Verification of Proper Operation:

1. Place the thermostat in the heating mode.
2. Initiate a call for heat by raising the thermostat setting 5 degrees above the room temperature.
3. Observe the furnace: If properly wired, the following start-up sequence should be observed:
   • The red LED on the IFC should start a fast flash sequence.
   • The draft inducer should energize, and then the igniter should start to glow.
   • After the igniter heat up time has expired, the gas valve should be energized – listen for the “click”, the gas will then ignite.
   • After 45 seconds the main blower will turn on.
