VENTING REQUIREMENTS
Determine which venting method is best for your application.
Ductwork can extend either through the wall or the roof.
The length of the ductwork and the number of elbows should
size of the ductwork should be uniform. Do not install two
elbows together. Use duct tape to seal all joints in the ductwork
around the cap.
Flexible ductwork is not recommended. If it is used,
each foot of exible ductwork used is equivalent to
two feet of straight metal ductwork when calculating
the ductrun length. Thus, a exible elbow equals two
standard elbows.
for exhaust duct before making cutouts. Do not cut a joist or
stud unless absolutely necessary. If a joist or stud must be
cut, then a supporting frame must be constructed.

ELECTRICAL REQUIREMENTS
A 120 volt, 60 Hz AC-only electrical supply is required on a
separate 15 amp fused circuit. A time-delay fuse or circuit
breaker is recommended. The fuse must be sized per local
codes in accordance with the electrical rating of this unit as
CONNECTED WITH COPPER WIRE ONLY. Wire sizes
must conform to the requirements of the National Electrical

cable so the appliance can be moved if servicing is ever nec-
essary. A UL Listed, 1/2" conduit connector must be provided
at each end of the power supply cable (at the appliance and
at the junction box).
When making the electrical connection, cut a 1 1/4" hole
in the wall. A hole cut through wood must be sanded until
smooth. A hole through metal must have a grommet.
