Installing Vent Components (Figure 29)
Begin the vent system installation by installing the first Simpson
Duravent component, 90° elbow to the starting collars or straight
pipe on the top of the appliance, then the straight pipe length and
then horizontal or vertical termination kit.
NOTE: All outer connection joints must be sealed with aluminum
tape, screws or silicone sealant rated above 300°F/149°C. The
inner flue joints do not require any sealant.
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
configuration. Be certain that each succeeding vent component
is securely fitted and locked into the preceding component in the
vent system.
