Vent Considerations

Twist-lock procedure:
Four indentations, located on the female ends
of pipes and fittings, are designed to slide straight onto the male ends of
adjacent pipes and fittings by orienting the four pipe indentations so they
match and slide into the four entry slots on the male ends (see Figure
17) . Push the pipe sections completely together, then twist-lock one sec-
tion clockwise approximately one-quarter turn until the two sections are
fully locked . The female locking lugs will not be visible from the outside
on the pipe or fittings . They may be located by examining the inside of
the female ends .
