sealing the stove pipe

PostBy: dtzackus On: Tue Sep 30, 2008 6:59 pm

Hello Everyone,

A big and exciting weekend. The Gibraltar LCC finally came home and installed!!! Now, I am awaiting the colder weather now!

A BIG THANKS to coal berner for showing me (and answering all my dumb questions) his knowledge of coal, and mind you he is a walking book of coal! Again, thanks!

I have the stove pipe all cut and know just awaiting to set it in place and seal it. I was just curious about what everyone else did with the seams on the stove pipe. Coal Berner stated to use the 3M Flue Tape, but I cannot find it anywhere and trust me I looked.

O well, can't wait to get the 1st and only fire going soon!

Hi Dan, when the stove pipe is installed, it will be under a slight vacuum.. most people just slip the joints together and install 3 or 4 screws per joint.. If you want to seal the slip joint, you can use silicone sealant from an auto parts store, or you can find high temp tape and tape the joints..

Don't forget that the horizontal section and elbows will collect fly ash through the burning season, so you will need to take the pipe apart a few times a season to check for ash accumulation and clean it out..

I think most of us just put 3 sheet metal screws in per joint (not the smoking kind ;) ) & call it a day. I dismantle my stove pipe every spring (Ito clean it out) & leave it dismantled through the summer to avoid corrosion/moisture. In the fall I put it back together & replace any questionable pieces. Any joint sealant would just make this process harder to do.(the joint will b plenty tight with just the screws &, once your stove is running, the draft will suck room air into the pipes anyway.......no CO or smoke/smell should escape into the living area.

Dan I sent you a Pm on where to get the Tape and Like I said you won't find anywhere around here Here is the link incase
you did not get it http://shop.doityourself.com/invt/u195412

I think I have a some left on my roll yet I will bring it over to your Place You can also get at bomberger Down in Lititz
if you are up for a ride I will say this I would use it after having my 3 Co Detectors go off over 6 times last winter at 1am
3am I would use the Tape it can and does come out of the pipe joints with the right condition after I tape them up
no more Detectors going off Your Like me you have little ones Running around the house better safe then sorry I will

come over with the tape You do not have that much pipe so taking it down and cleaning it will not be a problem you can take two pieces off and keep the rest on the other pipes I used it over already once I clean the pipe out the tape will stick again you only have to take the tee off to clean yours or just take the baro out and go threw there when its time to
shut it down for the spring just take the 2 ft piece off the chimney flue and cap it with your cap No big deal see you this weekend Oh one thing I burned coal for over half of my life and never used tape on the joints until last year when the
Co Detectors start going off So to you Guys that don't think it can come out of the pipe joints it can and does and yes I
use sheet metal screws on the Pipe joints 3 to 4 on each joints So Just because it did not happen to yet don't think it can't

Jay, you must have had a draft reversal, or a restriction in your chimney,, the only way anything can leak out of the joints is if there is no draft, but a slight positive pressure.. maybe the wind was blowing just right and the stove wasn't making much heat to create very much draft??

Greg As you know My stove puts out a lot of heat So much that that box full of cheap Thermomenter I bought you know
like the ones I gave you are all melton The heat was not the problem And as you know there was nothing in the chimney nor the stove pipe I can burn 5 tons of coal and only have 1 to 1 1/2" of flyash in the stack pipe You called me the day I was checking the pipe and chimney out The only guess that I had was the wind backdrafting down the chimney all I know I burned coal in that chimney for the last 13 years and never had a problem
Once I tape the pipe joints The problem stopped what was weird was it would go for days or even weeks with no Co
Problem then it would just start up always in the early morning hours So like I said with the right condtions it can and does happen

Yeah, that sounds like just the right wind/weather conditions...

Or... you had been spending too much time with your Gibraltar, and it got lonely and missed you at 3-4 AM, and the only way to get some attention was to set off the CO alarm :lol: :shock: 8-)

My guess is, you had an "obstruction". Not a physical obstruction, but a "cold air obstruction". I think, that under certain conditions of low heat, low draft, stagnant cold air at the top of the chimney can prevent warm air from breaking the barrier and actually allowing draft. This would seem to be more of a potential for "outside wall" chimneys. I think, this has been discussed before.

Fireplace construction, includes a "smoke shelf" to prevent back-drafting. This would indicate that it's possible to have both, air travel up the chimney, as well as, air travel down the chimney, at the same time.

Yes Dallas I should of mention it was a outside chimney AA S.S. Thanks for posting that

The potential situation was on my mind from yesterday.
I was starting the stove and couldn't get the draft, I expected. I shoved the output of the vacuum cleaner in the stove pipe, above the baro and everything, thus creating an updraft in the chimney and a venturi effect on the pipe to the stove (essentially a "draft inducer"). The fire quickly took off. Hmmm ... :?:
