Before joining elbows and pipes apply a bead of high
temperature sealant to the crimped end of the elbow or
pipe. Join the pipes using a 2” (50mm) overlap and
secure the joints with three (3) sheet metal screws
(Fig. 11). Wipe off excess sealant.
There are polished brass decorative
rings available to hide the exposed
piping joints. Wrap the brass ring over
the joint fitting the stud into the notch
and tighten down the 3/8” nut.

TWIST LOCK PIPES
When using twist-lock pipe it is not necessary to use
sealant on the twist lock joints.
The only areas of the venting system that need to be
sealed with high temperature silicone sealant are the
collars on the fireplace and termination, and the sliding
joint of any telescopic vent section used in the system.
To join the twist lock pipes together, simply align the
beads of the male end with the grooves of the female
end, twisting the pipe until the flange on the female
end contacts the external flange on the male end.
It is recommended that you secure the joints with three
(3) sheet metal screws, however this is not mandatory
with twist lock pipe.
To make it easier to assemble the joints we suggest
putting a lubricant (Vaseline or similar) on the male
end of the twist lock pipe.
