Combi boiler with rear flue

[woodsy]

Here's a section - excuse the scribbled "computer writing". The flue is just long enough to give a tightest dimension to slate of 300MM

cant have the flue protruding by 300mm anyway - unless they've changed it, then no white of flue to be showing.

that cant be accurate!
the flue on the vokera rear extension cannot be cut down less than ''375mm'' i think it is?
that means there will be white showing on non-cavity walls!!

Good point chaps. Think it's been decided that the flue can't go where he wants it anyway

Being told previously by Vokera tech that the white is not uv rated and will rot over time if in sunlight but may have changed.

wondered when someone was going to pick up you cant use a horizontal flue to go out through slate roof....

best advice would be to get a fresh set of qualified eyes on the project and mount the boiler somewhere else where it can be serviced and installed properly.
