Flue through a timber wall

[Scott_D]

I'm going to fit a new combi and the flue will go through a timber wall
Its a standard telescopic horizontal flue (Worcester greenstar 30i)
Do I need to do anything differently? Sleeve the flue?

Thanks 🙂

Where the boiler is to be fitted to a timber framed
building the guidelines laid down in BS5440: Part 1 and
IGE "Gas Installations in Timber Frame Buildings” should
be followed.

Basically make sure you not cutting through anywhere where will affect structure.
Fit flue within a metal sleeve with 25mm gap. Seal gap with flue jointing compound etc.
Thats the bones of it unless MI's give specific details.

Either cut back the gyproc and frame around where the flue is passing through with noggins and line with superlux or cement board and reboard or use a 6" sleeve metal or supersleeve (clay drainage pipe) or just do what everyone else seems to do and don't bother.

Thanks all. The extension isnt built yet so not sure how it will be constructed.
I will get my books out and have a read
