C. Install Vent Piping Sections
General Notes:
1) The coaxial vent pipe sections are designed to fit tightly together and seal with the integral flue pipe seal and supplied
pipe clamps. No silicone caulk or special tools are required.
(2) All venting sections and fittings come complete with silicone flue pipe gaskets and outside gasketed pipe clamps
for making airtight connections between the venting pipe connections.
(3) Wetting the silicone gaskets with a solution of soapy water will make the pipe connections slide together easier.
(4) The internal flue pipe of the straight vent pipe is not fastened to the outside pipe so that the last vent section can be cut
to length. Remove the internal flue pipe from the outside pipe for easier handling during installation. Complete one
section at a time by installing the outside pipe, then the inside flue pipe.
Installation Procedure:
(a) Raise the outside vent pipe to the vent terminal connection with the flared (female) end of the pipe toward the
vent terminal. Insert the outside pipe into the vent terminal connection and grasp the end of the vent pipe while
twisting and pushing the pipe until inserted all the way into the vent terminal.
Figure 9
(b) Connect the outside pipes together using the gasketed clamps provided. The outside vent pipes have ribs
located on the female end. When connecting the vent piping, the gasketed clamps must cover the ribs and joints
of the connecting vent tubes (See Figure 10). Support each pipe section with hangers attached to supporting
joists in the wall or ceiling.

(c) Insert the inside flue pipe into the outer pipe with the female gasketed end toward the vent terminal. Push and
twist on the end of the flue pipe until the flue pipe from the vent terminal is completely seated inside the female
gasketed end.
