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 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 inner fl ue collar of the termi-
nation and slipping the inner fl ex liner over
it at least 1-3/8" (35mm). Fasten with the
3 screws (drilling pilot holes will make this

5" X 8" 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 wayis
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 fl ex 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 fl ue
collar and slip the inner fl ex liner down over
it and attach with 3 supplied screws.
8)
Do the same with the outer fl ue collar and
outer fl ex 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 fi restop or wall thimble
reduces clearance to 1-1/2" (38mm).
