Hi, I've just bought a Vaillant Condensing combination boiler which
I'm going to install in my loft. I've got a vertical flu to go through
the ceiling, but the combi is to be mounted on the chimney breast in
the loft so the flu will come up next to the stack, only about 250mm
away from it.
In the instructions is says that the flu should be 500mm from a
parallel wall (put doesn't say anything about a chimney). Does anyone
know if this distance is to do with the operation of the flu or just
because the fumes may discolour the wall, in which case it doesn't
Also, do I need to fit a trap to the 19mm condensate drain before it
connects to the sink waste in the bathroom?
Any assitance would be appreciated.
