E. UseofFlexVent
The ex vent must be supported with the
spacing between support intervals not ex-
ceeding 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 7.3) requires
only enough support to maintain the neces-
sary clearance to combustibles. However,
the vent attachment point and the restop
location are considered to be supports.
