Install the flue 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 flueing 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 Flue pipe and fittings are designed with
special twist-lock connections to connect the
flueing system to the appliance flue outlet. A
twist-lock appliance adaptor is required.
3) In conjunction with the Approved Flue 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
flue collar. Fasten to the outer collar only with
the 3 supplied screws (drilling pilot holes will
make this easier).
4) Level the fireplace 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
flueing 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.
Horizontal runs of flue 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 flue will be terminated. See diagram
4" x 6-5/8"
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 flue must be level, or
have a 1/4 inch rise for every 1 foot of run
towards the termination. Never allow the
flue to run downward. This could cause
high temperatures and may present the
possibility of a fire.
b) The location of the horizontal flue termination
on an exterior wall must meet all local and
national building codes,

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 flue pipe
to the flue termination, slide the Wall Thimble
over the flue pipe. The wall thimble is required
for all horizontal terminations.
9) Slide the appliance and flue assembly towards
the wall carefully inserting the flue pipe into the
flue cap assembly. It is important that the flue
pipe extends into the flue cap sufficient distance
so as to result in a minimum pipe overlap of
1-1/4 inches (32mm). Secure the connection
between the flue pipe and the flue cap.
10) Install wall thimble in the center of the framed
hole and attach with wood screws (Diagram 7).
