Fan Relay (R1 on wiring Diagram)
This two pole relay is provided to ensure that the fan will always run when the burner is firing,
as the temperature rise through the heat exchanger is much lower than for the standard heater, due
to the increased air flow. This Relay is additional to the fan thermostat which still provides for the "fan
run on" after burner operation.
