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
replaced 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 framed
hole and attach with wood screws (Diagram 7).
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 Approved Vent 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.

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
in drafting or performance issues not
covered under warranty. Silicone (red
RTV) is optional.

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 square hole.-see chart to left
for size. The center of the square hole should
line up with the center-line of the horizontal pipe.
Cut and frame the square hole in the exterior
wall where the vent will be terminated. See
diagram 2 for center line requirements.
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,
5) Assemble the desired combination of pipe and
elbows to the appliance adaptor and twist-lock
for a solid connection.

(Rigid Vent Systems)
Below are the recommended framing dimensions
(inside measurements) for the 4" x 6-5/8"
rigid vent terminations - for use with a fi restop or
wall thimble.
* Clearances noted below 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 clearance to 1-1/2" (38mm).
