Fellow forum users: I want to install a pellet stove in the basement of this cottage and need advice.

In the first photo, you can see the stove location. I want to exhaust the stove out the stud wall (wall with the window) between the first and second studs in the corner (you can see where the studs are as the drywall is not yet painted). The side wall is ICF.

The second photo shows the outside wall where the stove will exhaust. The pipe will come out about 3 feet below and to the right of the light fixture, close to the white trim on the siding, then make a turn and extend out about 1 foot beyond the deck above. This will place the end of the exhaust about 5 feet from the operating window you can see in the photo, and about 20 feet from the intake for the air exchanger down the side wall – if you look closely, you can see the intake.

I’ve read the Code, and this appears to be an acceptable install – but I thought I’d check with the experts first!

Any tips or suggestions are greatly appreciated.

Are you saying you can't go out that green vinyl sided portion of the side wall because it would have to be through ICF?

Can you provide the vent path starting at the stove adapter (I'm having trouble calculating the EVL) ?
 
Correct - the side wall is ICF, while the end wall with the window below the deck is a stud wall - otherwise, I would have just exhausted the stove out the side wall instead of coming out under the deck.

My plan is this: T at the back of the stove (with clean-out), up 3' to a 90 degree elbow - out through a thimble in the wall. Once outside, I'll go at least 12" out from the siding, then make a 45 degree turn and continue out about 12" beyond the edge of the deck. I'll put another 45 degree elbow on the end of the pipe with a screen.

All pipe is 4".

In total, I figure the exhaust will run about 8'-9'.
 
Although I don't have the pellet stove knowledge that the guys/gals on here have, I would not want my stove venting under my deck!

Definitely off topic...But how is the beam connected to the column on your deck framing??

You'll be fine with the 4" and that configuration. I'd stay closer to the siding than you would as most double wall pellet vent allows usually a 3" clearance to combustibles and a lot allow 1".

It is rare for siding to be over foundation concrete and hence my question about the ICF.
 
Thank you, Mr. The Bear! I'll take your advice.

Eatonpcat: The beam and post are nailed together and there is a 2x6 cleat on the opposite side which you cannot see. Also, I have yet to install the triangular braces. This is all that is required in my area.

That's not enough support for me... Now I know why that goof Mike Holmes always says minimum code is just not enough!!

Good luck with your stove install...Looks like you have a beautiful home!!!

Not an expert but I notice the smell of burning pellets radiates some distance outside my house. I have a similar grade with stove vent on side of the house and sometimes get smoke smell even in front of the house depending on weather conditions. I suspect you may get an occasional whiff through the heat exchanger but hardly anything harmful unless someone is really sensitive.
 
This may sound like overkill, but I'd run it out under your deck and as closet to the corner as possible, then put a 45 degree pipe right where it comes out and then a straight run all the way up along your corner trim piece up through your roof overhang with about 4' of additional pipe before the cap. Costly, but it'll vent better and you won't have smoke wafting around your windows on those days when the air is stagnant and heavy down in that "hollow." And given that you appear to have a complete new build, what's an additional few hundred bucks in venting for the best draft you can get? Just my opinion.
