INSTALLATION

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.

DURA-FLUE VERTICAL
TERMINATION
1) Maintain the 1-1/4" clearances
(air spaces) to combustibles
when passing through ceil-
ings, walls, roofs, enclo-
sures, 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.
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.

3) To install the Round Support Box/Wall Thim-
ble in a fl at ceiling, cut a 10 inch square hole
in the ceiling centred on the hole drilled in
Step 2. Frame the hole as shown in diagram
10.
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". Slip the fl ashing
under the shingles (shingles should overlap
half the fl ashing) as per diagram 11.

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.

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.

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.
Notes:
a) For multistorey vertical installations, a
Ceiling Fire stop (Part # 963) is required
at the second fl oor, and any subsequent
fl oor. Diagram 13. The opening should
