Hi,
I've also received a similar notice re proximity of balanced flue to overhead plastic soffits now that I've had a Gas Safety Cert check. There are no signs of scorching or any heat damage to the soffits even though the boiler has been in situ for 15+yrs, but I understand rules are rules.
Anyway, my question is - is it permissible to use Supalux boarding to neatly shield the soffit above the flue (or do I have to resort to an ugly aluminium deflector between exhaust and soffit)?
When searching the Net with this query I was surprised to only find one example diagram of a flue shield (using closure plate). I found lots of information regarding size of plate required based upon the distance of soffit from flue, and recommended air gap between plate and soffit - but little in the way of tried and tested designs (e.g. simple "shelf", upward sloping plate, plate neatly following the contours of the fascia/soffit)
Many thanks
