Stove flue - distance to brick

[cwhaley]

I'm putting in another wood burner in (this time in the kitchen) and have a question regarding the stove flue pipe. I only have a very shallow depth up the chimney flue (9 1/2") for the stove flue to go into.

Structurally, would there be problems if the cast iron flue from the stove was say 2" from the back wall? It is an internal party wall, so 9" two courses thick. I'm worried about the heat coming from the flue damaging the bricks/mortar. Gaps around and above the stove itself exceed the manufacturer's recommendations.

The first installation I did was signed off successfully and I didn't face the same issue I am here with distances.

I don't know a definite answer to this but can't help think that the heat from a pipe is going to do less harm to masonary than lighting an open fire in the fireplace. Was that not what it was designed for originally or did you build the "chimney"?

Thanks billabong. No the chimneys are original to the house and did originally have coal fires in them. Wish I could build chimneys!

I''m probably being pedantic, but the pipe is going to be much closer to brick than in the front room and I was just worried about heat - maybe it isn't a concern. All other distances are greater than requirements so it is just the flue.

Mine was signed off by bc although in scotland (presume very similar regs). In my setup the flue pipe that exits the stove is about the same distance from the back of the chimney, 2".

Higher up it's a liner that actually touches the masonary. That's only about 1m above the stove top so hot. It has never caused any issues and like I said, signed off compliant.

Hope this puts your mind at rest

It does; thank you. Unfortunately I'm one of those people who often let things like this stay on the mind at the end of the day after having done a job...

Both flue liners I have touch the masonry too (as they go up and around the 2 bends in the flue), so maybe I'm doubting the strength of it. Cheers, Graeme.
