Grecians, All.
Here's a question to all who have used a helical coiled culvert as their
chimney. I will be running the chimney through the roof through a metal,
conical flashing (...for lack of the proper term). In order to achieve a =
snug
fit around the culvert I would like to fill in it's grooves...producing a =
smooth
cylinder where it comes in contact with the conical flashing. Any ideas on =
what
type of product I might use to solve this problem?...Or better yet, are =
there
better solutions out there? I'm all ears, folks.
Thanks=21

John, I don't quite understand your description, terms are different in
different countries. The local regulations here require a double skin
chimney when piercing the roof ( with steel chimneys that is) and I sealed
mine with a conical rubber seal available here from plumbing supplies
dealers. The rubber cone is made of a high temperature silicon rubber. I'm
sure these would be available in the US.

Hi John,
What I have done is traced the helical pattern onto a square of sheet
metal. (of
course I did this before I put the chimney into place or used an old
cut off
section of the pipe) This square is sized to be big enough to keep the
rain out of my roof jack. I then cut this
hole out. That part is a royal pain in the neck. The
sheet metal will bounce all over the place if you use a jig saw or
reciprocating
saw. I ended up having to temporally screw it down onto a piece of ply
wood with a
hole cut where the trace was. That way it didn't bounce around so much,
but it was
still a pain. Any way after you have your pattern cut out, cut the
whole thing in
half or just one side from the outside edge into the hole, so you can
get it onto
your chimney. At this point it isn't a perfect fit by any means. I
then used a
torch to braze it into place onto the chimney. (be careful not to blow a
hole into
your chimney). I had to use some little cutouts (1"x1" for example) of
sheet metal as fill ins where
ever it didn't fit up so well. And smaller holes can be filled with
braze.
I hope this makes some sense. If not let me know and I'll try to explain
alittle more clearly.
It has worked well for me, but I am interested in what others have to
say also.
Over and out,

John, I approached a similar problem by cutting a circle collar of copper
and bending it(with a hammer) to the culvert shape and pop riviting it to
the metal 5v roof. The kiln shed is outside in the pasture and it has a
slanting roof. The copper was joined together on the low back side of the
culvert pipe. This process worked ok, however a little water does drip
through.
