1. Locate the unit in the framing, rough in the
gas (preferably on the right side of the unit).
Locate the centerline of the termination and
mark wall accordingly. Cut an square hole in
the wall - see chart (inside dimension).
Note: If installing termination on a sid-
ing covered wall, a vinyl siding
standoff or vinyl furring strips
must be used to ensure that the
termination is not recessed into
the siding.

Venting (Flex Vent Systems)
NOTE: Horizontal sections must be sup-
ported at intervals not exceeding 3
feet (0.9 meter). (Flame picture and
performance will be affected by sags
in the liner).
4. Separate the 2 halves of the wall thimble and
securely fasten the one with the tabs to the
outside wall making sure that the tabs are
on top and bottom. Fasten the other thimble
half to the inside wall. The thimble halves slip
inside each other and can be adjusted for 2
x 4 (or 2 x 6) walls.
5. Slip the assembled liner and termination
assembly through the thimble making sure
the termination cap faces up (there are
markings on the cap that show which way
is up). This will position the termination cap
with 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
fireplace. (You may wish to cut the liner
shorter to make it more workable.) Do not
bend liner more than 90
o
.
The liners must
slip over the collars a minimum of 1-3/8".
7. Apply Mill-Pac over the fireplace inner flue
collar and slip the inner flex liner down over
it and attach with 3 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.
IMPORTANT: Do not locate termination
hood where excessive snow or ice
buildup may occur. Be sure to check vent
termination area after snow falls, and clear
to prevent accidental blockage of venting
system. When using snow blowers, make
sure snow is not directed towards vent
termination area.
* 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" (38mm).

Below are the recommended framing
dimensions (inside measurements) for the
5" x 8" rigid vent terminations - for use with a
firestop or wall thimble.
IMPORTANT
Must use Rear Venting Deflector
packaged with unit in rear vent
horizontal termination applications.
2. Level the fireplace and fasten it to the fram-
ing using nails or screws through the nailing
strips.
3. Assemble the vent assembly by applying
Mill-Pac to the inner flue collar of the ter-
mination and slipping the inner flex liner
over it at least 1-3/8" (35mm). Fasten with
the 3 screws (drilling pilot holes will make
this easier). Apply Mill-Pac to the outer flex
pipe and slip it over the outer flue collar of
the vent terminal at least 1-3/8"(35mm) and
fasten with the 3 screws.
