3. Push power switch ON and immediately touch one end of the jumper firmly to the GND terminal on the
module. Do not touch the jumper to the SPARK terminal, but, move the free end of the jumper slowly towards
the SPARK terminal until a spark is established.
Pull the jumper slowly away from the SPARK terminal and note the length of the gap when the sparking stops.
See table below for results and action to be taken.
ARC LENGTH ACTION
No arc or arc less than
1
⁄8". Verify power at module input terminal.
Replace module power is verified.
Arc
1
⁄8" or longer Voltage output is ok.
If you are getting spark but the spark continues after the pilot is lit check the following.
4. Check for ground wire and ignition cable continuity.
5. Check that flame rod is clean.
6. Check for crack in ceramic insulator.
7. Check that pilot flame covers rod and is steady and blue. Adjust pilot or pilot flame if necessary.
8. If the above are all in good condition replace module.
PILOT CHECK (Pilot will not light)
1. Check that all manual gas valves are open, that supply tubing and pressure are good and pilot orifice is not
blocked.
2. Check electrical connections between module and pilot operator on gas combo valve.
3. With volt meter check for 24Vac across PV-MV/PV terminals on module. If voltage is good replace the combo
valve. If voltage is bad replace the module.
BURNER CHECK (Main burner will not light)
1. Check for 24Vac across the MV-MV/PV terminals. If voltage is bad replace the module.
2. Check electric connection between the module and gas combo valve. If good replace the combo valve.
3. Follow steps 1-4 under Removal of Burner and check for clogged burner ports. If clogged use a small probing
device to open the port.
