Installing Vent Components (Figure 46)
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.
