frustrated with dura vent

[mikhen]

Just replaced my vent, after the tee and 90 were leaking. Couldn't get pipes apart so I replaced the whole thing with duravent with the rope gaskets. All 3 of the places I talked to said that sealant is not needed.
After installing, smoke was coming from the seams in the 90 and tee, and also from between the 2 layers of pipe at the clean out cap. So I contacted duravent, and they told me I need to seal the joints. So I did. And guess what.....still smokes from the seams in the tee and 90 and the clean out cap. Only for a few seconds at startup. Is this safe/ normal?

If you have a leak, your CO detector should go off if the levels get to high. When I started my burner up, I swear I had a leak but my smoke alarm and CO detector reads zero so I have not touched it. I think the "seasoned" burners will give you there opinion on how/what to do

Gardner bender has a high temp self bonding silicone tape. Can be found in electrical dept. very stretchy. Other brands as well. Couple stretched wraps per seam and your good . I picked up a roll of ten feet by 1inch for $5. Most box stores have a version for around $7

personally If i saw any smoke i would fix it or have a professional come and repair the vent I would not rely on a co detector if there is smoke present. even a little bit of smoke should not be left alone!

If you're SURE you sealed EVERY seam, joint, rivet, etc..then you either had some crud on the pipe causing the silicone to not adhere in spots OR it's not leaking where you think it is. Check your adapter. I'm assuming it's taped. Foil tape is notorious for getting little ripples in it which can act as little conduits for smoke to escape. Also, make sure your thimble is sealed properly. If you're smelling it at startup, mid burn or shutdown, it's not normal and is still leaking.

ETA- I agree, it is frustrating. Had to seal everything on my basement stove. I think on an articulating piece such as an elbow, leaks are fairly common.

I had this happen with Selkirk. Sent it back, and they welded the seams on the 90 and the tee, in spots that are not normally welded. Although my problem was worse, I had embers coming out of the seems. Like others said, make sure you put sealant the whole way around, and then restart and check for leaks.

If your close to a dealer that selling ventis pellet pipe by Olympia put that in haven't sealed any yet that stuff is awesome!

I used duravent pro which has seals built in instead of rope. I've had good luck so far

Turn off the lights and use a flashlight to look for leaks then get some of the high temp silicone self adhering tape and start taping. Also when I had my first pellet stove I put a screen on the pipe to keep critters out but it was to fine a screen. Long story--short the screen clogged up and forced smoke all over the place.... inclulding the joints of my venting.

IMO, all exhaust piping sucks. especially mine. it looks like a broken arm with a cast on it wrapped in an ace bandange glued with a sling.
but it doesn't leak anymore

Yea it kinda does. If you paint it hi-temp black that helps..... some.

I have an insert, so I don't care how ugly it is... its all hidden.
