6. Rotate the junction box 180 degrees so the access
panel continues to face forward. The open snap
bushing should now be on the left.
7. Attach pressure switch bracket to left side of furnace
where the junction box was using the screws saved
in Step 4. The “L” bracket must point toward the
front of the furnace. Reroute pressure switch wires
through the split grommet on the left side of the
blower deck. Reconnect wires using the wiring dia-
gram inside the blower door.
8. Reroute remaining wires through split grommet on
the right side of the blower deck.
9. Insert remaining wires through the open bushing in
the bottom of the junction box.
10. Attach the junction box to the right side of the fur-
nace, using the screws removed in step 2.
11. Reconnect the hose to the pressure switch.
12. Check the location of the pressure hose and all wir-
ing. Confirm that it will not be damaged by heat from
the burners or by the rotation of the fan. Also confirm
that wiring location will not interfere with filter re-
moval or other maintenance.
After the junction box is in the desired location, use wash-
ers to connect field-supplied conduit to the junction box in
accordance with NEC and local codes. Connect hot, neu-
tral, and ground wires as shown in the furnace wiring
diagram. The wires and ground screw are located in the
furnace junction box.
Low voltage wires may be connected to the terminal strip
as shown in the “Integrated Ignition Control” figure.
IMPORTANT NOTE: To avoid possible equipment mal-
function, route the low voltage wires to avoid interference
with filter removal or other maintenance.
WARNING
To avoid the risk of electrical shock, injury, or death,
the furnace must be electrically grounded in
accordance with local codes or, in their absence,
with the latest edition of The National Electric Code.
To ensure proper unit grounding, the ground wire should
run from the furnace ground screw located inside the
furnace junction box all the way back to the electrical panel.
NOTE: Do not use gas piping as an electrical ground.
To confirm proper unit grounding, turn off the electrical
power and perform the following check.
1. Measure resistance between the neutral (white) con-
nection 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 servicing. Do not defeat this switch.
24 VOLT THERMOSTAT WIRING
NOTE: Wire routing must not interfere with circulator
blower operation, filter removal, or routine maintenance.
As a two-stage furnace, the furnace integrated control
module provides terminals for both “W1” and “W2”, and
“YLO” and “Y” thermostat connections. This allows the
furnace to support the following system applications: ‘Two-
Stage Heating Only’, ‘Two-Stage Heating with Single-
Stage Cooling’, and ‘Two-Stage Heating with Two-Stage
Cooling’. Refer to the following figures and table 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. Wire routing must
not interfere with circulator blower operation, filter removal,
or routine maintenance.
This furnace is equipped with a 40 VA transformer to
facilitate 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.
