Freestanding LPG boiler supplying heat and DHW to local public house........the vertical flue sits on the top of the boiler and goes through a 90 degree bend through the wall and is secure.
My question is.... what gap filler am I allowed to use to fill around where the flue sits on the boiler flue exit around the circumference where it has previously been sealed with a reddish silicone which needs replacing?
Thanks to those who reply.
