INSTALLING
FURNACE
(Continued)
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
ANSI/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 metallic sheathe cable, the installer must terminate the
supply wire in the terminal box opening.
Performance Check
Plug furnace into three-pronged outlet. If ignitor remains on after main burner
ignition or if the valve chatters, you may have reversed polarity.
1. Unplug furnace.
2. Turn off electricity to outlet.
3. Reverse 120-volt connections inside outlet.
4, Turn on electricity to outlet.
5. Plug in furnace. Ignitor should turn off after main burner ignites. If ignitor does
not turn off, or if valve continues to chatter, turn off furnace and unplug. Call a
qualified service person.
A'n'ACHING CABINET FRONT COVER
ACAUTION
Do not operate furnace 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 cover over top cabinet flange.
2. Secure the sides of front cover 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 cover
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. Make sure you secured flange on bottom of
furnace to flange on bottom front of cabinet.
