Flex Vent
The flex vent must be supported with the spacing between
support intervals not exceeding 4 feet, with no more than ½
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 9) requires only enough support to main-
tain the necessary clearance to combustibles. However, the
vent attachment point and the firestop location are consid-
ered to be supports.
