stack support

[The Butcher]

I have built my cinder block arch. It is three bricks high. I am trying to get the stove pipe in the second layer of bricks with one layer on top. I am having a hard time getting the pipe to stay put.

What have people used to get it to stay? I am tring to get it as long as possible to create more draft, it is about 10ft now.

Thanks for any help.

My stack is about 14 feet high, I support it with a 1 1/4" steel pipe anchored in concrete.

The bracket to the stove pipes is attached about 8 feet off of the ground.

The support pipe threads into a union at the base so I can take it down when the season is over.

Hope this helps!

One way to get the base of your stove pipe connected to the arch is take a duct transition for a floor register and reverse the flow direction.

I have used this with the rectangular outlet beween the brick courses of the arch and the round part pointing up for the stack.

OKay John Thanks.

I looked at your pictures and got a pretty good idea on your setup.

I want to be able to move my entire arch after the fun is over.

I put a 2x4 about 18 inches behind the stack, with the base in a block and supported by ropes to other blocks. Use galvanized wire around the stack and back to the 2x4 to support the stack.

My first evaporator I had the stack supported by guy wires. I used a steel band (plumbers strap) in 3 pieces, each bolted to the next to form a ring around the stack with a tail or tab sticking out at each bolt. To the tabs I hooked my light wt steel wire cable (about 1/16" ) and anchored it to things on the ground. The band fit tightly around the stack. This worked well for my free standing back yard rig.
