HORIZONTAL INSTALLATIONS
Install the flue system according to
the manufacturer's instructions
included with the components.
1) Set the unit in its desired location.
Check to determine if wall studs or
roof rafters are in the way when the
flueing system is attached. If this is
the case, you may want to adjust
the location of the unit. Rough in
the gas preferably on the right side
of the unit and the electrical (junction
block is on the left side) on the left.
Note: Apply sealant "Mill-Pac" to inner
pipe and high temperature
silicone sealant to outer pipe on
every joint.
a) Horizontal runs of flue must be
supported every three feet.
2) Mark the wall for a 254mm x 254mm
square hole. The centre of the
square hole should line up with the
centreline of the horizontal pipe.
Cut and frame the 254mm square
hole in the exterior wall where the
flue will be terminated. If the wall
being penetrated is constructed of
non-combustible material, i.e.
masonry block or concrete, a
(178mm dia. 191mm dia. for flex)
hole is acceptable.
Note:
a) The horizontal run of flue must
have a 6mm rise for every
305mm run towards the
termination. Never allow the flue
to run downward. This could
cause high temperatures and
may present the possibility of a
fire.
b) The location of the horizontal
flue termination on an exterior
wall must meet all local and
national building codes, and
must not be blocked or
obstructed. For External Flue
Terminal Locations.

Note:
Riser Vent is only
for use in above
grade terminations

3) The arrow on the flue cap should
be pointing up. Insure that the
40mm clearances to combustible
materials are maintained. Install
the termination cap, diagram 5.
The four wood screws provided
should be replaced
appropriate fasteners for stucco,
brick, concrete, or other types of
sidings.
Note: If installing termination on a
siding covered wall, a vinyl
siding standoff or furring strips
Diagram 3
must be used to ensure that the
termination is not recessed into
the siding.
4) Before connecting the horizontal
run of flue pipe to the flue
termination, slide the Wall Thimble
over the flue pipe.
5) Slide the appliance and flue
assembly towards the wall carefully
inserting the flue pipe into the flue
cap assembly. It is important that
the flue pipe extends into the flue
cap sufficient distance so as to
result in a minimum pipe overlap of
32mm. Secure the connection
between the flue pipe and the flue
cap by attaching the two sheet
metal strips extending from the flue
cap assembly into the outer wall of
the flue pipe. Use the two sheet
metal screws provided to connect
the strips to the pipe section. See
Diagram 4.
