specified for vinyl or non-vinyl siding and soffits. 1. There must be a 3' (914 mm) minimum between termination caps. 2. 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.

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.

Castings Group 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 sliding joints of telescopic vent
sections 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.
