- The sensor probe must be adjusted so that it senses flame on both the high and low gas presure.
- It must be close enough to the metal fin in the burner so as to conduct 120V DC from the flame sensor probe to the metal.
- Be sure the probe does not make contact to the metal causing a grounding condition.
- The wire may be bent into any shape to get the desired result. Caution: Do not break the insulator when adjusting the wire.
Although the insulator looks like a spark plug there are no moving parts and no mechanical contacts to wear out.
The light for the heater is used as a meter to indicate proper probe adjustment. When the heater light "flickers" or fails to come on you do not have a proper probe adjustment.
The above adjustments assume the operator has confirmed the wires coming from the burner control box are tight and in good condition. The DC wire looks similar to a spark plug wire and is attached to the flame probe. The white ground wire is attached to the burner housing.
