I bought a Flavel Misermatic gas fire in Nov 2004 and had it fited by a
gas engineer. It worked ok for about 6 months and then developed a
fault. It would work ok for a while and then start making bubbling
noises in the flames before going out. This only happened on full power
and not on half power We would have to wait about 5 mins before
The guy who fitted it would not come out and the shop where I bought it
went out of business. After many enquiries I made contact with the
manufacturers as it was still under warranty. They sent an engineer out
who turned it off and went awya for 2 weeks (he ordered a spare part).
We had to hendure 2 weeks of freezing temptures. He return and replaced
one of the ceramic plate (which he had broken) and nothing else. So we
waited 2 weeks due to his fault though he made it look that the gas
fire needed another part.
Anyway, he could not work out why the gas fire was going out. Just by
co-incident I turned on the hot water; this dropped the gas pressure at
the gas fire. He homed in on the problem; the combi boiler was causing
the problem. He went and looked at the boiler and said that the piping
to it was wrong. Apprantly, the combi boiler had 15mm gas pipe going to
it which was not enough. So when we turned on water, the boiler was
taking excessive amount of gas and the gas fire was being starved of
He offered this explanation and left saying that our boiler was to
blame. The gas fire worked ok for 3 months. It has started to go out
again now after 3 months.
What I do not understand is that the gas fire worked perfectly for
first 6 months although we were using the boiler constantly for CH and
hot water. And again after the engineer had been, it worked ok for 3
Did the engineer give me incorrect info? Is the 15mm piping to the
combi boiler incorrect (I am not even sure what size it is - boiler has
always worked and BG cover it for service)? We never had any such
problems with previous gas fires.
