inside each other and can be adjusted for
2 x 4 or 2 x 6 walls. The liners must slip
over the collars a minimum of 1-3/8".
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 4"(100mm) liner and outer
6-7/8"(175mm) 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 45
o
.
7) Apply Mill Pac over the fireplace inner collar
and slip the 4"(100mm) liner down over it
and attach with 3 supplied screws.
8) Do the same with the 6-7/8"(175mm) liner.
9) Apply a bead of silicone between the thim-
ble 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 build-
up may occur. Be sure to check flue termi-
nation area after snow falls, and clear to
prevent accidental blockage of flueing
system. When using snow blowers, make
sure snow is not directed towards flue
termination area.
Note: To make the
installation more
aesthetically pleas-
ing, we recom-
mend framing out a
square to mount
the terminal to.
be used to ensure that the termi-
nation is not recessed into the
siding.
2) Level the fireplace and fasten it to the
framing using nails or screws through the
nailing strips.
3) Assemble the flue assembly by applying Mill
Pac to the 4"(100mm) inner collar of the
termination and slipping the 4"(100mm) 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 temper-
ature silicone to the 6-7/8"(175mm) flex pipe
and slip it over the 6-7/8" outer collar of the
flue terminal at least 1-3/8"(35mm) and fas-
ten 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).
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
roof pitches, the vertical height must be
increased. A poor draft, or down drafting can
result from high wind conditions near big
trees or adjoining roof lines, in these cases,
increasing the flue height may solve the
problem.
7) Ensure flue is vertical and secure the base
of the flashing to the roof with roofing rails,
slide storm collar over the pipe section and
seal with a mastic.
8) Install the vertical termination cap by twist-
locking it.
Note: Any closets or storage spaces,
which the flue passes through
must be enclosed.

1) Locate the unit in the framing, rough in the
gas. Locate the centerline of the termina-
tion and mark wall accordingly. Cut a
10"(254mm) hole in the wall (inside dimen-
sion).
Note: A 1-1/2"(38mm) clearance around
the liner must be maintained ex-
cept that only a 1" (25mm) clear-
ance is needed at the termination
end. We recommend framing a
10"(254mm) x 10"(254mm) (inside
dimensions) hole to give struc-
tural rigidity for mounting the ter-
mination.
Note: If installing termination on a siding
covered wall, furring strips must
