nstalling Vent Components (Figure 36)
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.
