woodstove installation questions

Hi there.

We have a King brand woodstove. Its like a furnace, I could add a picture if necessary. Its rectangular and throws off heat like nobody's business. We installed it probably three years ago but decided that it really needed to be moved to the other side of our house and my dh decided it needed to go through the wall instead of up through the roof.

so. anyone have a through the wall installation? The stove shows a diagram on the back where you can vent straight out through the wall and then up the side of the house, so we went and got the support kit for that. We are going to install a single wall pipe ( 18" ) to the thimble and then the chimney is triple wall pipe. oh and the pipe from the thimble to the chimney is triple also.

I am concerned a little about the draft, I certainly do not want any CO laying in the length of pipe from the stove to the chimney ( 18 inches plus 12 inches). Maybe I am worrying about nothing as long as our chimney is high enough to keep the draft going.

I guess I am wishing I had the orignial installation paperwork, but we got this stove secondhand. It is a great stove and we have never had an issue with it, and I really don't want to get another one ( but totally would if I had to).

any thoughts?

Through the roof is typically a better installation, but more fuss to it.

So through the wall, tho a poorer option, is typically what people do.

As rambler said, many stoves are connected thru the wall. The rule of thumb - if not code - is that no more than two 90º elbows be used in the entire stove pipe/chimney pipe set up. If you comply with that standard, you should be okay.

Thank you I appreciate the input.

You don't say where you are. If you run the chimny pipe through the wall and up, a lot of it is outside in the cold and will be cooler than if you ran it up on the inside and through the roof. A cooler chiminy will form more creasote and not have as strong a draft. The colder your climate the more you get this effect.

If you can put in 2 45 degree elbows with a few feet of pipe between them rather than a single 90 degree elbow you will get a better draft.

Be sure to mind the setback distances between the chiminy pipe and any flamable materials.

we are in northern NY. We are installing a chase outside to help with the heat loss ( as recommended). The entire length of chimney outside is 11 feet ( one story house with low pitch roof) and yes we have the minimum 18" between the stove and combustible materials. And we will be installing a heat shield on the wall where the thimble is. Because of the way our house was built if we went through the ceiling it would place the wood stove in the middle of a wall in the room rather than in the corner where we need it to be, that's why we are doing a through the wall installation.

I live in NY and did a thru the wall on a two story house, Followed all codes and was obsessive about safety clearances. My set up is great and I am happy with it HOEWEVER I will need to clean my chimney every 6 weeks as the creosote build up mentioned above is a real problem with an out the walll chimney. Do not ask me how I know this!~ Vickie
