Use Of Flex Vent - Heat & Glo SLR-D Owner's Manual

F. Use of Flex Vent
The flex 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 direc-
tion, and in any location where it is necessary to maintain
the necessary clearance to combustibles. A simple "up
and out" installation (Figure 7.17) requires only enough
support to maintain the necessary clearance to combusti-
bles. However, the vent attachment point and the firestop
location are considered to be supports.
