I have a CSI 85 & on the front panel a light has come on in dim red with a picture of a flame & what seems to be a temperature gauge,which is overheat & or flame failure I can hear the pump running but it's not lit. Is there a way or relighting the boiler is the whats wrong that the pilot has merely gone out or does this indicate a problem of some kind? My wife & kids would appreciate your help on this...
