Stove Clearances

[richas]

Hello,
I am installing this stove in a small 10x20 bunkhouse:

US Stove 750 sq. ft. Tiny Wood Stove, 75% EFF TH-100 - The Home Depot

Make your wood wall look new and attractive by applying this Unbranded US Stove ft Tiny Wood Stove.

I am installing it in a corner, on an insulated/tiled pedestal, with 1" air-gap steel wall shielding, which will extend 20" above the stove top. and be open to air flow. The space available in the corner is 36"x36" and I am trying to determine if I can fit the stove there safely.

It will be positioned like this:

I know the air-shield reduces the clearance requirements but by how much? Can I get safe clearance in this 36" square? I will have to maintain 18" stovepipe clearance to the wall.

Can these numbers be reduced x% based on the shielding type?

Thank you for the help.

Here are the required clearances to combustibles:

NFPA wall shielding can only drop clearances down to 12". According to the manual, further clearance reduction needs approval by the local inspecting authority.

The TH-100 has an exceptionally high insulation requirement for the hearth. What will be the tiled pedestal's insulation layers to achieve R=2.8?

If you haven't already purchased the stove, there may be better options for heating with lower hearth and clearance requirements. Heating a cold bunkhouse with a tiny .6 cu ft stove will be a challenge unless this is in a mild climate zone, especially if it is poorly insulated. It takes a lot of extra BTUs to warm up a cold cabin.

The stove only require 10" from the corners to combustibles, so with shielding?...
I was going to do tile over backer board for the top of the pedestal.

With shielding still 10" and tile over cement board is no where near enough r value

Oh man, R value of 2.8 seems crazy high....

Too late I already have the stove

It is indeed. Home Depot has a good return policy...

Clearances and hearth R value are missed by people shopping for their first stove.
I have rear heat shields on the stove and single wall pipe out of the stove.

Thank you all for helping me with this. Stove return process started. A PITA but I am glad this was caught.

Anyone have a tiny stove recommendations for this corner space. The bunk house already has electric heat this is mostly for aesthetics so it needs a window. ;-)

Has me wondering how these are installed? I wonder how many unsafe installations are out there...

It's a new stove with too short legs and no bottom shielding. Most likely an import from China. It may be ok for cement floors. I suppose a hearth could be made out of cement blocks with cement board on top.

I'm not too fond of HD's stove selection but of them the small Pleasant Hearth is ok. It has easy hearth requirements.

I will have to maintain 18" stovepipe clearance to the wall.

On some of the stoves with super low clearances and ember only, the pipe may end up being the limiting factor. There is a double wall stove pipe that lets you get a lot closer to combustibles if you find a stove that will let you get close.

My Aspen C3 is 3” corner to wall and that keeps the double wall clearance at 9”.
Single wall pipe needs 6” on the corners.

It’s also ember only, so I stole some 3/16”steel from a welder I know and painted it black.

I think it’s advertised at 400-1200sqf.

What is the Aspen C3 selling for these days?

 

[30WCF]

$1800. I might have missed if there was a budget we were shooting for.

OK thanks all, I have a lot of research to do.
