Line voltage connections can be made through either the right
or left side panel. The furnace is shipped configured for a right
side electrical connection. To make electrical connections
through the opposite side of the furnace, the junction box must
be relocated to the left side prior to making electrical connec-
tions. To relocate the junction box, perform the following steps.
1. Remove the burner compartment door.
2. Remove and save the two screws securing the junction
box to the side panel.
3. Relocate junction box and associated plugs and grommets
to opposite side panel. Secure with screws removed in
step 2.

NATIONAL LECTRICAL ODE
To ensure proper unit grounding, an earth ground wire must
be connected between the furnace ground screw located in-
side the furnace junction box and the electrical service panel.
NOTE: Do not use gas piping as an electrical ground. To con-
firm proper unit grounding, turn off the electrical power and
perform the following check.
1. Measure resistance between the neutral (white) connection
and one of the burners.
2. Resistance should measure 10 ohms or less.
This furnace is equipped with a blower door interlock switch which
interrupts unit voltage when the blower door is opened for ser-
vicing. Do not defeat this switch.

When installed with a non-communicating thermostat, the
furnace integrated control module provides terminals for both
"W1" and "W2", and "Y1" and "Y2" thermostat connections.
This allows the furnace to support the following system applica-
tions: 'Two-Stage Heating Only', 'Two-Stage Heating with Single
Stage Cooling', and 'Two-Stage Heating with Two-Stage Cool-
ing'. Refer to the following figures for proper connections to the
integrated control module.
Low voltage connections can be made through either the right or
left side panel. Thermostat wiring entrance holes are located in
the blower compartment. The following figure shows connec-
tions for a "heat/cool system".
This furnace is equipped with a 40 VA transformer to facilitate
THE
use with most cooling equipment. Consult the wiring diagram,
located on the blower compartment door, for further details of
115 Volt and 24 Volt wiring.
NOTE: Use of cooling ramping profiles and dehum feature
requires a jumper between Y1 and O when a straight cooling
unit is used.

The auxiliary contacts are shipped with a factory installed
jumper. As an option, the auxiliary contacts may be wired to
.
a normally closed float switch. In the event of open con-
tacts, the gas heat and cooling will be disabled until the con-
dition is corrected. These are 24 volt terminals powered in-
ternally, do not apply another voltage source to these termi-
nals.
