Installing Your Furnace
GROUNDING
The appliance when installed must be electrically grounded in
accordance with local codes and ordinances or in their absence,
with National Electrical Code (ANSI/NFPA 70) or Canadian
Electrical Code (CSA C22.1) if an external electrical source is
utilized. This appliance is equipped with three-prong (grounding)
plug for your protection against shock hazard and should be
plugged directly into a properly grounded three-prong receptacle.
Do not cut or remove the grounding prong from this plug.
A ground lug is installed for the ground connection. Use a copper
conductor (#AWG) from the unit to a grounded connection in the
electric service panel or a properly driven and electrically
grounded ground rod.
ELECTRICAL POWER SUPPLY
Remove three-prong (grounding) service cord from the envelope
parts package to be installed in the furnace. Remove 7/8 inch
diameter (22mm) knockout at the left or right bottom side panel to
route the three-prong service cord to an electrical outlet.
1. Insert the nylon cap attached to the end of the three-prong
service cord thru the 7/8-inch diameter knockout into the
burner control assembly area and insert it into the nylon plug
attached to the outer casing bottom. If desired, you may route
the thermostat wire alongside of the service cord and thru the
same opening or choose another entry into the burner control
assembly area.
2. Attach 7/8-inch diameter strain relief around the three-prong
service cord and thermostat wire (if thermostat wire is routed
thru the knockout). Insert the 7/8-inch strain relief into the 7/8-
inch hole in the side panel of furnace.
Replacement Part Listing:
WARNING: Do not insert the three-prong
(grounding) service cord inside the burner control
assembly area more than 10 inches (245mm). This
could cause damage to the electrical cord resulting
in electrical shock hazard and/or fire.
A branch circuit including this furnace must not exceed 15
Amperes. Run a separate 115V, 60Hz. 15 Ampere circuit from a
separate circuit breaker or fuse in your service panel.
WALL THERMOSTAT WIRING
Run thermostat wire to the furnace. Connect thermostat to the two
wires marked "Thermostat" extending from top of furnace, using
