General Information Assembling Vent Pipes
Canadian Installations:
Venting system must be installed in accordance with
the current CSA-B149.1 installation code.
USA Installations:
The venting system must conform with local codes
and/or current National Fuel Gas Code ANSI Z223.1/
NFPA 54.
Only venting components manufactured by CFM
Corporation can be used in Direct Vent systems.
Twist Lock Pipes
When using twist-lock pipe, it is not necessary to use
sealant on the 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 sliding joints of telescopic vent sec-
tions used in the system.
To join the twist lock pipes together, align the beads of
the male end with the grooves of the female end. While
bringing the pipes together, twist 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.
NOTE: For ease of assembly, use a lubricant (Vaseline
or similar substance) on male end of twist lock pipe
prior to assembly.
