We did some remodeling on the room our pellet stove is in and built a new hearth pad. We also turned the stove to face a differ direction. Now the existing vent pipe doesn't line up with the exhaust on the stove. Stove was angled and now is parallel with the wall the vent is on. The high difference isn't a big deal, just not sure how to get bend/turn to meet the pipe since it doesn't line up.

Yeah...I could move the stove to make it line up, but then it wouldn't be centered on the pad and the wife would be unhappy!.

You could do a 90 off the stove, and a 45 coming into the existing pipe. To minimize elbows. You would only be a single 45 more elbow than you already had.

Sound easy enough. Dumb question...can the vertical pipe get cut to length or do I need to get a specific length pipe? I can't remember if it's tapered to fit the joints.

I’m not familiar with all pipe types. But you likely need a specific length or an adjustable section. They need to overlap and be sealed.

If you had your cleanout tee coming off the old stove then you can still keep that.

While cutting and crimping is possible, it'll void any UL certification if you cut (alter) a listed part.

All the popular brands (Selkirk, Simpson, interlock (twist lock), they have to to meet the UL certification and remain sealed. Keep in mind that they DO NOT interchange with each other so you need to stick with what you already have, or replace everything with new.

Far as height from the unit to the wall thimble, it needs to be slightly up hill or level but never down hill.

I get all my venting from Ventingpipe.com Have a huge selection and deliver fast and much cheaper than a local retailer.
