I've just purchased a vertical flue kit - Worcester Condesate II - I don't see anything in the kit that provides protection against the duct passing through the combustible roofing material i.e insulation,osb board then roof membrane.
What do i need to give me this protection.Is there a metal sleeve or something i need to purchase?
It would seem i need a firestop plate - 100mm internal diameter - but in two halves so it can form an oval shape to fit round the flue pipe on an pitched roof.
