I just put in some chimney pipe for a wood stove. The slip joints have a
little space in them. What is good for sealing up these joints?

My first thought was JB Weld. Is that good, or is there something that
would stick to the metal at those temperatures?

You're using the proper double walled modular chimney pipe for wood
stoves I hope? The single wall stuff is for gas fireplace inserts and
the like and is not safe for use with a wood stove. If you're using the
correct items, you do not need any additional sealant. Also remember
that the metal will be expanding and contracting and JB Weld would
likely be a disaster.

You shouldn't need to seal them if it is installed right. The right way is
the joint is lapped so the creosote doesn't run out and down your pipe.
Round here tis a sure sign of a greenhorn. Also put three sheetmetal screws
in each joint.

Creosote should never run out of your pipes! If it is you
are firing _way_
too low! The inside of your stove should be white if you are
firing up
like you should be! A hot house has a clean chimney......;)

There are gaskets specifically made for this purpose - the place you
bought the stove would have them....
Get copy of the relevant installation standards as well, might be
illuminating for you....

I would not use JB Weld. It will not last long. I think the best
stuff is furnace cement. It will crack, but you really don't need a
perfect seal.

The single wall stove pipe is safe to use, but not where the pipe goes
thru the wall or roof.

Too ease everyone's fears, the single wall pipe goes into the ceiling box,
then a triple wall takes it through the short attic space. All a vertical
run. I just had a couple of small places I was concerned about.

Draft, then the soot from the smoke, will seal single wall chimney pipe.

Stove pipe cement maybe?

I have one slip joint where the black iron pipe goes (a long way) into
the stainless steel adapter for the double-wall chimney. I sealed it
by wrapping all my spare flat door gasketing around the joint.

3 screws is the standard but I like to use 4 or 6 stainless steel
flanged hex head screws which are easier to drive straight than
Phillips, so the holes aren't damaged when I reassemble the flue after
cleaning and inspection.

Just use little short self tapping screws, Steve. One per joint is
really adequate, unless you've got some horizontal distance that's
unsupported. I don't know of anything that'll "seal" the joints
reliably, short of welding them, because of the constant expansion and
contraction.

Trevor is dead right. the seal is unimportant.
as soon as there is hot air rising through the pipe any not perfectly
sealed joint will only be sucking room air INTO it not out.

Basically once the draft is established the hot air rising up through
the chimney is MOVING AIR. the air in the fireplace room (My rec
roomin my case) is static air that is barely moving at all at best.


Air in motion exerts less pressure thna air not moving so therefor the
non moving air will flow INTO the imperfectly sealed single wall stove
pipe joint and go up the chimney. In itself that is actually
desirable. it is less efficient as a means of heating BUT it makes it
impossible for carbon monoxide to enter the house. Unless i'm stoking
the fire i cannot smell my woodstove because all the airflow having
combustion applied to it is being fed up and out.

I love the fireplace smoke smell but i like living
my driveway and porch smell like my fire my house does not due to the
partially burned products not entering the house itself
