Step 1.
Determine the desired location of the appliance. Check to
ensure that wall studs or roof rafters are not in the way when
the venting system is attached. If this is the case, you may
want to adjust the location of the appliance.
Figure 5.4
Step 2.
Direct vent pipe is designed with a locking connection. To
connect the venting system to the appliance flue outlet, a
twist-lock adapter is built into the appliance at the factory.
Wall thickness may vary. Remember to include wall
thickness in minimum clearances when figuring venting
lengths for your installation needs.
Note
: Female ends of direct vent pipe/elbows are designed
to slide straight onto the male ends of adjacent pipes by
orienting the pipe indentations so they match and slide into
the entry slots on the male ends, see
Figure 5.4
. Push
the pipe sections completely together, then twist-lock one
section clockwise approximately one-quarter turn, until the
two sections are fully locked. The female locking lugs may
not be visible from the outside. They may be located by
examining the inside of the female ends.
Fire Risk.
Explosion Risk.
Combustion Fume Risk.
Use vent run supports per installation instructions.
Connect vent sections per installation instructions.
• Maintain all clearances to combustibles.
• Do NOT allow vent to sag below connection
point to appliance.
• Maintain specified slope (if required).
WARNING
Improper support may allow vent to sag or separate.
Fire Hazard.
Exhaust Fume Risk.
Impaired Performance of Appliance.
WARNING
• Ensure vent components are locked together correctly.
• Pipe may separate if not properly joined.
Step 3.
For installations using a round support box/wall thimble
(check pipe manufacturer's instructions), mark the wall for a
10 in. x 10 in. (254mm x 254mm) square hole. The center
of the square hole should line up with the center line of the
horizontal pipe, as shown in
Figure 5.5
. Cut and frame the
hole in the exterior wall where the vent will be terminated. If
the wall being penetrated is constructed of noncombustible
material, i.e. masonry block or concrete, a 7 in. (178mm)
diameter hole is acceptable.
