instaLLation oF venting anD teRminations:
Read all instructions carefully before starting the installation. Failure to follow these instructions may create a re
or other safety hazard, and will void the warranty.
INSTALLATION PRECAUTIONS:
• Do not install any damaged venting or vent components.
• Do not modify any vent or termination component.
• Do not install any vent component that is not an approved vent component for this appliance.
• Do not use any instructions other that those included in this manual or those included by the vent component
manufacturer with the venting. When there are discrepancies between the two, this manual will be considered
the nal authority.
Consult your local building codes before beginning the installation.
WARNING
• Always maintain required clearances (air spaces) to nearby combustibles to prevent a re hazard.
Do not ll air spaces with insulation. Unless stated otherwise, clearances on horizontal vent sections
are 2” (51mm) to combustible materials. Clearances to vertical vent sections are 1” (25mm) to
combustible clearances.
• The replace and vent system must be vented directly to the outside of the building. Each direct
vent replace must use its own separate vent system. Common vent systems are prohibited.
• The ow of combustion and ventilation air not be obstructed.
hoRiZontaL instaLLation:
Step 1. Set the replace in its desired location. Check to determine if wall studs or roof rafters are in the way when
the venting system is attached. If this is the case, you may want to adjust the location of the appliance.
Step 2. Direct Vent pipe and ttings are designed with special twist-lock connections. Assemble the desired
combination of pipe and elbows to the appliance. See the sections on Typical Framing - inTernal chase,
exTernal chase or corner insTallaTion for some of the possible vent pathway options. All installations must
fall within the Allowable Vent Congurations shown in Figure 21.
Notes:
(1) Twist-lock procedure: Four (4) indentations, located on the female
ends of pipes and ttings, are designed to slide straight onto
the male ends of adjacent pipes and ttings, by orienting the
four pipe indentations so they match and slide into the four (4)
entry slots on the male ends. Push the pipe sections completely
together, then twist-lock one section clockwise approximately
one-quarter turn, until the two (2) sections are fully locked.
(2) Horizontal runs of vent must be supported every 3 feet (915mm).
Wall Straps are available for this purpose.
(3) Sealant is only necessary on the outer tube of the GS Pipe. Run a
⅛ inch (3mm) wide bead of sealant around the male end of the
outer sleeve, as shown in Figure 27, and twist-lock the pipes or
ttings together.
Step 3. With the adaptor and pipe attached to the replace, slide the replace into its correct location, and mark
the wall for a rectangular hole of the appropriate size. Use 12.5”x14.75” (318x375mm) hole for 6” x 8-5/8”
pipe, Figure 28. The center of the hole should line up with the center line of the horizontal pipe, as shown
in Figure 30. Cut and frame the hole in the exterior wall where the vent will be terminated. If the wall
being penetrated is constructed of non-combustible material, i.e. masonry block or concrete, a hole with
zero clearance to the pipe is acceptable.
