Question about flue pipe on a wood burner multi fuel applian

[davyboy10]

I am just about to buy a wood burner dual fuel appliance. The flue outlet connection is 5 inch and I want to run an external flue outside and up the wall so that it is 1 metre above the roof line. The cost of the flue for the appliance is ridiculous and so what I need to know is would an 8 inch internal diameter selkirk twin wall be ok nfor the installation. I als have a cowel for the twin wall but I just need some advice.

When i spoke to the shop they said selkirk would work but I didn't tell them it was 8 inch internal diameter. Obviously I would need a 5-8 inch adaptor as well. Any advice would be most welcome.

It does however depend on equivalent length write to manufacturer with all facts and ask forwriten response. If you don't get consent in writing thin ice.

solid fuel chimneys must meet BS EN 1443 standards.

I very much doubt a cheaper alternative will be acceptble as the materials used for solid fuel are of a much higher grade to resist the corrosive properties of solid fuel gases.

There should be a performance designation code on the product similar to the following: T400 N2 D 3 G 50

If you can find this infomation and post it here i can let you know if it's suitable.

Also don't take solid fuel for granted. When burned correctly it produces a far greater percentage of CO than any other heating fuel (12,000+ PPM) so make sure you get it right.
