Gas fire with liner possible

[b21playa]

Hi all

Looking to get a gas fire installed in an unused fireplace…there was a plug there for an electric fire. It has a solid rear panel, and cutting into this has revealed a liner (guess it was used before at some point). I’ve had the liner swept and checked but before moving forwards and getting a gas man in I wanted to check this is suitable to be used with an inset gas fire. The liner come all the way down to the hearth and sweeper thinks it could have been used as a rear exit on an old fire.

Any advice welcomed, don’t want to start spending money for no reason or turning into an expensive job for now

Thanks

Onset gas fire is wasteful of gas. Look at the fire spec. Look at the input rating and the output rating. If the fire is a poor performer, only out put figure will be given. A high efficiency inset fire will be expensive but will be 80% typical efficiency

What do you suggest?

I was thinking of a gazco logic he which I should have mentioned I have from my previous place where chimney was removed…been sat in garage for a while. I think this was 89%+ efficiency…same as my valour home flame harmony that I have in another room.

Good to go with that efficiency

Manufacturers instructions and or building regulations and British Standards will tell you if a liner is suitable.

Not sure what you mean by a liner - usually a liner would be considered to be a S/S pipe set into a vertical chimney and then run upwards to a terminal on the roof. Just when you mention old fire may have been a rear exit, we're not talking about a balanced/fanned rear flue that will exit out the wall?

If not and it is a vertical flexi liner up to a terminal on the roof then it needs to be a certain size, a certain material type and needs to be sealed top and bottom with the correct terminal. Older liners/terminals may not be. Your gas chap will be better placed to survey and say if the current installation is suitable for gas.

Sorry should have said it’s a stainless steel pipe that’s attached to a terminal at the top abut is left loose at the bottom (behind back panel). It’s not a balanced flue as the chimney adjoins the dining room which had a stainless pipe in as well that was connected to an old floor standing boiler. This was removed a few years ago when I upgraded to a wall hung condensing boiler.
