Capped gas pipe by wood burning stove

    Just wondering whether it's okay to have a capped gas pipe in the fireplace with a wood burning stove?
    A gas safe engineer has capped the gas pipe and its sticking out approx 20mm above the hearth. It will be very close to where the stove is planned to be (a few inches at most), although the stove will obviously be on legs.
    I am dubious, but the gas safe engineer was adamant that it was fine. The pipe was capped using solder, and the engineer said the heat would have to be very intense over a period of time in order to effect the seal/solder, and that wouldn't happen just from the stove heat.
    I'm waiting to hear back from the HETAS engineer who will be fitting the stove.

    What's to stop you knocking it.

    It is at the back corner of the fireplace, so most likely to be near-ish one of the rear legs of the stove, so unlikely to be accidentally knocked.

    We can't easily cap it further back in the supply, as the pipe runs under the concrete for about a run of 6 meters.

    I certianly wouldn't be happy with it's location, but I don't do gas.

    No :-(
    The gas safe engineer made me feel like I was panicking unnecessarily, but I do feel concerned.

    If it had to stay I think I'd box in somehow or protect it with a fixed ornament for protection

    Probably nothing in the regs preventing this but i would endeavour to avoid.
    Gas burners are sometimes just inches from live gas pipes.
    Is it not possible to locate the tee piece from were the fire supply started.

    It will not get hot enough to melt the solder unless it is actually in the flames. If you are still worried change for a compression cap.

    We have a similar situation although the old gas supply is just off to the front.

    It never gets that hot underneath the can easily keep your hand there. Definitely not hot enough to melt solder!

    Soon as you mention working on gas all the gas safe people say make sure its done by a gas safe fitter. Well you have done that, so hopefully these gas safe people know what they are doing.

    If you're worried, pop a thermometer next to the cap whilst the stoves on and see what it heats to, as long as it's under 220 DEG C (Melting point of solder, and I would put money on that it will be) then it'll be fine. Plus The pressure on domestic gas is extremely low so even with heat addition you're not going to increase pressure enough to pop joints anywhere.
