Electrical Connections

Make wiring connections to the unit as indicated on enclosed wiring diagram. As with all gas appliances using electrical power, this furnace shall
be connected into a permanently live electric circuit. It is recommended that furnace be provided with a separate "circuit protection device"
electric circuit. The furnace must be electrically grounded in accordance with local codes or in the absence of local codes with the National
Electrical Code, ANSI/NFPA 70 or CSA C22.1 Electrical Code, if an external electrical source is utilized. The integrated furnace control is
polarity sensitive. The hot leg of the 120V power supply must be connected to the black power lead as indicated on the wiring diagram.
Refer to the Wiring Diagram section in this document and Unit Wiring Diagram attached to the furnace.

HEATING THERMOSTAT, ONE / TWO STAGE AC OR HEAT PUMP
NOTES:
Outdoor Unit
1) HP = Wiring used for Heat Pump systems.
(No Transformer)
2) Y1 and/or Y2 must connect from the thermostat to the IFC
for proper airflow.
X2
3) Remove Y1-O jumper for Hp systems. O terminal must be
connected as shown for gas heating operation during defrost.
4) If the thermostat does not have W2, or there are not enough
R
conductors jumper W1 to W2 at the IFc
5) A/TCONT824 thermostats do not require the use of X2.
6) For PWM (BK) enabled thermostats, cut the BK jumper
