Clay liner

[richardwale]

I live in a 70's house with a clay liner. What diameter are the liners, I'm thinking probably 6 inch but was curious to know if it was bigger could I drop a new steel liner down inside?

Mate has just put a burner in his 70s house . He could not get liner down as clay was also 6 inch. He just pushed s/s liner inside about 4 inches Into first clay liner just above mantle. seemed a bit dodgy. But my clearview fittings are loose fit . They said no need for fire cement or the like, as air would only leak in a bit and would not leak smoke out. Which it does.nt. something to do with pressure . As a bricky for 25 years I've built many a stack in the past with. 9 inch internal liners. So hope fully you have these and can slip a liner down.or maybe a spigot of type maybe bought to join to 6 inch clay.

Cheers. Is there any way of telling? My current burner is attached to it via a 6 inch flu?

Sorry bit confused.is your stove pipe already connected to the clay. Or is it inside the clay

We live in a 70's house and the clay liner is 6 inch. Couldn't get a 5 inch liner down it when the stove was fitted; one bloke nearly fell off the roof trying...

My clay liner was 7.5" and a 6" flexi was a good snug fit . I was lucky I suppose .

Stubby, how can u tell the liner diameter if a stove is already attached? Or is there not a way to tell without removing existing stove?

Errm ... Think you will have to pull the stove out the way to measure or get on the roof maybe ? Don't know any other way unless there are similar houses ( built by the same builder at the same time ) who don't have a stove and would let you in to have a look ??

Usually if round they are 7, 8 or 9 inch. There are also square liners of similar sizes. You will want 2 inches of clearance to stand a good chance of getting a flexi liner down. If you have a 6 inch clay lined flue you cant put a flexi liner down as the minimum flexi diameter is 5 inch and that can only be used with Defra approved stoves with a 5 inch outlet.

 

Cant say that I can remember ever coming across a 6 inch clay lined chimney.

Most of the clay liners I have looked at for stove installations

Have been fitted upside down ie sockets downwards
