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.

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.
