F. Use of Flex Vent (SLP-FLEX
Series 6-5/8 Inch)
TERMINATION
CAP
The flex vent must be supported with the
3 in. CLEARANCE
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
FLEX-VENT
clearance to combustibles. A simple "up
and out" installation (Figure 4.9) requires
only enough support to maintain the neces-
1 in.
sary clearance to combustibles. However,
CLEARANCE
the vent attachment point and the firestop
location are considered to be supports.
