ÎB. Assemble Vent Sections (SLP Pipe Only)

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

•Attach an SLP-DVP24 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. High temperature caulk 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 high temperature silicone, including the slip section that connects directly to the hori- zontal 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.

ÎC. Assemble MI Sections (DVP only)

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

MI (Minimum Installation) sections are non-unitized so that they can be cut to a specific length.

•Cut sections to length from the non-expanded end (see Figure 10.6). Maintain 1-1/2 in. (38 mm) overlap.

•Connect the expanded end of the MI inner flue with the inner flue of the adjacent pipe section and secure with three screws.

CAUTION! Risk of Fire! The expanded portion of the MI inner flue must overlap completely with the unexpanded end of the adjacent pipe section.

•Connect the cut end of the MI outer flue with the expanded end of the outer flue of the adjacent pipe section and secure with three screws.

•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.

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