  • Vent roof?!?!

    Hi All,

    I'm wondering if the vent roof where it joins the flue needs to be constructed of fire brick/insulating concrete or can I use a section of sheet steel bent into the shape of the arch and attached to the brick arch with fire cement?

    I think it will be OK or will there be issues with the steel expanding from the heat and then cracking the fire cement?

    Thanks

    Rob

    You can in fact make your entire entry/vent out of metal. They do expand at different rates, so you may want to make your masonry/metal joint somewhat flexible. Most people use some kind of masonry anchor and bolt as the interface, instead of a rigid mortar.

      Great, that's just what I wanted to hear!
