installation-power vent
Install the vent system according to the manufacturer's
instructions, included with the components.
1. Set the unit in its desired location. Determine
whether 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 fittings are designed with
special twist-lock connections to connect the
venting system to the appliance flue 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 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.

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 centerline of the horizontal pipe.
Cut and frame the square hole in the exterior wall
where the vent will be terminated. See diagram
2 for centerline requirements.
5. Assemble the desired combination of pipe and
elbows to the appliance adaptor and twist-lock
for a solid connection.

with a firestop or wall thimble.

• For best results and optimum
performance with each approved
venting system, application of Mil-Pac
sealant (supplied) to every inner pipe
connection is recommended. Failure
to apply Mil-Pac may result in drafting
or performance issues not covered
under warranty.
• Horizontal vent runs must be supported
every 3 feet (0.9 m). Wall straps are
available for this purpose.
