Flex Vent
The fl ex 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 requires only enough support to maintain
the necessary clearance to combustibles. However, the
vent attachment point and the fi restop location are con-
sidered to be supports.
