I don't think there is enough clearance

[NotAProfessional]

Hey,

Sorry if this is not allowed, but I recently bought a house where I think the stove might have been installed improperly. The reason why I decided to ask this forum is because I've been trying to get a contractor come look at it for months now, with no luck. I'll keep trying, but time is running out, especially if I need to make a decision on what to do.

I believe it's considered an alcove install, which is allowed as per installation manual, but I don't think it meets minimum clearance.
The stove is called Century Heating S250.

I added some pictures below with distances to the closest wall as well as screenshots from the manual.
There is wood behind the corrugated metal, which is the closest combustible material. Pipe is double wall. The alcove would be fine with ~21", but I'm not so sure about the face, since it's only ~11".

I'm wanting to replace the metal with some sort of brick, but since this would decrease distance even more I'm hesitant to do so. I also have to redo the chimney chase on the outside, because it's leaking. The busted through the wall of the house and added the chase to the outside, but there is no fire stop or anything. So cold air is leaking through the "ceiling" in the winter.
The stove has definitely been used before, so it's not a brand new setup, but that doesn't mean it's right or safe. Any pointers on how to approach this would be much appreciated.

Fly this one by SBI support. If this install is with their AC02762 heat shield, and if the heat shield is properly installed, then it might be proper. However, The heat shield does not look like SBI's kit and it doesn't look like it has the proper air gap at the bottom. Is the alcove ceiling at least 72" high? If not, that's also a fault. Switching the heat shielding to brick would defintely not help.

No heat shield. They used corrugated metal as "heat shield". Which I guess is supposed to create an air pocket between metal and combustible material.
The alcove is 72" high, yes.

The intent of the corrugated metal is heatshielding but it doesn't appear to be properly installed and if so, not acceptable. Is it on 1" spacers and open top and bottom by at least 1"?
SBI has only certified the reduced clearances with their tested shielding. It's not clear from their docs if they accept it in an alcove. Call SBI support for clarification. If accepted, then replace the corrugated steel with SBI's shielding.

It has fire-resistant drywall between metal and wood. And yes, I do have 1" top and bottom
Okay, thanks. I'll reach out to them.

I assume my only other option (besides reaching out to them) would be to make the cutout bigger? Which equals to cutting a bigger hole in my house lol

Is this shielding on 1" spacers? If so, let SBI know that there is NFPA 211 wall shielding installed.

No, sorry. My last comment wasn't clear enough.
It's wood, fire resistant drywall and the metal is directly screwed onto the drywall. No spacers between drywall and metal.

EDIT: I assume they thought since the corrugated metal is "wavy" it's enough to be counted as 1" spacer

EDIT EDIT:

I think this is what they were going for, which would only apply to NON alcove installations I would think?
