Installing Vent Pipe (DVP and SLP Pipe)
A. Assemble Vent Sections (DVP Pipe 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 starting collar:
• Lanced pipe end to 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.

Assemble Pipe Sections
Per Figure 10.2:
• 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 in. (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
in. (13 mm). If predrilling screw holes,
DO NOT
penetrate
inner pipe.
Commercial, Multi-family (Multi-level exceeding two sto-
ries), or High-Rise Applications
All outer pipe joints must be sealed with silicone with a
minimum of 300ºF continuous exposure rating, including the
slip section that connects directly to the horizontal termi-
nation cap.
• Apply a bead of silicone sealant inside the female outer
pipe joint prior to joining sections. See Figure 10.1
• 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
may leak.

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