10 Install Vent Pipe

A. Assemble Pipe Sections (DVP Only)

Attach Pipe to the Firebox Assembly

Note: The end of the pipe sections with the lanced tabs will face towards 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.

Commercial, Multi-family (Multi-level exceeding two stories), 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 removing termination cap from slip pipe. If slip section seals are bro- ken 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 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.

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