Probably. Flue liners are different specs for just abouyt every fuel/fireplace.

I would recommend it.

Pass. Don't do gas,. What gas? not seen it in 30 years.;-) Must bne in them new fangled 'towns'

IIRC its about 8" all round of non combustible.

Pass.

Very unlikely, there is no requirement for a liner for a gas fire.

Hmmm, perhaps I confuse what is a liner with what is a flue, but I understood that for most recent fires (I'd guess mine is from the

All chimneys were "lined" (or should have been). If the original mortar lining was in reasonable condition and the fireplace passed a smoke test, it will have been deemed suitable for a gas fire. It will probably be suitable for a coal fire and maybe a log fire too if in good condition but logs are cooler and tarrier and may require a new liner, which is, generally, a stainless steel tube.

Its in Building Regs part J(?). I thought 150mm at sides and back from combustible material/wall (i.e. nil clearance to brick) and the hearth must extend 150mm each side where the fire projects into the room. I can't remember the hearth projection at the front but at 300mm you would have to be very careful to avoid cosmetic burns to floor coverings when fueling.

Thanks - I think I'm OK then. The kind of old stove I'm looking at is wide but not very deep, has no front doors and loads from the right hand side where I should have enough space.

behind will be tiled so clearance there can be pretty small, if I read you correctly

What does this mortar lining look like? I've never seen anything other than bricks when I've peered up or down a chimney.

Just a thin layer of render on the face of the bricks. It generally is the source of all the anonymous lumps of mortar that fall down the chimney behind a gas fire! An previous house, built in the 1920's had a gas fire and then a real fire fitted by me and we decided the liner (or perhaps lining is a better term) was OK.
