Applies to:
The gas control valve sends regulated gas to the burners when the controller calls for heat. The control valve can be turned on or off. In the on position, and the power switch on, a spark ignitor lights a standing pilot, and when the control calls for heat, the valve is opened and the burners are ignited.
