Vertical Venting Inside or Out?

[JennaT717]

Hello everyone! My husband and I are brand new to pellet stoves and just ordered a 55-TRP10T - EPA Certified Pellet Stove from AM FM Energy (Thanks to this great forum site)! We are installing the stove in our main living area through a combustible wall. Originally, the husband wanted to just run a pipe horizontally through the wall to the outside and put a thimble (i think) on it but then I read posts about back draft so now we are wondering if we should install the venting vertically on the inside of the house first and then horizontally to the outside or horizontally inside and then vertically go up the house on the outside? If it does not matter then is one way easier to clean than the other? I have seen people posts about 3' or 5' vertical venting and I am wondering what your thoughts are on that too? Thanks in advance for all the great advice! https://www.hearth.com/talk/threads...pellet-stove-1-500-sq-ft.148858/#post-2000089

If you do the vertical on the outside that's where you'd put the cleanout t. Keeping the chance of a messy cleanup outside. Either way it shouldn't be messy though. It's up to your preference really.

Thanks so much!

Also 3ft is plenty just make sure you have the proper clearance from windows,doors, and combustables.

If you go up then out, it's easier to get a nice neat install if you ever replace the stove with a different model. If you go straight out, it's a challenge to match things up.

You might also think about going up a few feet, then out, then up some more. That's what I did, because I replaced an old wood stove that went into a masonry chimney. Actually, I hired a certified installer who did a great job and thought of stuff I never would have. It was money well spent.

personally I like the venting outside out of sight and cleanout on the outside but bcarton does bring up a good point about ever replacing the stove.It's really personal preference.

Hi Jenna, and welcome to this forum !

As Shane1 noted, I went through the wall with a horizontal piece of venting then went vertical outside, where I put a clean-out T, to keep the vent cleaning mess outside. It also meant I only needed to seal the short section of venting that is inside with silicone tape to prevent smoke leaks, which can be more of a problem if the venting is inside the house. For some it is more a matter of visual aesthetics whether you have exposed pipe on the inside wall or outside of the house.

One consideration for going 5' of vertical venting rather than just 3' is that the 5' vertical venting will better allow for a natural convective draft to remove the smoke from your stove in the event of a power failure, with less potential for filling your house up with smoke. This is especially the case if your vent termination on the outside wall of your house faces into the prevailing wind direction, which can cause back drafts into the house when the wind speed overpowers the combustion fans ability to push out the smoke.

Another alternative that doesn't require a vertical vent section is to install a UPS - uninterrupted power supply system - that runs your stove on an internal battery power source for long enough that the stove can fully shut down and clear the smoke if the power goes out. APC makes a variety of excellent UPS back-up systems - type in "APC UPS" in the search query link at the top right of the page and you'll find many threads on this to help you with more info.

Regards, and good luck. DK

Horizontal then vertical. Why add an extra 90 degree to the pipe? 3 to 5 feet of vertical is fine. I prefer the full hood to cap the top.

I did mine on the inside and the wife and I both agree it looks really nice having the pipe on the inside it really helps to accent our hearth. This photo is pre mantel. We used a hand huned piece of 4by 8 for our mantel.

Inside rise is a good match to a traditional looking stove. Horizontal out and up is nicer for European-style stoves imho.

Welcome. I personally love the look of the vent pipe so I went with vertical inside and then through my existing chimney. I had to go 7foot up to make the clearances required.
