Horizontal flue

[jim williams]

Hello to all.

I am building a brick smoke house but come up to a problem. (researched for ever)

The top end will be 36x36'' and I will dead end (top of brick walls) with a 3/8'' steel plate.

I want to build an arched top and exhaust out the back which will require some sort of flue.

Brick/ mortar with steel do not mix (cracking), thinking of some type of double/triple wall flue to run from damper to exterior with a cast iron door? would like to keep it low profile bend.

Please remit your responses. thanks to all of you.

Sincerely jim

Use High temp. stove gasket between the steel plate and masonry (let it float)...... Use a chimney flue liner, laying horizontal, to go through the wall....

Dave has a great idea there.  The rope will let it move and seal it at the same time.

Thanks dave and wes!
That was my original plans.
Just keep the brick off the steel plate by an 1/4" ?

Hey Dave, If I lay a flue liner sideways do they make an end cap for them? Also I would have to cut a hole in the side of the flue and it would just lay on top of my slide damper or heat silicone it down also?

Should I also lay loose firebrick (mortar will just crack up) over the top of the steel plate for heat loss? I am guessing so.

Hey Dave, If I lay a flue liner sideways do they make an end cap for them? Don't know....

Also I would have to cut a hole in the side of the flue and it would just lay on top of my slide damper or heat silicone it down also? What ever works....

Should I also lay loose firebrick (mortar will just crack up) over the top of the steel plate for heat loss? I am guessing so. I would lay insulation... No back fiberglass should do....
