Looking to install a flue for a warm morning stove. the existing hole is too low to place the pipe in.
1) Whats the procedure to go through the existing brick?
2) what sort of fitting do I need to install in the hole once I make it? Clay or Metal? The long term plan is to place a boiler, should I make it 8"?
Thanks

Hi bud, I'm no mason but I like to get dirty so I'll give you my thoughts.
first my neighbor has an AA130 boiler in his basement and it has a 6 inch pipe installed by an experienced coal guy.
I accessed my clay lined chimney with an inexpensive chisel and hammer...don't forget the safety glasses and leather gloves incase you miss.
I was fortunate that the hole was fairly close to the 6 inch pipe, I sealed the pipe with fiberglass insulation for a snug fit.
A coal boiler or furnace is a more permanent install so a clay thimble might be a better option for you. You can chisel out the hole and put the thimble in place resting on fresh cement and seal the sides and top with cement, either trowelled in or for lack of a better word, "home made pastry bag" made with an old pillowcase with a corner snipped off

The new thimble should be clay. Remember it needs to pitch up into the chimney!

In case the boiler you choose to install requires it.

diamond cut off wheel in a Harbor Freight 4-1/2" right angle grinder is a breeze.
lay it out like cutting a pie and use chisle to knock out the wedges...smaller pieces of pie break easier.
shop vac for dust control

Good Idea! Still not sure what sort of boiler I'm gonna end up looking for. Originally I was really into the hand fired units. The more I hear from people and read about stokers the more I lean in that direction. In the meantime the Warm Morning will go there.windyhill4.2 wrote: ↑Mon.

I hadn't thought to do that. I'll have to take a look out in the garage I think that's what I have! https://www.harborfreight.com/4-12-in-5-amp-heavy ... 60372.html That's the one I have.

I'm not positive but believe a 6" will slide into an 8" if you go big and need to reduce it. Ideally the thimble should be the same size as the breech on the appliance. A clay thimble is about $20 at the brickyard.

There is also 8" to 6" reducer pipe. I have a very strong draft so it shouldn't affect things much.

Or--just pack it with insulation & put a cosmetic ring on it. Yes, 6" will go in a 8" thimble.
