Installing Vent Pipe (DVP 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 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 confi rm it has locked.
Commercial, Multi-family (Multi-level exceeding two sto-
ries), or High-Rise Applications
All outer pipe joints must be sealed with high temperature
silicone (300ºF minimum continuous exposure rating), in-
cluding the slip section that connects directly to the hori-
zontal termination cap.
• Apply a bead of silicone sealant (300ºF minimum con-
tinuous exposure rating) 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.
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 confi 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.
