Hi everyone,

on job now glowworm ultimate 50ff, got pilot but burner won't light, keeps sparking.

Replace gas valve & PCB but still no joy. got gas at inlet of valve. Nothing on burner test point, getting 240 on gas valve lead. Polarity good.

Anyone got any ideas?
Could it be faulty gas valve or pub? how can i test for this?

thanks
