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
firestop 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 cov-
ered 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 fireplace 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 5"(127mm) inner collar of the termina-
tion 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). Ap-
ply Mill Pac or high temperature silicone to the
8"(203mm) flex 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 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.
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 flue
collars of the fireplace. (You may wish to cut
the liner shorter to make it more workable.) Do
not bend liner more than 90
slip over the collars a minimum of 1-3/8".
7) Apply Mill Pac over the fireplace 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.
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.
