INSTALLATION

7) Ensure that the pipe clearances to
combustible materials are maintained
(Diagram 5). Install the termination cap.
Note: If installing termination on a vinyl
siding covered wall, a vinyl siding
standoff or furring strips must be used
to ensure that the termination is not
recessed into the siding.
The four wood screws provided should be re-
placed with appropriate fasteners for stucco,
brick, concrete, or other types of sidings.
8) Before connecting the horizontal run of vent
pipe to the vent termination, slide the Wall
Thimble over the vent pipe. The wall thimble
is required for all horizontal terminations.
9) Slide the appliance and vent assembly
towards the wall carefully inserting the vent
pipe into the vent cap assembly. It is important
that the vent pipe extends into the vent cap
suffi cient distance so as to result in a minimum
pipe overlap of 1-1/4 inches (32mm). Secure
the connection between the vent pipe and
the vent cap.
10) Install wall thimble in the center of the 11"
(279mm) square and attach with wood screws
(Diagram 7).
UNIT INSTALLATION
WITH HORIZONTAL
TERMINATION USING
5" X 8" VENTING
(Rigid Vent Systems)
Note: 5" x 8" venting is limited to vent
confi gurations found on page 17 of this
manual.
A top clearance of 2"(51mm) and side & bottom
clearance of 1-1/2"(38mm) must be maintained;
except when passing through a wall, ceiling, or
at the termination where the use of a fi restop
or wall thimble reduces the required clearance
to 1-1/2" (38mm). We recommend framing a
11"(279mm) x 11"(279mm) (inside dimensions)
hole to give structural rigidity for mounting the
termination.
Install the vent system according to the
manufacturer's instructions included with the
components.
1) Set the unit in its desired location. Check to
determine if wall studs or roof rafters are in
the way when the venting system is attached.
If this is the case, you may want to adjust the
location of the unit. Rough in the gas preferably
on the right side of the unit and the electrical
(junction block is on the left side) on the left.
2) Direct Vent pipe and fi ttings are designed with
special twist-lock connections to connect the
venting system to the appliance fl ue outlet. A
twist-lock appliance adaptor is required.
3) In conjunction with the Simpson Direct Vent
Pro system, install the adaptor after the unit is
set in its desired location. Put a bead of high
temperature silicone inside the outer section
of the adapter and a bead of Mill Pack on the
inner collar. Slip the adapter over the existing
inner and outer fl ue collar. Fasten to the outer
collar only with the 3 supplied screws (drilling
pilot holes will make this easier).
4) Level the fi replace and fasten it to the framing
using nails or screws through the top and side
nailing strips.
5) Assemble the desired combination of pipe and
elbows to the appliance adaptor and twist-lock
for a solid connection.
Note: For best results and optimum performance
with each approved venting system, it is
highly recommended to apply “Mill-Pac”
sealant (supplied) to every inner pipe
connection. Failure to do so may result
Diagram 1
Horizontal runs of vent must be supported every
3 feet (0.9meter). Wall straps are available for
this purpose.
6) Mark the wall for a 11" x 11" (279mm x 279mm)
square hole. The center of the square hole
should line up with the center-line of the
horizontal pipe. Cut and frame the 11 inch
(279mm) square hole in the exterior wall where
the vent will be terminated. See diagram 2 for
center line requirements.
Diagram 2
If the wall being penetrated is constructed of
non-combustible material, i.e. masonry block
or concrete, an 8" (203mm) diameter hole is
acceptable.
Note:
a) The horizontal run of vent must be level, or
have a 1/4 inch rise for every 1 foot of run
towards the termination. Never allow the
vent to run downward. This could cause
high temperatures and may present the
possibility of a fi re.
b) The location of the horizontal vent
termination on an exterior wall must meet
all local and national building codes, and
must not be blocked or obstructed. See
"Exterior Vent Termination Locations"
section for more details.
