Use Of Flex Vent (Slp-Flex Series 6-5/8 Inch); Vent Diagrams - Majestic JADE32IN Installation Manual

F. Use of Flex Vent (SLP-FLEX Series 6-5/8
Inch)
The flex vent must be supported with the spacing between
support intervals not exceeding 4 feet, with no more than
1/2 inch sag between supports.
A support is required at each change in venting direction,
and in any location where it is necessary to maintain the
necessary clearance to combustibles. A simple "up and
out" installation (Figure 4.8) requires only enough support
to maintain the necessary clearance to combustibles.
However, the vent attachment point and the firestop loca-
tion are considered to be supports.
