mark said: (quoted from post at 08:11:34 09/14/07) I can't find a block layer willing to build a flue for me, so I am going to do it myself. The problem is, I've never done it before. I need to know how the liner is installed. Does it sit on angle iron, like a lintel, inside the block? How do you cut a nice clean hole in the liner to slide the round flue pipe in it? I ran a search and found lots of nothing! Any suggestions? |
Concrete/cement or clay flue liner? Start the flue liner atop the smoke shelf, not on angle iron, (expands at a different rate).
Use 'fire clay' mix in the firebox and between liners. Also parge the interior of the 'smoke shelf', for a smooth transition/flow.
Don't understand why you want to slide flue pipe into the liner????? but, use a saw if you want, how big of a hole? Use a 4" grinder / a diamond or carborandum blade. Take your time.
I have downloaded County ordinances (diagrams) of chimney construction. As the man said about the foundation..... .listen to him, he's right. It's not pressure it's also about mass.
We grout ours solid on here, it's a rebar/earthquake thing, You do like you want, I've seen where critters can make they're homes there too.
....sl, been there, did that, use zero clearance now....
