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 5"(127mm) liner and outer
8"(203mm) liner out enough to slip over
the fl ue collars of the fi replace. (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 fi replace inner collar
and slip the 5"(127mm) liner down over it
and attach with 3 supplied screws.
8) Do the same with the 8"(203mm) 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.
UNIT INSTALLATION
HORIZONTAL TERMINATION
WITH FLEX VENT SYSTEM
Note: A top clearance of 3"(76mm) and
side & bottom clearance of 2"(51mm)
must be maintained; except when
passing through a wall, ceiling, or
at the termination where the use of
a fi restop or wall thimble reduces the
required clearance to 1-1/2" (38mm).
We recommend framing a 11"(279mm)
x 11"(279mm) (inside dimensions)
hole to give structural rigidity for
mounting the termination.
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 11"(279mm)
hole in the wall (inside dimension).
Note: If installing termination on a siding
covered wall, a vinyl siding standoff
or vinyl furring strips must be used
to ensure that the termination is not
recessed into the siding.
2) Level the fi replace 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 5"(127mm) inner collar of
the termination and slipping the 5"(127mm)
liner over it at least 1-3/8" (35mm). Fasten
with the 3 screws (drilling pilot holes will
make this easier). Apply Mill Pac or high
temperature silicone to the 8"(203mm) fl ex
pipe and slip it over the 8" outer collar of
the vent terminal at least 1-3/8"(35mm) and
fasten with the 3 screws.
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).
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.
