garage wood stove questions

[terwin1]

I've got a garage with an existing chimney in it. I would line whats there with double wall or something. the building is all brick except the roof. what do I need for wall clearance since the walls aren't flammable. I found an old earth stove for cheap I want to put out there. only to run on the days ill be out there all day. otherwise ill likely just use the salamander. pic coming soon. not so sure about the block chimney.

Clearance to combustibles is specified for stoves. If you have no combustibles then you don't need to provide any clearance. Consider floor space issues as well as service issues.

Start calling this detached building a shop or workshop. Solid fuel burners are illegal in "garages".

My shop has three overhead doors and a woodstove. It's great to have a wood burner in the shop.

I have the dreaded box wood stove in my shop, I only use it on weekends or when I am actually working on something.... Lol I KNOW, I know, evil stove... I used a double insulated wall pipe through my roof, I also went nuts and gave 8 inches of clearance around the pipe. But the flashing piece gave me a14 inch square, so, more, better I figured.

does this seem a little iffy to anyone else.

Is that supporting class A HT chimney?

 

[terwin1]

I'm not sure what exactly that means. its a flat rubber roof. chimney looks to be poured. The original owner of the home was a stone mason. I haven't checked to see if theres a pipe or anything in the concrete.

 

[terwin1]

looks like about 4" of masonry and a 1" air gap all around tho. that's code isn't it?

 

[begreen]

Ah, it's a masonry chimney then. It should be 2" from any combustible. Not sure if that is happening there.

That's crazy, my house was originally owned by a mason as well. The garage is constructed very similar...... cinder block with a flat rubber roof and a block chimney. My whole house and garage is also veneered in river rock.

 

[terwin1]

Yeah. I'll have to check if it's got a 2inch gap. If it does what do I need for pipe/liner in the masonry. Or just run like double up to the hole. Looks like the earth stove I bought has an 8" outlet. Not sure what that hole size is but I'm pretty sure it's 8" so a liner prolly won't fit through it.

 

[terwin1]

Think I did ok on it.

so i got this thing home. theres some weird like 1" black steel pipe inside of the flue collar stick up about 2 feet out of the stove with a union screwed on it. the other end goes down into the stove and 90's out the back of the stove. almost like it was meant to pull room air into the exhaust. Anybody have any clue whats going on with that.

oil drip?

 

[terwin1]

that's what I thought at first glance but it doesn't make sense. ill post a 3d model in a sec. I shoulda took a pic.

 

[terwin1]

pipe doesn't actually stick out the back of the stove. theres a threaded bung there that the pipe is screwed into inside the stove.

I'm thinking he ran water through the pipe to heat the water. Many have tried.

 

[terwin1]

theres gotta be a better way to do that. I could see it though. where the pipe goes up inside the stove pipe theres a union on that end like it woulda been threaded to another length of pipe going up the chimney even higher. otherwise he would have had to 90 it out of the stove pipe back down somewhere. It just doesn't make any sense. I'll just take it out and plug the hole unless somebody knows what its for.

I'd say taking it out and plugging the hole, as you said, is the best thing to do with it.
