Need advice for woodstove in alcove

[NeedTheHeat]

How is the alcove install working out? I'm looking to do something similar with an MF Fire Nova 2 freestanding stove. (The Nova 2 insert would require a custom front plate due to the size of the fireplace opening.) (I've also read all about the smoke rollout issue users have had with it.)

I have an all-masonry 1940's brick and stone fireplace (no mantel). Two years ago, I had the chimney rebuilt from the roof flashing up (approx 7'), a 16" steel liner installed with insulation, and the firebox rebuilt. Two years later, I realize an open-fire that vents through a 16" hole in winter is not ideal, nor is the post fire smell that permeates the house.

This is more for aesthetics and occasional use than a primary heat source, but the opportunity to capture heat instead of venting the entire house is very welcome. As is the EPA rating for general indoor and outdoor air quality.

I'm planning a DIY install with city inspection (I'll need a 6" x 20' steel liner, appliance connector, 20"x20" steel chase, chimney cap and 1/2" cement board to block heat from going up 16" liner).

What the the clearance to the mantel of it combustible that seems like the only concern

For mine (NeedTheHeat), there is no mantel.

Moved to separate thread to reduce confusion.

It looks like there is a corner in common with a (studded?) wall. It could be ok, but the Nova 2 has a fairly large size clearance requirement of 20" and no alcove definitions. It's good to double check in advance. Can you post a picture or two of the alcove for guidance?

Was the Osburn Inspire 2000 also considered?

The Osborn is a good looking stove but too tall for the space. The left side of fireplace is open. So the wall is set back 24” from front of brick face. Edit: thanks for starting a new thread.

I love the open fireplace but it is not great for air quality and efficiency. The idea for a stove is to still leave some open space and solve previous issues. I’m open to blocking off left side with appropriate materials if needed.

Nice looking fireplace. The Inspire 2000 is 23" tall. It doesn't have to have a pedestal. Without it, it's a few inches shorter than the Nova 2 with a larger fireview and more user control.

The main thing to consider for either stove is the hearth extension insulation and depth. A low stove on a flush hearth is going to radiate a lot of heat out in front of the door. The heat radiated at floor level needs serious consideration. The Nova 2 requires an R=1.35 hearth, 16" in front of the door. That should work if the hearth extension qualifies. Is the hearth solid non-combustible with no wood or combustibles underneath?

I'm not finding the hearth insulation requirements for the Osburn Inspire 2000 with the minimalist base. This appears to be an oversight in the manual. I would contact SBI support if interested.

There is also the Stuv Cube stove with this minimalist configuration though the hearth requirements go up a lot for a low hearth.

Ah. Yeah. I see that now. I was looking at dimensions with the base.

Edit: it is a slab foundation so I’m pretty sure it is brick to concrete. I’ll need to review the house remodel plans to see if it is included. House was built in 40s.

Great info. Thanks!

That will probably be ok, though it would be worth considering elevating the stove on a 4" high base for more protection of the wood flooring. This could be as simple as 4" high cement half-blocks (painted black) or a metal shop could weld up a custom base.
