Out of interest does anyone know how far away a gas pipe for an old gas fire needs to be from a log burner?

I have pulled out an old gas fire and it looks like the pipe just goes into the wall and I can't trace it back to where it meets the main gas pipe that is in the kitchen. We are having a new log burner installed and don't really want the plumber to pull up the lounge carpet and floor to dig out the pipe. So wondering when it is capped off how far away the pipe needs to be for the stove.

Don't worry I will not be doing this myself.

Don't know on official distance but our gas man capped off the gas pipe barely a couple of metres away from where the stove is now. It runs under the floor boards which were bare at the time so no bother.
If he can be confident on where it connects in the kitchen I suppose he would chop it there.

As above - why not cap back in the kitchen and be on the safe side?

Don't know if it does meet in the kitchen or not. The main gas pipe comes into the house under the kitchen where we have a gas hob. I assume it connects somewhere there but don't relish pulling up the wood floor in the kitchen, hallway or carpet in the lounge. Just wondered if it could be capped and buried in the wall by the fire place

Ah sorry, misunderstood - thought you meant you could find the connection in the kitchen but didn't know how it got from there to the fireplace...

no minimum distance in hetas/gas or BS regs . Good practice is to make unused spurs as short as possible..ie non existant.

the soldered fitting would melt at approx. 180 c? will your wood burner be hotter than that.

I would have thought 6" horizontal separation would be fine, you're not going to melt the pipe unless it's touching the fire.

mines buried under the hart, about 2ft away from the fire. Works undertaken by a Gas Safe engineer/HETAS fitter.

Gas pipework has to be able to be purged of air to ensure safety, therefore caps need to be removable.

Problem is you are not allowed to conceal compression fittings beneath floors.

Best to cap off and remove the dead leg altogether

I would want it capped well away from the log burner myself. Maybe belt and braces but thats the way I see it.

Bear? You sure? I thought compression fittings were not allowed on gas pipework and the fitter I use who is very good in all regards used a soldered on cap on a spur.

They're allowed if accessible, are they not?

Soldered caps aren't allowed on a dead leg as the pipe cannot be purged. Compression certainly not allowed in a void such as below a floor.
