(NOTE: Some termination caps may cause the vent pipe to be off center on flashing). Ensure that proper clearances to combustible materials are maintained. If you are not using an approved termination cap with a built-in vinyl siding standoff on a building with vinyl siding, a vinyl siding standoff should be installed between the termination cap and the exterior wall (Figure 5.8). Follow manufacturer’s instructions for attaching the vinyl siding standoff to the horizontal termination cap. The vinyl siding standoff prevents excessive heat from possibly melting the vinyl siding material. The vent terminal cap shall not be recessed into a wall or siding. Remove siding from the area where the standoff will be located.

Figure 5.9

Note: The attachment from the vent pipe to the vent termination cap must be sealed with silicone. Termination caps shall not be recessed into a wall or siding.

Place the wall thimble cover over the pipe assembly and slide the appliance and vent assembly towards the wall, carefully inserting the vent pipe into the vent termination cap assembly. It is important that the vent pipe extend into the vent termination cap a sufficient distance so as to result in a minimum pipe overlap of 1-1/4 in. (32mm). Secure the connection between the vent pipe and the vent termination cap by attaching the two sheet metal strips extending from the vent termination cap assembly into the outer wall of

touching the hot cap.
