NOTE:
Equipment type (Single-stage cooling, Two-stage
cooling, Single-stage heat pump, Two-stage heat pump)
MUST
be setup through the OdS menu by the installer for
proper system operation. See Using Push-Button Switches
for instructions on how to navigate the control menu.
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
120 Volt and 24 Volt wiring.
A single-stage thermostat with only one heating stage is
needed to control this furnace.

WARNING
4. Attach the junction box to the left side of the fur nace,
using the screws removed in step 2.
5. Check the location of the wiring. 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 fil ter removal or other maintenance.
After the junction box is in the desired location, use washers
to connect field-supplied conduit to the junction box in accor
-
dance with NEC and local codes. Connect hot, neutral, 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.
IMPORTANT NOTE:
To avoid possible equipment malfunc-
tion, route the low voltage wires to avoid interference with filter
removal or other maintenance.

WARNING
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)
connection and the unpainted surface on the furnace.
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.
Low voltage connections can be made through either the right
or left side panel. Thermostat wiring entrance holes are locat-
ed in the blower compartment. The following figure shows
connections for a “heat only” system and “heat/cool system”.
