Diagram 3
Note:
a) The horizontal run of fl ue should have
a 1/4 inch rise for every 1 foot of run
towards the termination. Never allow the
fl ue to run downward. This could cause
high temperatures and may present the
possibility of a fi re.
b) The location of the horizontal fl ue termi-
nation on an exterior wall must meet all
local and national building codes, and
must not be blocked or obstructed. For
External Flue Terminal Locations, see
diagram on page 9.
4) If installing the fl ue termination to a wall with
vinyl siding, the Vinyl Siding Standoff must
be used. Attach the Vinyl Siding Standoff to
the Horizontal Flue Termination, but fi rst run
a bead of non-hardening mastic around its
outside edges, so as to make a seal between
fl ue cap and the standoff. Install the Vinyl
Siding Standoff (Part # 950) between the
fl ue cap and the exterior wall and attach
with the four wood screws provided. Seal
around the Vinyl Siding Standoff on all four
sides. Diagram 6. The arrow on the fl ue
cap should be pointing up. Insure that the
32mm clearances to combustible materials
are maintained. See diagram 4.
Note: If installing termination on a siding
covered wall, a vinyl siding standoff or
furring strips must be used to ensure
that the termination is not recessed
into the siding. The four wood screws
provided should be replaced with ap-
propriate fasteners for stucco, brick,
concrete, or other types of sidings.
5) Before connecting the horizontal run of fl ue
pipe to the fl ue termination, slide the black
decorative wall thimble cover over the fl ue
pipe, then slide the Wall Thimble (Part #
942) over the fl ue pipe.

6) Slide the appliance and fl ue assembly
towards the wall carefully inserting the
fl ue pipe into the fl ue cap assembly. It is
important that the fl ue pipe extends into
the fl ue cap a suffi cient distance so as to
result in a minimum pipe overlap of 32mm.
Secure the connection between the fl ue
pipe and the fl ue cap by attaching the two
sheet metal strips extending from the fl ue
cap assembly into the outer wall of the
fl ue pipe. Use the two sheet metal screws
provided to connect the strips to the pipe.
Bend any remaining portion of the sheet
metal strip back towards the fl ue cap, so
it will be concealed by the decorative wall
thimble cover. See diagram 5.

7) Install 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 6.

INSTALLATION
DURA-VENT VERTICAL
TERMINATION
1) Maintain the 32mm clearances (air spaces)
to combustibles when passing through ceil-
ings, walls, roofs, enclosures, attic rafter,
or other nearby combustible surfaces. Do
not pack air spaces with insulation. Check
page 10 for the maximum vertical rise of the
fl ueing 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 ceil-
ing, 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 ueing system. You may wish to relocate the
appliance or to offset, as shown in diagram
8 to avoid cutting load bearing members.
3) To install the Round Support Box/Wall
Thimble 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 9.
