Diagram 11: The upper half of the fl ashing is
installed under the roofi ng material and not
nailed down until the chimney is installed. This
allows for small adjustments.
4)
Assemble the desired lengths of black pipe
and elbows necessary to reach from the
appliance adaptor up though the Round
Support Box. Insure that all pipes and elbow
connections are in the fully twist-locked
position and sealed.
5)
Cut a hole in the roof centred on the small
drilled hole placed in the roof in Step 2. The
hole should be of suffi cient size to meet
the minimum requirements for clearance
to combustibles of 1-1/4" (32mm) . Slip the
fl ashing under the shingles (shingles should
overlap half the fl ashing) as per diagram
11.
Diagram 12
7)
Ensure
fl ue 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.
6)
Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic to
avoid obstructions, it is important to
support the fl ue pipe every 3 feet, to
avoid excessive stress on the elbows,
and possible separation. Wall straps
are available for this purpose. See
diagram 7.
Galvanized pipe and elbows may be utilized
in the attic as well as above the roofl ine.
The galvanized fi nish is desirable above the
roofl ine due to its higher corrosion resist-
ance.
Continue to add pipe sections through the
fl ashing until the height of the fl ue cap meets
the minimum height requirements specifi ed
in diagram 12 or local codes. Note that for
steep roof pitches, the vertical height must
be increased. A poor draft, or down drafting
can result from high wind conditions near
big trees or adjoining roof lines, in these
cases, increasing the fl ue height may solve
the problem.

TERMINATION
1)
Maintain the 1-1/4" (32mm)
clearances (air spaces) to
combustibles when passing
through ceilings, walls, roofs,
enclosures, attic rafter, or other
nearby combustible surfaces.
Do not pack air spaces with
insulation. Check page 9
for the maximum vertical
rise of the fl uing system and
the maximum horizontal offset
limitations.
3)
To install the Round Support Box/Wall Thim-
ble in a fl at ceiling, cut a 254mm square hole
in the ceiling centred on the hole drilled in
Step 2. Frame the hole as shown in diagram
10.
INSTALLATION
7)
Install the Wall Thimble in the center of
the 254mm square and attach with wood
screws.
8)
Slide the decorative wall thimble up to the
wall surface being careful not to scratch
the paint and attach with screws provided.
Apply decorative brass or chrome trim if
desired. See diagram 7.
2)
Set the gas appliance in
its desired location. Drop a
plumb bob down from the
ceiling to the position of
the appliance fl ue exit, and
mark the location where
the fl ue will penetrate the
ceiling. Drill a small hole
at his point. Next, drop a
plumb bob from the roof
to the hole previously drilled
in the ceiling, and mark the spot where the
fl ue will penetrate the roof. Determine if
ceiling joists, roof rafters or other framing
will obstruct the fl uing system. You may
wish to relocate the appliance or to offset,
as shown in diagram 9 to avoid cutting load
bearing members.
