B. Assemble Vent Sections (SLP Only)

To attach the first vent component to the starting collars of the appliance

•Attach a DVP-SLP24 adapter to the starting collar of the appliance.

•Lock the vent components into place by sliding the pipe section onto the collar.

•Align the seam of the pipe and seam of collar to allow engagement. Rotate the vent component to lock into place. Use this procedure for all vent components. See Figure 10.5.

•Slide the gasket over the first vent section and place it flush to the appliance. This will prevent cold air infiltration. Caulk with a minimum of 300ºF continuous exposure rating may be used to hold the part in place.

•Continue adding vent components, locking each succeeding component into place.

•Ensure that each succeeding vent component is securely fitted and locked into the preceding component.

Commercial, Multi-family (Multi-level exceeding two stories), or High-Rise Applications

For Installation into a commercial, multi-family (multi-level exceeding two stories) 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 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.

C. Assemble Slip Sections

WARNING! Risk of Fire or Asphyxiation! Overlap pipe sections at least 1 1/2 in. (38 mm). Secure slip sections with two screws which must not exceed 1/2 in. (13 mm) in length. Use the pilot holes. Pipe could separate if not properly joined.

•Slide the inner flue of the slip section into the inner flue of the pipe section and the outer flue of the slip section over the outer flue of the pipe section. See Figure 10.6.

•Slide together to the desired length.

Figure 10.6 Slip Section Pilot Holes

•Maintain a 1-1/2 in. (38 mm) overlap between the slip section and the pipe section.

•Secure the pipe and slip section with two screws no longer than 1/2 in. (13 mm), using the pilot holes in the slip section. See Figure 10.7.

Figure 10.7 Screws into Slip Section

•Continue adding pipe as necessary following instructions in “Assemble Pipe Sections.”

NOTICE: If slip section is too long, the inner and outer flues of the slip section can be cut to the desired length.

NOTICE: When installing a vent system with an HRC termination cap, all pipe system joints shall be sealed using silicone with a minimum of 300ºF continuous exposure rating.

•Apply a bead of silicone sealant inside the female outer pipe joint prior to joining sections.

•Only outer pipes are sealed, sealing the inner flue is not required.

•All unit collar, pipe, slip section, elbow and cap outer flues shall be sealed.
