ive got a ravenheat csi 85 when i switch on, the pump runs, the fan runs, and the igniter clicks but it does not fire up, after about 1 or 2 mins it shuts down and an orange indicator with picture of flame lights up. pressure is 1.5 bar
first check you have a gas supply to boiler
check if other gas appliances are working
is the gas cock open on the inlet to the boiler
does the pcb supply a constant supply to the gas valve?
