The topic of what are acceptable clearances for stoves and stove pipes to the nearest combustibles, comes up a lot.
The NFPA (National Fire Protection Association) section 211, that covers "solid fuel appliances" are tough to find without buying a subscription, or by signing up at their website where supposedly, the standards are free. Here's a link to that free section 211. http://www.nfpa.org/codes-and-standards ... e&code=211
In the meantime, below are two tables from the NFPA that show accepted clearances and the accepted methods for reducing those clearances. The first one is stove clearances. The second one is mistakenly listed as stove clearances also, but it's actually "connecter" clearances - meaning the pipe connecting the stove to the chimney.
It's my understanding that most municipalities and insurance companies use these national codes as their standards - either in whole, or part. I post them only as a guide. You have the ultimate responsibility for making sure your stove is installed safely. If you have any doubts, it's best to check with your local code enforcement, or your insurance company because they have the last word locally. BTW, Insurance "agents" rarely know the correct answers to fire codes so it's best to contact your insurance company directly. In other words, don't tell them it's ok because Paul said so.
Remember, the time to make things safe is before problems can happen. If you have the slightest doubt about what your doing, do the safe thing and seek professional advise.
