BURNER FAILS TO IGNITE:
Make sure propane tank has fuel and valve is open. For natural gas generators make sure gas supply is "On" and shut off valve is open. Make sure propane tank has not been overfilled. If so, take tank outdoors and open valve to release gas for a few seconds and reconnect. Be sure all air has bled from the hose and gas is present. Check that transformer is plugged into a working power source. Make sure power indicator switch is in “ON” position.
Check to see that nothing is interfering with igniter probe. It may be necessary to adjust location of the igniter to the burner. The spark probe should be 1/8 inch above the burner and approximately 1/4 inch in front of the slant of the burner slot.
BURNER WON’T STAY LIT:
Check that gas supply valve is open enough to support a strong minimum flame. Check timer and power source operation.
FLAME BURNS IRREGULAR:
Dirt or residue could constrict burner orifice. Low fuel pressure due to depleted or contaminated fuel supply. Lack of oxygen content in room due to inadequate fresh air intake. Excessive air movement or gust from fan or ventilation. Generator not setting level. The flame should be a strong blue color about 1/2 inch high. Flickers of yellow are normal however constant yellow tips indicate improper burn. Contact Green Air Products service department for solutions.
BI-PASSING a busted switch. You don't really need the switch so rather than replace it just omit it. See diagram.
