Simpson Duravent vent system components lock into place by sliding
the concentric pipe section with four (4) equally spaced interior beads
onto the appliance collar or previously installed component end with
four (4) equally spaced indented sections. When the internal beads
of each starting outer pipe line up, rotate pipe section clockwise 90°
(approximately 3 inches). The vent pipe is now locked together.
Continue adding components per the pre-planned vent system
conguration. Be certain that each succeeding vent component
is securely tted and locked into the preceding component in the
vent system.
