CLEARANCE
FLEX VENT
F. Use of Flex Vent
The
fl
ex 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 (Fig-
ure 4.6) requires only enough support
to maintain the necessary clearance
to combustibles. However, the vent at-
tachment point and the
fi
restop loca-
tion are considered to be supports.
