PWX WITH STANDING PILOT:

Thermostat calls for heat, completing the circuit to the aquastat and gas valve. The sequence is as follows: The LED light indicating a call for heat and circulator, in the control panel, will illuminate. The automatic vent damper will begin to open. When the vent damper is completely open and the end switches are made, the gas valve / burner LED light will illuminate and the main valve will open, lighting all the burners. The burners will continue to fire until either the thermostat or high limit, in the aquastat, is satisfied. If the high limit is satisfied and a call for heat remains from the thermostat, the main valve will close, shutting off gas supply to the burners and the

associated LED light in the control panel. The circulator will continue to operate and circulator LED light will remain on until the thermostat is satisfied.

Please note the main power LED light, in the control panel, will remain on until line voltage to the boiler is turned off or disconnected.
