Thanks again. Is it possible that if the ignition gas pressure is currently set below 13 mbar (as you suggest could be the case), it would light normally when the ambient temperature is high, but with a cooler temperature, a resultant slight drop in pressure is therefore sometimes causing the...
Thanks for your information. Is it therefore possible for the boiler to have problems igniting at low, but above freezing temperatures, yet to work normally when the temperature is say 10 degrees C?
My Ideal combi boiler on LPG seems to have an ignition problem! The ignition procedure runs as it should, but on some occasions the gas fails to light. The problem only seems to occur when the outside temperature is pretty cold, perhaps low single figures. After repeated re-sets it lights and...
