new installation pipe question

[pelletpot]

New here. Excited to get going with pellets. (tired of cutting wood) I grew up with wood stoves and have installed many different stoves in different houses etc. My question now is I want to replace a dead propane stove in an area we haven't needed to utilized til now....with pellet stove and use the hole already cut into the outside wall with all new pellet approved pipe of course. The installation will be out the back of pellet stove with an adapter, then a T with clean out, then vertical up to the hole through the wall, then horizontal outside to proper clearance for an end cap. When installing wood stove pipe you can just cut the single wall pipe to fit the length you need. How do you do that with double wall pellet pipe? You can only buy it in certain lengths so how do I match up the exact length needed to fit through the pellet thimble that I will install in the existing hole?

thanks for any help

They make an adjustable double wall pipe that will solve your height set up. I have the exact same set up with a vertical rise of about 4-5 feet which is ideal for draft. Technically, all the other connections have the built in gasket that doesn't require anything further, but the adjustable pipe requires a seal once you have the height correct.

Best of luck!!

I'm sure you already know that the approved pellet/corn pipe is not cheap. And they will get you double for that adjustable one. Just a thought, if you are just a few inches short of reaching the hole, could you build your hearth pad up to match? Or just add four nice looking landscaping type blocks under the stove legs. Easy enough to chip or grind the block to the right thickness.

Or just block and cover the old hole and put a new one in to match your vertical rise. Even that is probably cheaper if you don't count your time involved.

WOW, they've come way down from a few years ago. That makes it easier.

Lowes pipe
12" regular 15.98
12" adjustable 26.98

There is a very small range of adjustment that will not work.
I did an install a couple of weeks ago, and could not get a combination
that would work.. very slim chance you will get it,
but as luck would have it, I did...

I know w/ pelletvent pro they have a 18" and 12" adjustable length. I would not recommend using the Lowes pipe. It is the old style w/ rope gaskets and the crimp down the side of the pipe. The pelletvent pro is oring sealed and smooth sided. Much easier to install and does not require sealer. Lowes pipe will leak if joints are not filled w/ silicone prior to installing

You can buy about a mile of high temp silicone tape that works awesome, and allows you
to take your stove pipe apart, for the difference in price between the Duravent, and Pelletvent Pro pipe..
Not saying the stuff isn't good, just that it's very expensive...

Jus went through a new install myself. I offer jus a few things I observed. It is easier in my opinion to buy solid lengths as close to you can get to your length than it is joining lots of 12" jointed pieces. Lets say you need 5'2" to get ya centered up with your 90 degree elbow to go out the hole. Get a solid 4' length then an adjustable to complete your other 14" to elbow. I used the Rutland 500 degree flexible clear silicon... great stuff. Also... let the silicon cure for 12-24 hours before running heat through it. After it cures... those joints become like cement... they ain't never coming back apart. In my install... my tee/cleanout is also inside. It is the only place I get any smoke from when the stove does an initial ignite. I used silicon around the rivited joints and use some aluminum tape around the cleanout cap joint... smoke is very minimal and only during initial ignite cause smoke does not start drafting good till you have fire/heat through the pipe.

Also... IMHO Rural King is a great place to shop for Duravent 3" pipe. Good selection, great service and good pricing all at one stop.
