installation
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: 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.

8. Before connecting the horizontal run of vent pipe
to the vent termination, slide the Wall Thimble
over the vent pipe. The wall thimble is required
for all horizontal terminations.
9. Slide the appliance and vent assembly towards
the wall carefully inserting the vent pipe into the
vent cap assembly. It is important that the vent
pipe extends into the vent cap sufficient distance
so as to result in a minimum pipe overlap of
1-1/4 inches (32mm). Secure the connection
between the vent pipe and the vent cap.
10. Install wall thimble in the center of the framed
hole and attach with wood screws (Diagram 4).

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 inner and outer flex 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
o
.
The liners must slip over the
collars a minimum of 1-3/8".
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
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 firestop or wall
thimble reduces clearance to 1-1/2" (38mm).

Below are the recommended framing dimensions
(inside measurements) for the 5" x 8" flex vent
terminations - for use with a firestop or wall
thimble.
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 1-3/8"
(35mm). Fasten with the 3 screws (drilling pilot
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 1-3/8"(35mm)
and fasten with the 3 screws.
