4. Next, the blower proof switch on the Air/Fuel Valve (Figure 3-5) closes. The display will
show Purging and indicate the elapsed time of the purge cycle in seconds.
5. Upon completion of the purge cycle, the Control Box initiates an ignition cycle and the
following events occur:
(a) The Air/Fuel Valve rotates to the low-fire ignition position and closes the ignition switch.
The dial on the Air/Fuel Valve (Figure 3-6) will read between 25 and 35 to indicate that
the valve is in the low-fire position.
(b) The igniter relay is activated and provides ignition spark.
(c) The gas Safety Shut-Off Valve (SSOV) is energized (opened) allowing gas to flow into
the Air/Fuel Valve.
