Hi all, a question on a chimney. I started a build for an oven and after getting the base done and when I was about to start on the dome, I was offered a poured refractory concrete dome from a friend to drop into place to speed up my build.
Unfortunately the dome comes with a chimney... at the back, which I know is not the design that is recommended. To the credit of the guy who poured it, it is 1/3 the way down the back of the dome, so at the same height of the door entrance.
I estimate I can plug the chimney with firebrick, mortared in with high-temp mortar, and extend the entrance a little to add a chimney; When I insulate and brick over it, it should just seal it up.
Otherwise since the chimney is 1/3 the way down the side of the dome, if I 'plug' the door after I light the fire it will still get a roll on the fire around the dome before the heat goes up the chimney... although I'm not sure this will work.
Any comments, or suggestions for those who have had to deal with this issue?
