ELECTRICAL WIRING

WARNING
!
TURN OFF ELECTRIC POWER AT
FUSE BOX OR SERVICE PANEL
BEFORE MAKING ANY ELECTRICAL
CONNECTIONS. FAILURE TO DO SO
CAN CAUSE ELECTRICAL SHOCK
RESULTING IN PERSONAL INJURY
OR DEATH.
NOTE: Electric to furnace must be
supplied by commercial utility. Proper
voltage is 110-125 volts.
WARNING
!
THE CABINET MUST HAVE AN
UNINTERRUPTED GROUND
ACCORDING TO THE LATEST
EDITION OF THE NATIONAL
ELECTRICAL CODE, ANSI/ NFPA70-
OR IN CANADA, THE CANADIAN
ELECTRICAL CODE, CSA-C221 OR
LOCAL CODES THAT APPLY. DO
NOT USE GAS PIPING AS AN
ELECTRICAL GROUND. A GROUND
SCREW IS PROVIDED IN THE
JUNCTION BOX. FAILURE TO DO SO
CAN CAUSE ELECTRICAL SHOCK
RESULTING IN PERSONAL INJURY
OR DEATH.
IMPORTANT: If servicing IFC, be sure to
replace grounding screw. See Figure 28.
NOTE: If grounding screw is not
replaced, furnace will not operate.
Flame cannot be sensed.
WARNING
!
THIS FURNACE IS EQUIPPED WITH A
BLOWER DOOR SAFETY SWITCH.
DO NOT DISABLE THIS SWITCH.
FAILURE TO FOLLOW THIS
WARNING CAN RESULT IN
ELECTRICAL SHOCK, PERSONAL
INJURY OR DEATH.
IMPORTANT: The furnace must be
installed so that the electrical
components are protected from water
(condensate).
Before proceeding with the electrical
connections, be certain that the voltage,
frequency and phase corresponds to
that specified on the furnace rating
plate. For single furnace application,
maximum over-current protection is 15
amperes.
Use a separate fused branch electrical
circuit containing a properly sized fuse
or circuit breaker. Run this circuit directly
from the main switch box to an electrical
disconnect that is readily accessible and
located within site of the furnace.
Connect from the electrical disconnect
to the junction box on the left side of the
furnace, inside the blower compartment.

For the proper connection, refer to the
appropriate wiring diagram located on
the inside cover of the furnace control
box and in these instructions.
NOTE:
The electrical junction box may be
moved to the right side if necessary. A
knockout is provided. Seal the opposite
hole with plug provided.
NOTE: L1 (hot) and N (neutral) polarity
must be observed when making field
connections to the furnace. The ignition
control may not sense flame if L1 and
Neutral are reversed at junction box.
See Figure 28.
