NOTES:
1. IF ANY OF THE ORIGINAL WIRING AS SUPPLIED WITH THIS FURNACE MUST BE REPLACED, IT MUST BE WITH WIRE HAVING A
TEMPERATURE RATING OF AT LEAST 105°C. WIRES 12, 48, 49, 50, AND 51 REQUIRE A TEMPERATURE RATING OF AT LEAST 250° C.
2. FOR PROPER AIRFLOW IN COOLING/HEAT PUMP MODES, Y1 MUST CONNECT FROM THE THERMOSTAT TO THE IFC LOW VOLTAGE
TERMINAL STRIP.
3. TO CHANGE AIRFLOW, REFER TO THE INTEGRATED FURNACE CONTROL MENU & OPTIONS TO SET AIRFLOW AND BLOWER DELAYS.
4. WIRE YL/45 AND RAF-2 ARE NOT PRESENT ON DOWNFLOW MODELS.
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 PROGRAMMING ONLY.
7. INDUCER WIRE NO. 2 MAY NOT BE PRESENT ON SOME SINGLE STAGE UNITS.
