wood stove install?
I have and old vented propane heater in my gargage Its way to expensive to run so i bought a woodstove. The stove has an 8 inch pipe. the garage is block with siding on the outside. what do i need to do to get that pipe threw the wall without melting my siding or catching the garage on fire. Ive been looking online for information it im not having any luck. Also the cheaper the better.

You could vent it through the roof -
Double-wall, stainless-steel -
keep it away from flameables (wood).

Can you go through the roof instead?
It's not going to be cheap by any means to run it right.
If you go out the wall your going to need a wall stand to suppport the vertical piping, lined pipe so it's cool enough to not melt the siding, standoffs to support the pipe, it has to be run above the roof line and also need a cap.

i could go through the roof would that be cheaper? My roof is about 14 ft off the ground where i want to put the stove any wild guesses on how much it would cost to go through the roof?

No idea on exact cost. Look though the site I posted to get an idea on what needs to be done to keep it safe. No need to buy that exact brand, just wanted you to know that parts are needed
Still would need a thimple where it goes through the ceiling that holds the pipe and keeps it from moving and a roof jack rain shield and cap.

ok i was thinking of using single wall pipe because its cheaper i have a drywall celing what would i need to do around this to stay safe but not have a big hole arond the stove pipe for clearance. Sorry for the dumb questions i have no experience with wood stoves.

What kind of siding? Common sense says that the block wall is the safest approach. I'd likely go to double wall to keep the portion of pipe inside safe to those around it though.......

kevin07 01-28-2013 08:52 PM

vynl siding. Would double wall be cool enough to have the siding tuching it? or would i need a thimble? Also would 2 90s and all single wall cause a draft issue?

Single wall would burn out within a year or so.
No double wall can not come in contact with the siding.
No it can not even come in contact with the drywall. It was to be at least 2" form any combustable material.

I am usually an advocate of doing things yourself but, in some instances it is time to call in someone who knows what they are doing. You (the OP) indicated that you have no experience with wood stoves. My brother recently had one installed in his home. Single story thru the roof. I was impressed with the care and knowledge that the installer had when opening up the roof and installing the proper roof safe and piping. Properly sized pipe is important based on the stove to ensure proper heat retention in the pipe so it does not get too cool or too hot. Both of these situations can cause problems for the stove, chimney, structure. I would advise to at least seek out some expert opinions on a proper instalation.

Would still need a thimble. The pipe would need to be a flue pipe rated for solid fuel. And it would still have a min clearance needed from the siding. Single wall clearances are much greater then All fuel requirements.

EG: On gas, B vent requires 1" all the way around it, single wall pipe requires 6" all the way around it.

Going out the wall will cost more than roof----

Danpik made a good point---flue sizing is key to proper drafting of the smoke----

Most stoves use 6" --so do find out what is the correct pipe size for your project---

I would also check with your home insurance carrier. Wood stoves often cause an increase in premium costs. Also check with your local fire inspector for any special requirements for a stove in a garage.

You might be better off building a simple cinderblock chimney. Might be cheaper too.

Is the stove you bought new, or used? I don't remember the last time I saw a new stove with an 8-inch flue.

kevin07 01-29-2013 02:30 PM

It is a used stove its a Schrader it has an 8" single wall pipe attached to it. I will be doing the install not paying anyone to do it. I just need to do my research and find the proper way to install it and i will follow the all the requirement to make it safe. I think im just going to find a local store that sells woodstoves and pipe and talk to them to see what my options are.
