The Purge Cycle Timer is a mechanical timer used to bring the boiler into active firing mode so that the load door may be safely opened. It is used on older Wood Gun boilers and those not using PLC based controls.
Excerpt from the Manual
The only time the load door can be safely opened is when the indicator light is on. If the indicator light is off, turn the purge timer clockwise to number 5 and wait two minutes before opening the door slowly. The waiting period will allow sufficient time for the fire to become re-activated and burn off any gases that may have collected in the fuel chamber during the off cycle.
