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
).

WARNING
• Ensure vent components are locked together correctly.
• Pipe may separate if not properly joined.
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.
Burn Risk.
•
Local codes may require installation of a
cap shield to prevent anything or anyone
from touching the hot cap.
WARNING
Step 1.
Check the installation instructions for required 1 in. (25mm)
clearances (air space) to combustibles when passing
through ceilings, walls, roofs, enclosures, attic rafters, or
other nearby combustible surfaces. See page 17,
Figure
5.15.
Check the instructions below for maximum vertical rise
of the venting system, and any maximum horizontal offset
limitations. All offsets must fall within the set parameters of
the vent graph (
Figure 5.2
) located on page 12.
NOTE:
Maximum vertical rise allowable is 35 ft. (11m),
Figure 5.11
.
NOTE
: Maximum number of 45° elbows permitted for
a vertical installation is eight, provided their installation
does not decrease maximum allowable horizontal run (as
specified by vent graph, on page 12).
