ITY OF SHOCK INJURY OR DAMAGE TO THE EQUIP-
MENT.
CONNECT POWER SUPPLY WIRES
a. Remove the field wiring cover.
b. Insert 115 volt wires through the large plastic bush-
ing on the left side of the furnace ( See Figure 16).
If conduit is used it should be secured to the control
box.
c. Connect the “hot” wire to the BLACK pigtail lead,
and the “neutral” wire to the WHITE pigtail lead. Se-
cure all connections with suitable wire nuts and
wrap with electrical tape.
d. Connect the “ground” wire to the grounding screw.
e. Reinstall the control panel cover and secure
mounting screw.
CONNECT THERMOSTAT WIRES
a. Insert 24 volt wires through the small plastic bush-
ing just above the control panel.
b. Connect the thermostat wires to the furnace low
voltage pigtails (See Figure16).
c. Connect low---voltage circuit to the wall thermostat
pigtails.
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.

WALL THERMOSTAT
Avoid locations where the thermostat could be subject to
drafts from outside, or exposed to direct light from lamps,
sun, fireplaces, etc., or affected by air from a duct register
blowing directly on the thermostat.
The wall thermostat should be mounted approximately 5
feet from the floor. The preferred location is on an inside
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.
