Installing Vent Components
Begin the vent system installation by installing the rst Duravent component to the starting collar, 24 inch (60.10 cm) minimum straight
pipe on the top of the appliance, then the remaining pipe length and the 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 ue joints do not require any sealant.
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.
