    The issue you will have is you will not have any natural draft/draw. This will come into play when or if you power goes out and your combustion blower stops, you can have smoke coming back into the house. I would suggest at least have a little bit of a vertical once outside if you are worried about looks inside. Also check in your manual as it may require some vertical in the venting.

    Straight out, no rise. Works well.

    The guy at the stove shop said that it would be a 7" pipe, with the fresh air built in, and that the pipe was designed to take care of the smoke in case of power loss. He also said that the stoves are so air tight that he didnt think that smoke would ever be an issue in a power loss.

    Look at the stove Manual, it will list those requirements.

    OLD Trailblazer stove.
    Using a 24" vent pipe straight through the wall. I bought a 36", but was concerned about smacking it with my head while mowing the yard.

    The 24" straight seems to be working fine. No soot or draft issues to report.

    I do plan to turn up and go above the eave line when finances permit...mostly for aesthetics.

    7" in diameter? Fresh air "built in"? Never heard of this. Interested in
    what Rod or some of the other installers on here will have to say about it.

    Read around this forum and then tell us if you still believe him.

    Hi Johnny,

    I also replied to your other thread. The dealer is wrong about the smoke not backing up. Even when brand new I had smoke billowing right out through the front of the stove the first time I lost power. Set of the smoke detectors and everything (at 2 AM!). I added outside air last year which really improved outdoor air quality, and absolutely eliminated creosote build up on the glass (it was a significant problem in year 1). However adding outside air did nothing to prevent smoke back-up on power failure. I added a UPS for that an am optomistic that this will cover me...but a rise on the pipe would be even better.

    I think i've heard about the pellet pipe with built in outside air. Simlar in style to the vent kit i've got for my Rinnai Propane heaters. Makes sense, but i'm not sure how it would work with the st croix. The damper that draws in air is off to the side...so I wonder if he knew what he was talking about? Could be, but I don't "get it"...and he is definitely wrong about it being completely air tight

    selkirk metalbestos makes a direct vent pellet setup that uses the same principal as a direct vent gas pipe , the intake air comes in through the outer shell to a shunt that connects to the stove intake, the smoke is carried out through an inner pipe outside. its simple, one hole in the wall , and i wish i had come up with it , great idea!! the other makers probably will field somthing like it if selkirk didnt patent it.

    as for the direct vent no vert setup , it will work ok as long as power is present , however if power is lost in a lot of cases it leaves smoke in the house. i never ever recommend that setup , and i believe it is not legal by code in canada, probably will be soon in the us , hopefully anyway

    When I used to install I would, at customers request, install as you have described. I never recommended it and even wrote into my estimates that it may cause sooting on the side of the home and that remedying this situation would be at the buyers expense.

    Yeah, I can see how advertising like that could sort of put you on the spot. Liability, liability, liability. :shut:

    Thanks for your comments. I have decided to go with a rise. Now, do I want the rise inside, or outside ? Pros/ Cons ?

    I'd planned on putting the rise inside where I thought it would look better until I realized that would put my cleanout T on the inside of the house. Ended up putting it outside simply to keep down the mess when cleaning the flue.

    Not really
    just that with the pipe in the room you see the pipe and the stove will be out in room more with the pipe inside and up.

    Out a wall and up make a cleaner look inside
