3. When penetrating through stucco wall, install the counter
flashing. The counter flashing allows stucco, or other
materials, to be finished directly to the sides of the
termination cap. First attach the counter flashing to the
base of the horizontal termination cap with the small
screws provided, then mount entire assembly onto the wall
with the four (4) 2-1/2" (64 mm) wood screws provided.
Step 4 - Before connecting your horizontal pipe sections to
the horizontal termination cap, slide the wall thimble cover
over the pipe section nearest the interior side of wall, Figure
3.14.
Step 5 - Slide the appliance and vent assembly towards the
wall, carefully inserting the pipe section into the cap assembly.
It is important the pipe section extends into the back of the
termination cap with a minimum overlap of 1-1/4" (32 mm).
Use the two (2) sheet metal screws provided to secure the
pipe section to the back of the termination cap. The wall
thimble cover will cover the screw heads, Figure 3.30.

Step 1 - Check these installation instructions for required
clearances (air spaces) to combustibles when passing
through ceilings, walls, roofs, enclosures, attic rafters or
other nearby combustible surfaces. Do not pack air spaces
with insulation. Check these instructions for maximum
vertical rise of the venting system and any maximum
horizontal offset limitations.

Step 2 - Set the gas
appliance in the desire
location. Drop a plumb bob

flue exit, and mark the
location where the vent will
penetrate the ceiling. Drill a
small hole at this point. Next,
drop a plumb bob from the
roof to the hole previously
drilled in the ceiling, and
mark the spot where the
vent will penetrate the roof,
Figure 3.32. Determine if
ceiling joists, roof rafters,
framing or other materials
will obstruct the venting
system. You may wish to
relocate the appliance or to
offset, to avoid cutting load-
bearing members.
Step 3 - To install the round
ceiling support/wall thimble
cover in a flat ceiling, cut a
10" x 10" (254 x 254 mm)
square hole in the ceiling
(unless otherwise specified)
centered on the hole drilled
in Step 2. Frame the hole as shown in Figure 3.33.
Step 4 - Assemble the desired pipe sections and elbows
necessary to reach from the appliance adapter up through
the round ceiling cover or support box. Ensure that all pipe
and elbow connections are in their fully twist-locked position.
Step 5 - Cut a hole in the roof centered on the small drill
hole placed in the roof in Step 2. The opening should be
of sufficient size to meet the minimum requirements for
clearance to combustibles, as specified.
