Hi, I,m new to the forum, I have a Boulter Economy oil boiler with a Riello burner .The boiler fires up no problem and runs fine for approx 3/4 of an hour but then begins to pulsate and eventually stops completely.Can anyone shed some light on this problem.

Inner flue pipe seal on Balanced flue failed try running it with the front cover off if this clears the fault then the flue pipe needs to be removed and resealed DO NOT OPERATE THIS BOILER FOR A PROLONGED PERIOD WITH THE FRONT COVER REMOVED - this can be hazardous to health!!

Tried running the boiler with front cover off seemed to work fine ,when the cover was replaced after a while it started to pulse again,so I will get the flue seen to as soon as possible as you suggested.Thanks to you and Spraggo for your prompt reply and good advice.
