NOTES:
1.  IF ANY OF THE ORIGINAL WIRING SUPPLIED WITH THIS FURNACE MUST BE REPLACED, IT MUST BE WITH WIRE
     HAVING A TEMPERATURE RATING OF AT LEAST 105°C. WIRES 12, 18, 20, 48, 49, 50, 51, 92  & 93 MUST BE RATED TO 250°C.
2.  FOR PROPER AIRFLOW IN COOLING/HEAT PUMP MODE, "Y1" ON THE THERMOSTAT MUST BE CONNECTED TO "Y1"
     OF THE IFC. SEE INSTALLER'S GUIDE FOR FIELD WIRING.
3.  THE INDOOR BLOWER MOTOR AIRFLOW TABLES ARE LOCATED IN THE SERVICE FACTS. TO CHANGE AIRFLOW USE
     THE MENU/OPTIONS BUTTONS.
4.  LINE CHOKE AND WIRE BK/28 ONLY USED ON MODELS WITH 1 HP MOTORS.
5.  FLAME SENSE TEST PADS: 1 VDC = 1 MICROAMP. FLAME CURRENT CAN VARY DEPENDING ON THE VOM THAT IS USED 

     

     AND THE VOLTAGE SUPPLIED TO THE FURNACE.
     THE ACCEPTABLE RANGE IS 0.75-3 MICROAMPS.
6.  IF APPLICABLE CONNECTION FOR FACTORY
