Installing Vent Components (Figure 16 and Figure 17)
Begin the vent system installation by installing the first Simpson
Duravent component, a straight pipe on the top of the appliance, or
rotate the vent elbow to the horizontal position then add horizontal
and vertical pipe lengths and then a horizontal or vertical termination
kit. Elbows can be added where necessary. See Pages 14 through
16 for venting requirements.
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 6 5/8 inch 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.
