1. Locate the unit in the framing and rough in the
gas, preferably on the right side of the unit.
Locate the centerline of the termination and
mark the wall accordingly. Cut a square hole
in the wall (see chart for inside dimension.)
2. Level the fireplace and fasten it to the framing
using nails or screws through the nailing strips.
3. Assemble the vent by applying Mill Pac to the
inner flue collar of the termination and slipping
the inner flex liner over by at least 1-3/8" (35mm)
over it. Fasten with the three screws (drilling
pilot holes will make this easier).
4. Apply Mill-Pac to the outer flex pipe and slip it
over the outer flue collar of the vent terminal
by at least 1-3/8"(35mm). Fasten with the three
screws.

5. Slip the assembled liner and termination as-
sembly through the thimble. Check the markings
on the termination cap to ensure it is facing up;
this will position the termination cap with the
proper down slope for draining water. Fasten
the cap to the outer wall with the 4 supplied
screws.
6. Pull the centre inner and outer flex liner out
enough to slip over the flue collars of the fire-
place a minimum of 1-3/8" (38 mm). You may
wish to cut the liner shorter to make it more
workable. Do not bend the liner more than 90°.
7. Apply Mill-Pac over the fireplace inner flue
collar and slip the inner flex liner down over it.
Attach with three supplied screws.
8. Do the same with the outer flue collar and outer
flex liner.
9. Apply a bead of silicone between the thimble
and termination and around the outer edge of
the terminal at the wall in order to keep the
water out.
* Clearances noted below must be maintained,
except when passing through a wall, ceiling, or at
the termination, where the use of a firestop or wall
thimble reduces clearance to 1-1/2" (38 mm).

• Do not locate termination hood
where excessive snow or ice buildup
may occur. Check vent termination
area after snowfalls and clear to
prevent blockage of the venting
system. When using snow blowers,
make sure snow is not directed
toward vent termination area.
