4. For installations using a round support box/wall thimble
(check pipe manufacturer's instructions), mark the wall
for a 10 in. x 10 in. (254 mm x 254 mm) 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. (178 mm) diameter hole is
acceptable.

• Ensure vent components are locked
together correctly.
• Pipe may separate if not properly joined.
WARNING
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 specifi ed slope (if required).
Improper support may allow vent to sag or separate.
WARNING
FEMALE LOCKING LUGS
MALE LOCKING
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 being planned. If this
is the case, you may want to adjust the location of the
appliance.
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.
3. 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.
