steep 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 fl ue height may solve
the problem.
7) Ensure fl ue is vertical and secure the base
of the fl ashing to the roof with roofi ng 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 fl ue passes through must be
enclosed.

PROCEDURES

Flue System (Flex)
1) Locate the unit in the framing, rough in
the gas. Locate the centerline of the ter-
mination 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 except
that only a 1" (25mm) clearance is
needed at the termination end. We
recommend framing a 10"(254mm)
x 10"(254mm) (inside dimensions)
hole to give structural rigidity for
mounting the termination.
Note: If installing termination on a siding
covered wall, furring strips must be
used to ensure that the termination
is not recessed into the siding.

Note: To make the
installation more
aesthetically pleas-
ing, we recommend
framing out a square
to mount the termi-
nal to.
2) Level the fi replace and fasten it to the fram-
ing using nails or screws through the nailing
strips.
3) Assemble the fl ue 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 temperature
silicone to the 6-7/8"(175mm) fl ex pipe and
slip it over the 6-7/8" outer collar of the fl ue
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).
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. The liners must slip
over the collars a minimum of 1-3/8".

INSTALLATION
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 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
45 o .
7) Apply Mill Pac over the fi replace 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 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 termina-
tion hood where excessive snow or ice
buildup may occur. Be sure to check fl ue
termination area after snow falls, and clear
to prevent accidental blockage of fl ueing
system. When using snow blowers, make
sure snow is not directed towards fl ue
termination area.
