The furnace control module energizes the humidifier

whenever the combustion blower is energized (if there

is an optional air cleaner on the system, the humidifier

is not energized until the air cleaner is energized). The

control module energizes the air cleaner whenever the

air circulation blower is energized.

Low Voltage Wiring

Low voltage wiring may enter through the right or left

side of the furnace. See Section II for hole locations.

Run the thermostat wires through either hole, up through

a grommet in the blower deck, and to the ignition control

module. (Figure 22)

CAUTION

To avoid possible equipment malfunc-

tion, be careful to route the low voltage

wires so as not to interfere with filter

removal or other maintenance.

Low voltage wires may then be connected to the termi-

nal strip as shown below.

Figure 22

Typical Field Wiring

(24 VAC Control Circuit)

A 40\/ transformer and auxiliary fan relay are built into

the furnace so that is may be used with most cooling

equipment.
Consult the wiring diagram for both 115V and 24V

wiring details. The wiring diagram is located inside the

blower compartment door.

Line Voltage Connection of Optional

Humidifier and Electronic Air Cleaner

The control module in this furnace is equipped with line

voltage accessory terminals to be used for controlling

the power to an optional field-supplied humidifier and/or

electronic air cleaner.

CAUTION

Label all wires prior to disconnection

when servicing controls, wiring errors

can cause improper and dangerous op-

eration. Verify proper operation after ser-

vicing.

Accessory Load Specifications

Air Cleaner: 1.0 Amp maximum at 120 VAC

Humidifier: 1.0 Amp maximum at 120 VAC

Accessory Installation

Follow the electronic air cleaner and humidifier manu-

facturers instructions for mounting and electrically

grounding these accessories. Check that the power

supply to the furnace has been disconnected. Wire the

accessories to the furnace control module as shown

below. All connections to the control module are to be

made through 1/4 (.250") receptacle (female) terminals.
If it is necessary for the installer to supply additional line

voltage wiring to the inside of the furnace, the wiring

must comply with all local codes. This wiring must have

a minimum temperature rating of 105° C and must be

routed away from the burner compartment. All line

voltage wire splices must be made inside the furnace

junction box.
