal gases back into the
home, please follow the heating
equipment manufacturers safety
standards and guidelines carefully.
Refer to NFPA and ASHRAE for
additional information.

amp circuit breaker.
Duct Run Calculation
The maximum duct run before
effecting the performance of the
hood is 100’. Calculate your duct run
by measuring linear feet and adding
the elbows, transitions and caps
based on the table alongside.
