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 located in the blower compartment. Wire routing must not to 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.

GME95/AMEH96 FURNACE WITH 2-STAGE CONDENSER FIELD WIRING

The GME95/AMEH96 model furnaces may be used with a 2-stage outdoor air conditioner. A two stage cooling/single stage gas heat ther- mostat is required, in addition to a field supplied relay. The relay must have a 24VAC coil and contacts rated for up to 1 horse power at 125VAC.

1.Install the field supplied relay on the control mounting panel near the furnace ignition control. The relay should be installed such that the motor leads will reach the relay contact terminals.

2.Connect the “Y2” (high stage cool) thermostat terminal to one coil terminal of the field supplied relay. Connect the other field supplied relay coil terminal to the “C” terminal on the furnace ignition control. Typical 18AWG thermostat wire may be used.

3.Connect the common terminal of the field supplied relay to the “LINE-H” terminal on the furnace ignition control. Use wiring having copper conductors only and a temperature rating of at least 105°C.

4.Using the GME95/AMEH96 airflow tables in this manual, determine the motor speed tap needed to deliver the required high stage cooling airflow. Connect the selected motor speed tap to the normally open terminal on the field supplied relay. Use wiring having copper conductors only and a temperature rating of at least 105°C.

5.See the following wiring schematic.

WARNING

HIGH VOLTAGE!

TO AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRICAL SHOCK, DISCONNECT ELECTRICAL POWER BEFORE SERVICING OR CHANGING ANY ELECTRICAL WIRING.

The furnace’s integrated control module is equipped with line voltage accessory terminals for controlling power to an optional field-supplied electronic air cleaner.

The accessory load specifications are as follows:

Electronic Air Cleaner 1.0 Amp maximum at 120 VAC

Turn OFF power to the furnace before installing any accessories. Follow the air cleaner manufacturers’ instructions for locating, mount- ing, grounding, and controlling these accessories. Accessory wiring connections are to be made through the 1/4" quick connect terminals provided on the furnace integrated control module. The electronic air cleaner hot terminal is identified as EAC-H. The electronic air cleaner neutral terminal is identified as LINE NEUTRAL. All field wiring must conform to applicable codes. Connections should be made as shown below.
