E. 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 direc
-
tion, and in any location where it is necessary to maintain
the necessary clearance to combustibles. A simple “up
and out” installation (Figure 4.10) requires only enough
support to maintain the necessary clearance to combusti
-
bles. However, the vent attachment point and the firestop
location are considered to be supports.
