Measuring Standards:
Vertical and horizontal measurements listed in the vent
diagrams and clearances for termination were made
using the following standards:
• Pipe measurements are shown using the e
ff
ective length
of pipe. See Section 12.A (Figure 12.1) for information
on e
ff
ective length of pipe components.
• Horizontal terminations are measured to the outside
mounting surface (flange of termination cap)
.
See
Figure 4.8
.
• Vertical terminations are measured to top of last section
of pipe. See Figure 4.9.
• Horizontal pipe installed level with no rise.

E. Use of Flex Vent (SLP-FLEX Series 6-5/8
Inch)
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 direc-
tion, and in any location where it is necessary to maintain
the necessary clearance to combustibles. A simple “up
and out” installation (Figure 4.10) requires only enough
support to maintain the necessary clearance to combusti-
bles. However, the vent attachment point and the
fi
restop
location are considered to be supports.
