burner compartment will need to move the juction box directly over.

4.Attach the junction box to the right side of the furnace, using the screws removed in step 2.

5.Check the location 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 filter 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 accordance 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 as shown in Figure 12.

IMPORTANT NOTE: To avoid possible equipment malfunction, route the low voltage wires to avoid interference with filter removal or other maintenance.

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 connections for a “heat only” system and “heat/cool system”.

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.

Integrated Ignition Control

WARNING

TO AVOID THE RISK OF INJURY, ELECTRICAL SHOCK 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) 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 servicing. Do not defeat this switch.

24VOLT 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.
