If erratic ignitor operation is experienced check for the following:
1. If you are experiencing system lock out reset system by turning power switch off, wait several minutes and
turn switch on.
2. Check for good metal to metal contact between the pilot bracket and main burner.
3. Check that all lead connections from the ignition module to the ignitor system are solid.
4. Check that GRD (BUR) lead from the module to the pilot burner is solid and that there is not any damage
to the wiring. If damage is detected either replace the ignitor assembly or the ignitor wire with no.14-18
gauge, moisture-resistant, thermoplastic insulated wire with a min. 105 degrees C (221 degrees F) rating.
5. Check the ceramic flame rod insulator of the ignitor for cracks or evidence of extreme heat. If one or both
of these conditions are found replace the pilot ignitor assembly.
6. Check to insure that ignitor boot is not loose or damaged.
If the above visual checks are positive the following checks should be preformed using a jumper
wire and voltage meter.
WARNING: WHEN PERFORMING THE FOLLOWING CHECK DO NOT TOUCH THE STRIPPED END
OF THE JUMPER TO THE SPARK TERMINAL. THE IGNITION CIRCUIT GENERATES
OVER 10,000 VOLTS AND ELECTRIC SHOCK CAN RESULT.
NOTE: You will need a short jumper wire made from ignition cable or other heavily insulated wire.
1. Close the manual gas valve
2. Disconnect the ignition cable at the SPARK terminal on the module.
