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 first 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 confirm it has locked.

Assemble Pipe Sections
Per Figure 10.2:
• 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 1/2 in. (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 vent 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 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 high temperature

silicone, 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 10.1

• 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, vent

may leak.

Note:

Make sure that the seams are not aligned to prevent

unintentional disconnection.
