Installing Vent Components (Figure 28)
Begin the vent system installation by installing the first 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 or silicone sealant rated above 300°F/149°C.
The inner flue joints do not require any sealant.
All 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.
