except when passing through a wall, ceiling or at
the termination where the use of a firestop or wall
thimble reduces clearance to 25mm.

Below are the recommended framing dimensions
(inside measurements) for the 102mm x 168mm

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 square hole in the wall - see
chart (inside dimension).
Note: I f 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 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 inner flue collar of the termination
and slipping the inner flex liner over it at least
35mm. Fasten with the 3 screws (drilling pilot
r i e u r
holes will make this easier). Apply Mill-Pac to

the outer flex pipe and slip it over the outer flue
collar of the vent terminal at least 35mm and
fasten with the 3 screws.

NOTE: Horizontal sections must be sup-
ported at intervals not exceeding
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 51mm x
102mm or 51mm x 152mm walls.
5. Slip the assembled liner and termination as-
sembly through the thimble making sure the
termination cap faces up (there are markings
on the cap indicating 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 inner and outer flex liner out
enough to slip over the flue collars of the fire-
place. (You may wish to cut the liner shorter
to make it more workable.) Do not bend liner
more than 90
collars a minimum of 35mm
7. Apply Mill Pac over the fireplace inner flue
collar and slip the inner flex liner down over it
and attach with 3 supplied screws.
8. Do the same with the outer flue collar and outer
flex 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

accidental blockage of flueing system. When
using snow blowers, make sure snow is not
