CLEARANCE
D. 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 
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 5.3) requires only enough 
support to maintain the necessary 
clearance to combustibles. However, 
the vent attachment point and the 
fi restop location are considered to be 
supports.
