Jotul 507 Clearances

AKShadow · Post by **AKShadow** » Sun. Aug. 26, 2012 9:38 pm

Hi Jotul users,

I am about to install a Jotul 507 to supplement heat in my house which is primarily heated with a Blaze King wood stove. Everything was looking
good until I looked at the spec'ed clearances in the Jotul manual - 30"! I've read they run hot but that's a TON of space. Is everyone running these
stoves also running the 30" clearance? Anyone know anything from international building code that can give you a legitimate cut on clearance?

Thanks,
Erik

Generally you can figure on cutting that distance in half if you protect the wall with a heat shield of metal, or cement board, or masonry, etc, spaced 1 inch from the wall and floor. A heat shield placed anywhere between the stove and wall will work also but would be frowned upon by an inspector because it probably would not be fastened down. Even at 30 inches a wall can get pretty warm with a stove running 24 hours a day.

the info Ive found around the interweb confirms your statement about 50% and a 1 inch space with non-combustible shield. Right on, thank you.

Yup... not only the Jotul, but ANY wood or coal stove requires 30 (but I always thought it was 36) inches unless it has a shield. Don't forget to have the shield one inch off the floor as well as one inch away from the wall. The idea is to make air flow. One shield only! That is, you can not do 2 shields and go to 9 inches or three shields & go to 4 1/2.

AK, I just pm'd you an owners manual for that stove. They are hard to come by. When fired hot, that stoves temp can reach 932f. That's pretty darn hot. Don't cheat on the clearances or bad things happen. You should double check your wood stove clearances since you were surprised by the Jotul clearances. This is a problem that gets worse with time as the ignition temp of adjacent wood gets lower and lower. I've seen several devastating fires from this.

Glad you mentioned that. I learned that a few years ago. Normally wood is said to have an ignition point of about 525 degrees F. But, after long exposer to warm air, hot air, it has been recorded to ignite as low as 302 degrees!!!!

Thanks for all of the input guys - and the manual too! My Blaze King has a manufacturer specified clearance of 9", so that's how I installed it stove last winter. I also have a copper heat shield spaced 1" out from the wall.

Really having issues with this 30" clearance for the Jotul. I know cheating isn't a good idea, but is a 50% reduction with a heat shield really cheating? Anybody have a quote or copy from the NFPA on this issue?

I don't consider it cheating. It is now a noncombustible wall.

If you put stove clearances in the search box in the upper right you will get many threads.

Google "NFPA coal stove installation clearences" click "FNR100"

A properly installed heat shield isn't cheating.
