General Information on Assembling Vent Pipes
Canadian Installations:
The 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 the
current National Fuel Gas code ANSI Z3.1/NFPA 54.
Only venting components manufactured by Vermont Cast-
ings Group can be used in Direct Vent systems.
Twist Lock Pipes
When using Vermont Castings Group 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 stove
and termination, and the sliding joint of any telescopic vent
section used in the system.

Termination clearances.
To join the twist lock pipes together, simply align the beads
of the male end with the grooves of the female end, then
while bringing the ends 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.
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 prior to assembly.

*NOTE:
Termination in an alcove space (spaces open only on one side and with an overhang) is permitted with the dimensions
specified for vinyl or non-vinyl siding and soffits. 1. There must be a 3’ (914 mm) minimum between termination caps. . All
mechanical air intakes within 10’ (1 m) of a termination cap must be a minimum of 3’ (914 mm) below the termination cap. 3. All
gravity air intakes within 3’ (914 mm) of a termination cap must be a minimum of 1’ (305 mm) below the termination cap.
