PREPARE THE CEILING OPENING
The hood should always be centered over the
cooktop. Make sure there is adequate space
in the ceiling structure to install the hood and
ductwork. The hood should be mounted 30”
to 72” above the cook top for best removal of
cooking impurities. Use joist size lumber to
frame in around the range hood opening. The
ceiling structure must be able to support the
weight of the hood. Fig 7.
Model ALU-E43 = 65 pounds.
Model ALU-E63 = 85 pounds.
PREPARE THE HOOD SUPPORT
Construct a wood framing system as shown
in Fig. 9.
The structure must be capable of supporting
its own weight, plus the weight of the hood.
Model ALU-E43 = 65 pounds.
Model ALU-E63 = 85 pounds.
