Clearance to combustibles versus masonry

[Wyodaniel]

I wind up looking at so many articles on here, I figured I would finally just create an account.

I'm trying to get a wood stove installed in an alcove in my basement, where there used to be a pellet stove installed. I have an older Quadrafire 3100 ACC that I would like to put in here. My concern is the distance from the side of the stove to the side of the alcove it would be partially in:



The installation information on the back of the stove calls for 13" clearance to the side. If I put this stove in here, I would have 7.25" clearance on each side. However, that would be the distance to a wall that is composed of tile directly over the cinder block wall of the foundation; it's all masonry, which I don't believe counts as a combustible. The nearest combustible material would be 18.25" on each side of the stove.

Can I reduce the clearance when it's going up against masonry, or is that not how it works? I can tell you what the guy from the stove store says, which is that it isn't allowed and I need to buy one of their new $4000 stoves that has different clearance requirements, but I wanted to ask on here.

Thank you!

That's correct. Clearances are to combustibles. If there is no wood behind anything there then the clearances don't apply or they are only to the nearest wood. Just be sure that it's all cement block behind the tiling. Also, the ceiling clearance (G) still needs to be honored.

Yeah, I know exactly what's behind all the tiling since I did it all myself. This is what it looked like a couple months ago, with a defunct pellet stove:

I guess my final question is going to be on the chimney; the pellet stove exhaust was 4", which went through a giant reducer at the ceiling (you can see in my first picture) to fit into what the stove store guy described as a "prefab pipe" that is 8"~ in diameter. He said that I need to get a 6" liner put through the existing pipe to connect directly with the 6" pipe coming off the top of the wood stove; does that sound accurate?

With walls that close, consider a fan to move the heat away from the stove into the room.

Are there side walls tile over block as well?

Correct, everything is tile adhered to cement.
