When spark is present but there’s no gas, chances are the issue is caused by incorrect gas pressure, simply set your inlet-pressure at 11”W.C. with a minimum of two gas appliances running at the time. If you sense it’s due to low voltage, simply adjust the power supply to that of 10.5VDC. Other possibilities are listed as follows:

  • Main-burner tube is blocked – solution: thoroughly clean up the burner tube
  • E.C.O. wires or wires on solenoid valve are loose – solution: properly secure the wire connections
  • No gas flowing to the solenoid valve – solution: correct the gas supply

The following is when it’s the other way around: there is but spark is not present.

  • The electrodes which are attached to main burner are loose – solution: properly secure the electrodes
  • Improper gapping of the electrodes – solution: reposition your spark-gap to that of 1/8-inch and make sure it’s into the flame path
