Clearances to NON-Combustibles - Harman P68

[dainger]

I just picked up a 2006 Harman P68 as a secondary heat source for my home. I plan on doing a corner install. I can see the minimum clearances to combustibles, but what are the clearances required for non-combustibles? I plan to replace the drywall with cement board and tile on top of it... I fear the stove may be too large if I can't get the clearances down.

For a corner install it is listed as 13" without shields at 9" with shields for combustibles. Curious to know what this would reduce to for non-combustibles...

AFIK, You can put it right against the non-combustible wall. If you are adding harder backer & tile to wood studs. You’ll hafta leave a 1” air gap between the studs & the back. As well as 1” off the floor & ceiling allow for air flow.

Even if you build a non-combustible wall, you need to adhere to the clearances for the combustibles behind the wall (studs, etc)

I would caution that you probably want it away from the walls anyway for maintenance back there - and the manual states that.

As I read that 3" is from the back corner of the hopper to the wall. I think that 13" is for alcove walls alongside it. They don't want anything between the walls and the stove for those 13". I could be wrong.

Here is a picture from the 2014 manual - which is more clear to me and says that the 13" is from the back corner of the stove (not the hopper).

And just for good measure, here are the hearth requirements

I agree with Bogieb. You need clearance behind the stove for maintenance. If not, you'll be pulling the stove out every time you do cleaning or maintenance. That'll get old real quick!

Especially with the weight of a P68 being around 300lbs empty

instead of listening to different opinions here. Call your local inspector that you are going to have to call anyway to meet your insurance requirement's and ask for their advice. That's what i did and my inspector was great he answered several questions i had and when he came to inspect he was more than happy with my install. Just remember if you go to close to a wall even if you have it fire rated if you need to work on the stove you may have to disconnect and pull out every time you have a issue. Myself i wish i would have thought of this instead of going to the min clearance on the back as it makes it hard to get the side panels off i had to modify a screwdriver to get the screws out and they are a reail PIA to get back in when i cannot see the holes.
