CONNECTING TO
ELECTRICAL SUPPLY
IMPORTANT: Follow all local codes when
connecting electricity to furnace. In the
absence of local codes, refer to the latest
edition of the National Electrical Code
ANS/NFPA No. 70. If you are not familiar
with wiring codes, have a qualified
electrician do the wiring.
It is best to plug furnace into a separate
and permanent electrical line circuit.
1. Supply a 120-volt, 60-cycle, grounded
outlet at furnace location.
2. The furnace has a three-pronged
(grounded)
plug.
Use
only
a
grounded, three-prong outlet.
IMPORTANT: Some local codes require
rigid or semi-rigid conduit or metallic
sheathe cable. When using a semi-rigid
or metallic sheathe cable, the installer
must terminate the supply wire in the
terminal box opening.
ATTACHING CABINET
FRONT GRILLE
CAUTION: Do not operate fur-
nace with front cover removed or
mounted wrong. If front cover is
mounted wrong, you cannot secure
it to cabinet with screws.
1. Hook top of front grille over top cabi-
net flange.
2. Secure the sides of front grille to lower
sides of furnace cabinet with two
screws provided (see Figure 17).
IMPORTANT: You may have removed
furnace from furnace cabinet during
installation. You must correctly install
furnace within cabinet. If not, front grille
will not properly attach to cabinet. Make
sure gaskets for intake and exhaust tubes
are in place. Make sure intake and
exhaust tubes extend into vent caps on
cabinet back and are secured with screws
(see Figure 17A). Make sure you secured
flange on bottom of furnace to flange on
bottom front of cabinet.

THERMOSTAT
CONTROL
OPERATION
The thermostat responds to the room
temperature. When the room temperature
drops below the thermostat setting, the
thermostat turns the furnace burner and
blower on. When the room temperature
goes above the thermostat setting, the
thermostat turns the furnace burner off.
The blower will continue to blow about two
to three minutes after the burner goes out.
The thermostat keeps the room at a
constant temperature.
