the ignition controller.

2. Start the burner.

3. Jumper F-F terminals on the

ignition controller.

Does

lockout?

Replace ignition

controller.

Measure resistance

across cell leads (F-F

terminals on the ignition

controller).

Is resistance

zero?

Correct short

circuit.

Is resistance

greater than 1500

ohms?

Open transformer and

clean cell face and seat

firmly into holder.

Is resistance

greater than 1500

ohms?

Is the over fire

draft correct?

Is the CO2

correct?

Replace the cad

cell.

Adjust for

proper CO2.

Adjust barometric

damper.

Cad cell and ignition
