Hi, Before the house blows up can anyone tell me what is causing the "exlosion" in my boiler on flame-up!
I recently came home to find the pilot light out. I checked it and it needed a new assembly as the pilot flame guide had disintegrated after 15 years. The relacement was easy and I serviced the boiler at the same time. checked for leaks with a radio-active sensor leak detector. OK.
System fired up beatifully and works well...........BUT. if switched off for a long time there is an ear shattering bang when it fires up!
HELP
