Venting Arrangement for Vertical Terminations - 5" x 8" (127 mm x 203 mm) Rigid and Flex Pipe
The shaded area in the diagram shows all allowable combinations
of straight vertical and offset-to-vertical terminations, using two
90
o
elbows with rigid/flex pipe venting systems.
• Two 45
o
elbows equal to one 90
o
elbow.
• Vent must be supported at offsets.
• Minimum distance between elbows is 1 ft. (305 mm).
• Maintain clearances to combustibles as listed in the
"Clearances" section.
• Horizontal vent must be supported every 3 feet (0.9 m).
• Firestops are required at each floor level and whenever
passing through a wall.
• Must use optional rigid pipe adaptor (Part# 770-994) when
using rigid pipe vent systems.
• Refer to the "Vent Restrictor Position" section for details on
how to change the vent restrictor from the factory setting

For vertical terminations, the Regency Direct Vent Flex System
may be used for installations with a maximum vent length of
up to 40 feet including offsets. If longer runs are required, rigid
pipe must be used. If no offsets are used, the maximum run is
per the chart on this page.
