Install
the flue
system
according
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) Simpson Dura Vent 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 Simpson Direct Vent
Pro system, install the adaptor after the unit
is set in its desired location. Put a bead of Mill
Pac inside the outer section of the adapter and
a bead of Mill Pac 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 flue outlets and secure.
Note: For best results and optimum performance
with each approved venting system, it is
highly recommended to apply "Mill-Pac"
sealant to every inner pipe connection.
Failure to do so may result in drafting or
performance issues not covered under
warranty.
Horizontal runs of vent must be supported
every 0.9 metre. 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
acceptable.
Note:
to
the
a) The horizontal run of vent must have a
6mm rise for every 305mm of run towards
the termination. Never allow the vent to
run downward. This could cause high
temperatures and may present the possibility
of a fire.
b) The location of the horizontal vent
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 3). Install
the termination cap.
Note: If installing termination on a siding
covered wall, a siding standoff or furring
strips must be used to ensure that the
termination is not recessed into the
siding.
Diagram 3
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 sufficient distance
so as to result in a minimum pipe overlap of
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 4).
