Measuring Standards; Use Of Flex Vent (Slp-Flex Series 6-5/8 Inch) - Majestic MERC32VN Installation Manual

E. Measuring Standards
Vertical and horizontal measurements listed in the vent
diagrams were made using the following standards:
• Pipe measurements are shown using the effective length
of pipe. See Section 12.A (Figure 12.1 for DVP, Figure
12.7 for SLP) for information on effective length of pipe
components.
• Horizontal terminations are measured to the outside
mounting surface (fl ange of termination cap) (see Figure
4.3).
• Vertical terminations are measured to bottom of
termination cap.
• Horizontal pipe installed level with no rise.
• Horizontal termination cap should have a 1/4 inch
downward slant to allow any moisture in cap to be
released.

F. 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
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 4.6) requires only enough sup-
port to maintain the necessary clearance to combustibles.
However, the vent attachment point and the fi restop loca-
tion are considered to be supports.
