lnstall 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 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 Ventsystem, install the adaptor after the unit is set in its desired location .
Put a bead of Mill-Pac inside the outer section of the adaptor and a bead of Mill-Pac on the inner collar . Slip
the adaptor 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) . This adaptor is typically factory installed .
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 pipes 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 in drafting or performance issues not covered under warranty .
! NOTE: Horizontal runs of vent must be supported every 3 ft (0 .9 m) .
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 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 center line requirements .
If the wall being penetrated is constructed of non-combustible material, i .e ., masonry block or concrete, an 8"
(203 mm) diameter hole is acceptable .

* Clearances noted must be maintained except when
passing through a wall, ceiling or at the termination
where the use of a fire stop or wall thimble reduces
clearance to 1-½" (38 mm) .
These are the recommended framing dimensions
(inside measurements) for the 5" x 8" (127 x 203 mm)
rigid vent terminations - for use with a fire stop or wall
thimble .
