Gas fire mystery problem

[Steve W]

Hi all,

I'm a member of the public with a persistent problem with a gas fire that's been looked at a couple of times and is still not right. I'm not looking to repair it myself but just want a bit of impartial input before I spend any more on it!

Basically it's a new (less than one year old) gas fire and it's a stored gas version as we have our gas in a tank outside. The problem is that it lights up fine but it will then cut itself out anywhere between 15 mins and 2 hours later. It was first thought that a new interupter would cure it (my baby son had pulled the wires out of the other whilst the fire was off!). That didn't work. Then we had all the logs taken out and replaced and the whole thing hoovered out. That hasn't worked either. As it's new, I don't know what else could be wrong unless it has a fault caused during delivery or manufacture etc

Does anyone on here have any further ideas for what it might be before I get another engineer out or get on the phone to the manufacturer?

Thanks in advance.
Steve

It probably has two safety devices - an oxypilot and a TTB switch (thermal switch). The oxypilot will shut the fire down if the oxygen level in the room is reduced (it doesn’t monitor CO). The TTB switch will shut the fire down if the flue gasses aren’t going up the flue correctly. The times it’s going off at could indicate a flueing issue so it’s really important to have it checked over again and not to use it in the mean time. If your flueing and ventilation check out ok it’s probably a faulty gas valve or loose connection in the thermocouple circuit.

Hi Waddycall,
Thanks for this. Those are very helpful suggestions that I will mention to the engineer when he comes. We've had the flue checked three times: once before the fire was fitted, again when it was fitted and finally when the interuptor was replaced so I don't know if it can be that. Hopefully, it's the faulty part but we'll soon know.
Cheers,
Steve

It could also be a partially blocked pilot (if the fire has one that is).
Obviously this can only be dealt with by a Gas Safe registered person with the Gas fire ticket!!
You already know that but I felt like I should say it anyway.

I know the other guys are thinking flue-ventilation problem , But just a thought, a shot in the dark, has the jets been checked to make sure they are LPG ?

TBH, I have never seen a fire with both an Oxy pilot AND a TTB. This fire has a TTB. Otherwise I agree.

If NG injectors are fitted,there would be a very disappointing flame picture. But I have learnt over the years that anything is possible

OP: I asked if the fire is built into an opening or against a flat wall/chimney breast. Any chance of a picture?

Keep an eye out for situations when it misbehaves ..more clues .
Any other gas / ethanol gel devices operating in area, at same time it happens .
What are outdoors wind conditions ... Still / gusty ..blowing steady + direction.

has the chimney passed a flue flow test?

Why is this thread still open and being replied to
He's (by his own admission) not gas safe, so why are we helping a non GSR break the law and possibly put his and his families life in danger
FFS mods, get your act together
Are post counts and traffic more important than safety???
