I bought a bunch of 4' Duravent Pro piping for my enviro maxx. Whats the secret to getting it together? I cannot get the pieces to twist and lock into place. I am using a hammer and piece of wood to make sure that the pieces are fully seated, but then it will not rotate even with a strap wrench. HELP!
 
Jeez my SELKIRK went together great!:rolleyes: It came with some sort of lube that went on the joints, maybe yours should have and didn't....
 
They seem kinda greased already, is there any specific lube I should use? You know, something that won't smell and potentially burn off/light on fire? How important is it that they twist-lock in place if I am sealing with RTV?

Lock them! Anitsieze may help.
 
Don't think I'd RTV the mating surfaces on the joints unless you never wanna get em apart again. If you end up using grease, wipe the outside of the seam area THOROUGHLY with alcohol or something to degrease the area. DON'T go nutz with the grease. Just a real thin coat (If there's now marks on the pipe where it's binding, just start by lubing those areas first). Put the degreaser on a rag and try not to get it in the joint or it'll keep flushing grease out. After it's clean and dry, smooth out a bead of RTV on the outside of the seam. When it's dry, give the joint a once around with tape.
 
I used pelletvent pro piping also and they are a snug fit. On the plus side I haven't ever had a leak with it on my stove or any of my buddy's I helped install.

Yes they are tough to get together. Use a bit of grease as P38x2 suggests. I ended up using two rubber strap wrenches and even then I had one I couldn't get all the way. I ran the stove through a couple cycles, heating it up and cooling off, viola it went together easily. My year end cleaning was a snap. All the pieces went together without any problems.

I also just finished a Selkirk DT install on my stove in the basement. The Selkirk goes together very easy, but the fit and finish is inferior to the Duravent IMHO. Only time will tell.
 
Well, the grease worked like a charm . . . . . EXCEPT for the stove adapter which slips over the outlet on the back of the stove. For some reason that piece will not twist even though it slides into the adjacent pipe near effortlessly with the grease on it.
 
i got 3" ss flexpipe going up a 20'+ chimney, no problems.......overkill
