The operating characteristics of the flame sensing circuit are outlined as follows:
1.
The flame probe is checked for proper functionality every time the heater is started. The heater
toggle switch is pushed to the “START” position. If the flame probe is in good condition, the purge
light is illuminated. If the flame probe is not good, the flame probe will require replacement.
2.
Once the flame probe is checked, the remaining internal and external heater sensors have power
available. If all sensors call for heater operation, after a 30 second time frame to complete the purge
cycle, the transformers and solenoids are energized, and the ignition light is illuminated.
3.
If no flame is at the burner or the flame probe is not positioned to monitor the flame, the flame
sensing relay will de-energize the solenoids and transformer after approximately 30 seconds. The
flame lock-out light will be illuminated.
The condition that resulted in the loss of flame at the flame
. The flame sensing relay is reset by switching the heater power switch to
“OFF”.
4.
The heater then can be restarted by repeating the operation steps.
Start-Up Procedure:
Note: The heater is designed to operate at various firing rates. The operator must adjust
the firing rate for correct operation based upon the conditions present.
