E. Assemble Flue Pipe Sections (DVP Pipe
Only)
Attach Flue Pipe to the Firebox Assembly
Note:
The end of the pipe sections with the lanced tabs will face
toward the appliance.
Attach the first pipe section to the starting collar:
• Lanced pipe end of the starting collar
• Inner pipe over inner collar
• Push the pipe section until all lanced tabs snap in place
• Lightly tug on pipe to confirm it has locked.

Assemble Pipe Sections (DVP Pipe Only)
Per Figure 34:
• Start the inner pipe on the lanced end of section A into
the flared end of section B.
• Start the outer pipe of section A over the outer pipe of
section B.
• Once both vents sections are started, push firmly until
all lanced tabs lock into place.
• Lightly tug on the pipe to confirm the tabs have locked.
It is acceptable to use screws no longer than 13 mm to
hold outer pipe sections together. If predrilling holes,
DO
NOT
penetrate inner pipe.
For 90° and 45° elbows that are changing the flue pipe
direction from horizontal to vertical, one screw minimum
should be put in the outer flue at the horizontal elbow joint
to prevent the elbow from rotating. Use screws no longer
than 13 mm. If predrilling screw holes,
DO NOT
penetrate
inner pipe.

All outer pipe joints must be sealed with high temperature
silicone (with a minimum of 149 °C continuous exposure
rating), including the slip section that connects directly to
the horizontal termination cap.
• Apply a bead of silicone sealant inside the female outer
pipe joint prior to joining sections. See Figure 33
• Only outer pipes need to be sealed. All unit collar, pipe,
slip section, elbow and cap outer flues shall be sealed
in this manner, unless otherwise stated.
warNiNG! risk of fire or explosion! DO NOT
break
silicone seals on slip sections. Use care when remov-
ing termination cap from slip pipe. If slip section seals
are broken during removal of the termination cap, flue
pipe may leak.

Note:
Make sure that the seams are not aligned to prevent
unintentional disconnection.
