Basement woodstove, backdraft, carbon monoxide

[BarrelStove69]

The Pacific Energy stove that's shown was a good one and much safer. This one is old, but the design was solid and parts are still made for it. What is its condition internally?

The idea proposed is ok, but with a major caveat. Stove pipe can not pass through the room envelope. In order to do as planned, it must be chimney pipe that goes through the roof and upstairs floor resting on a ceiling support box in the main floor ceiling. This means that the existing upstairs chimney support may need to be replaced.

As long as the clearance requirements are honored, there is no need for additional wall shielding.

PS: Looks like a really nice home.

Forgive me for sounding clueless.

1. What is a room envelope.

2. Can I get some clarification on why it would be a big caveat? Chimney pipe would be fine if that's what has to be done - would this be super costly? I understand the main floor ceiling would need a support box - but why would the other one have to be removed?

This doesn't seem like too much of a caveat to me if I understand correctly.

Just supposing here. What is at the main floor interior location of the exterior chimney pipe that connects to the basement stove?
I'm thinking another option would be to raise the tee to the first floor and run it through a thimble at that location. Then connect the PE stove there. If possible that might be a much less expensive option if the PE stove is in good working condition.

That interior location is our office room. Its pretty closed off from the rest of the main living space.

Husband thinks that if we put a stove in there we would have to start tearing walls down to heat the main floor adequately.

He's right. The stove is an area heater. It belongs where the heat is most needed and welcome.

I figured as much; if we're going to start cutting holes and reconfiguring thing we want to do it in a way that makes the most sense!

Good questions.
1) put another way, stove pipe can not pass through a wall, ceiling, closet, or attic. It can only be used within the room.
2) The existing support box is known as a cathedral ceiling support box. It has a few functions. It maintains safe clearances, it supports the chimney pipe, and it acts as a transition between chimney pipe and stove pipe. This last point is important in this case because it means that another length of chimney pipe can not be attached to the bottom of the support box.

The current basement chimney pipe, if in good condition, could be removed, roof patched, and relocated.

More supposing here. I have not seen this done, but I am wondering if the bottom of the current upstairs support box could be cut out. Then, a new ceiling support box be installed, centered below it, and the current cathedral support box (now open on the bottom) extended to the floor level to act as a chase for the new chimney pipe installed to the new ceiling support box. bholler, any issues with this?

It should work fine

Great. Given the age of the PE stove, if its connecting pipe is the same age, I'd replace that chimney pipe with new. It's likely is decades old and could be hard to impossible to find mating pipe now.

Barrelstove69, can you post some pictures of the interior of the PE stove?

I don't know but if you have a reputable dealer/installer in the area I would spend the money to get them involved. They should be able to give you suggestions on placement, installation and your WETT requirements and your inspection. The last thing you want or need is the insurance company not covering the job.

7"

Is it a 6” or 8” chimney? The fact there was a wood chute should clue you in to how much wood it will consume!

I would investigate the possibility of moving the new stove up to the main level.

I think that's the plan! Really hoping we can figure something out before next winter season.

Here are the photos, as per request!

It looks barely used. Run properly it will last for many years.
