INSTALLATION
can result from high wind conditions near big
trees or adjoining roof lines, in these cases,
increasing the vent height may solve the
problem.
7) Ensure vent 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 vent passes through must be
enclosed.

INSTALLATION
PROCEDURES
1) Locate the unit in the framing, rough in the
gas (preferably on the right side of the unit)
and the electrical (Junction block is on the
left side) on the left. Locate the centerline of
the termination and mark wall accordingly.
Cut a 10"(254mm) hole in the wall (inside
dimension).
Note: A 2" clearance at the top and 1 1/2"
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.

recommend framing
out a square to
mount the terminal
to.
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.
2) Level the fi replace and fasten it to the
framing using nails or screws through the
nailing strips.
3) Assemble the vent 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 vent terminal at least 1-
3/8"(35mm) and fasten with the 3 screws.
NOTE:
Horizontal sections must be
supported 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".
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
o
90
.
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 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.
