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.
2) Assemble the desired combination
of pipe and elbows to the appliance
and ensure seal wil Mil-Pac.
Note: Apply sealant "Mill-Pac" to inner
pipe and high temperature
silicone sealant to outer pipe on
every joint.
b) Horizontal runs of flue must be
supported every three feet. Wall
straps are available for this purpose.
3) Mark the wall for a 254mm x 254mm
square hole. The center of the
square hole should line up with the
centerline 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 diameter (191mm dia. for
flex) hole is acceptable.
See Horizontal Termination diagram
on page 13.
Note:
a) The horizontal run of flue must
be level, or have a 6mm for
every 300mm of 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.

c) Snorkel Terminations:
For installations requiring a
vertical rise on the exterior of
the building, 355mm Riser Flue
as shown in Dia. 2a. Follow the
same installation procedures
as used for standard Horizontal
Termination. NEVER install the
snorkel upside down.
Do not attempt to enclose the
Snorkel within the wall, or any
other type of enclosure.
Dia. 2a
*As specified in CGA B149 Installation
Code. Local codes or regulations may
require different clearances.
4) The arrow on the flue cap should
be pointing up. Insure that the
40mm clearances to combustible
materials are maintained (Dia. 3).
Install the termination cap.

The four wood screws provided should
be replaced with appropriate fasteners
for stucco, brick, concrete, or other
types of sidings.
See
Note: If installing termination on a
siding covered wall, a vinyl siding
standoff or furring strips must be
used to ensure
termination is not recessed into
the siding.
5) Before connecting the horizontal
run of flue pipe to the flue
termination, slide the Wall Thimble
over the flue pipe.
6) 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 with 3 sheet metal screws.
WARNING:
When installing in a high
wind situation, common
sense must prevail.
Choose a sheltered side
of the house.
A non-combustible water
ingress shelf will need to
be fitted 200mm above
the terminal to prevent
water ingress in extreme
conditions or where no
sofit shelters the
terminal.
