wall situated in an area with good air circulation, and where
the temperature will be reasonably representative of other
living areas the thermostat is controlling.

ELECTRICAL WIRING

CONNECT ELECTRICAL POWER AND CON-
TROLS
All electrical wiring within the furnace has been made at the
factory.
All wiring connected to the furnace must comply with and
be electrically grounded in accordance with the National
Electric Code and any applicable local codes or regula-
tions, (ANSI-C1 / NFPA-70), Canadian Standard and all lo-
cal codes having jurisdiction.
A separate 120 V.A.C. supply circuit must be used for the
furnace. The circuit should be protected by a 15 amp fuse
or circuit breaker.
Run the 120 volt supply through the opening in the side of
the furnace. Join the electrical supply wires with suitable
connectors to the electrical supply leads in the junction
box. Replace the junction box cover.
An approved strain relief connector at the junction box must
be used. When using a three wire system, connect the me-
chanical ground to the green headed screw in the back of
the junction box. See figure 14 and following wiring dia-
grams.
