Diagnostics

No. Continue.

2.Is the burner enable relay energized?

No. There is an open in the 24VAC circuit. Determine cause and rectify.

Yes. Continue.

3.Is the burner enable relay's normally open contact closed?

No. Replace relay.

Yes. Continue.

4.Is there a pilot flame present?

No. Refer to the Installation, Operation and Maintenance Manual for guidance in troubleshooting the flame relay or ignition module.

Yes. Continue.

5.Is the flame relay or ignition module main valve terminal energized?

No. Refer to the Installation, Operation and Maintenance Manual for guidance in troubleshooting the flame relay or ignition module.

Yes. Continue.

6.Is the gas valve/burner status relay energized?

No. There is an open in the main valve control circuit. Determine cause and rectify.

Yes. Continue.

7.Is the gas valve/burner status relay's normally open contact closed?

No. Replace relay.

Yes. Continue.

8.Is there continuity at the controller between the burner status terminals?

No. There is an open in the wiring between these terminals. Determine cause and rectify.

Yes. Replace controller.

FAULT CODE: Burner Hand

PROBLEM: The controller has not activated the burner enable output, but the burner status input is receiving a signal that the burner is on.

SOLUTION:Inspect burner control circuit. This fault has the potential to be a very serious problem. Close the manual gas valves immediately if the fan is not running.

1.Is the controller's burner enable output LED lit?

Yes. Close manual gas valves. There is a problem with the controller program. Contact factory.

No. Continue.
