E. Use of Flex Vent
The fl ex vent must be supported with the spacing between
TERMINATION CAP
support intervals not exceeding 4 feet, with no more than
3 in. CLEARANCE
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 (Figure 7.3) requires only enough sup-
FLEX VENT
port to maintain the necessary clearance to combustibles.
However, the vent attachment point and the fi restop loca-
1 in. CLEARANCE
tion are considered to be supports.
