c. Venting system warning tags to be removed and discarded.

!WARNING:

Failure to properly secure the flue pipe to the furnace may result in fire, explo- sion or asphyxiation when operating the furnace.

13. ELECTRICAL WIRING

Refer to the wiring diagram in these instructions or affixed to the inside of the control box cover for the wiring of your particular unit.

ELECTRICAL BRANCH SUPPLY CIRCUITS. Route all electrical wiring to the left side of the furnace. For installation of “A” Cabinet fur- naces, allow sufficient slack in the wiring if an optional cooling coil cabinet is added at a later time. Use of copper conductors is recom- mended.

!WARNING:

Any attempt to operate furnace before replacing transit-mode weather cap with upper roof jack section may re- sult in hazard of fire, explosion or as- phyxiation.

Power supply circuit to the furnace must be installed and grounded in accordance with the National Electrical code (ANSI-C1/NFPA-70), or Canadian Electric Code Part 1 (CSA 22-1) and all local codes having jurisdiction.

CONNECT POWER SUPPLY WIRES

a.Remove the furnace control panel cover.

b.Insert 115 volt wires through the strain relief on the left side of the furnace control box (see Figure 25).

c.Connect the “hot” wire to the BLACK pigtail lead, and the “neutral” wire to the WHITE pigtail lead. Secure all connections with suitable wire nuts.

d.Connect the “ground” wire to the grounding screw.

e.Reinstall the control panel cover and secure with the original mounting screws.

CONNECT THERMOSTAT WIRES

a. Insert 24 volt wires through the plastic grom- met just above the control panel.

b. Connect the thermostat wires to the furnace low voltage pigtails (see Figure 25).

c. Connect low-voltage circuit to the wall ther- mostat.

d.A hole may be made in the furnace cabinet to ease thermostat wiring. Make sure that the wiring is protected from the sharp edge of the added hole.

NOTE: The thermostat should be installed 4 to 5 feet above the floor on an inside wall which is relatively free from direct sources of heat or
