Help with older stove choice

[Dfdsc68]

Hi all, so I currently have a newer ambiance outlander 19 stove. Produces about half 75k btu. Corner install double wall inside to triple through the wall. I do not feel I’m getting the heat out of the stove I should.
No damper in pipe due to it being a double wall. Only an air control on stove.

I have an opportunity to get my hands on an older fisher or single door rebel stove

What is the clearances needed for a corner install with this old steel stoves. I always seem 36” from the rear to the wall
I currently have wonderboard direct to the plaster wall with cultured stone adhered to it. No air gap.
Can I affix a heat sheild to these older stoves. (I am a welder by trade) utilizing 1” spacers and some 3/16 plate off the back to gain better clearance?


Help is needed. Thank you

No, a proper, ventilated, NFPA 211 wall shielding is required to reduce the 36" clearance requirement down to 12".

Before giving up on the Ambience, perhaps consider why it is not producing great heat. Most frequently this is because the wood is not fully seasoned, but there are other possibilities including an incorrect flue setup, or operator error. This stove is a secondary combustion stove so that once burning well, it will actually get hotter as the air is turned down.

I figured as much.

And yes I have noticed great heat with well seasoned wood, I have double wall inside is it possible to put a damper in or is it needed?

Yes, that can be done if necessary but usually this is only if the chimney is quite tall. How tall is the flue system?
