I'm constructing a corrugated PVC lean-to on my outside wall, but my existing boiler discharges hot flue gases just beneath where the new plastic roof will be. Is it possible to buy a flue extension kit for my boiler (a Potterton Profile)?
always possible to get extension kits, but you MUST NOT fit this yourself as it can effect the boiler and must be installed and checked by a competent person
