Venting and Chimneys
A. Assemble Vent Sections
(DVP Only)
Attach Vent to the Firebox Assembly
Note:
The end of the pipe sections with the lanced tabs
will face toward the appliance.
Attach the
fi
rst pipe section to the factory-installed 6 inch
pipe section:
• 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 con
fi
rm it has locked.
• Slide the gasket over the
fi
rst vent section and place it
fl
ush to the appliance. This will prevent cold air in
fi
ltration.
Secure with four screws. See Section 6.

Assemble Pipe Sections
Per Figure 7.2:
• Start the inner pipe on the lanced end of section A into
the
fl
ared 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
fi
rmly until
all lanced tabs lock into place.
• Lightly tug on the pipe to con
fi
rm the tabs have locked.
It is acceptable to use screws no longer than 1/2 inch (13
mm) to hold outer pipe sections together. If predrilling holes,
DO NOT
penetrate inner pipe.
For 90º and 45º elbows that are changing the vent direction
from horizontal to vertical, one screw minimum should be
put in the outer
fl
ue at the horizontal elbow joint to prevent
the elbow from rotating. Use screws no longer than 1/2
inch (13 mm). If predrilling screw holes,
DO NOT
penetrate
inner pipe.
All outer pipe joints must be sealed with 100% silicone
(300º F minimum continuous exposure rating) or alumi-
num foil duct tape, including the slip section that connects
directly to the horizontal termination cap.
• Apply a bead of silicone sealant (300º F minimum con-
tinuous exposure rating) inside the female outer pipe
joint prior to joining sections. See Figure 7.1.
• Only outer pipes need to be sealed. All unit collar, pipe,
slip section, elbow and cap outer
fl
ues 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, vent
could leak.

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