(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 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.

Step 5.
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
the vent pipe. Use the two sheet metal screws provided to
connect the strips to the pipe section (Figure 5.9).
