I. 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 11.A for information on effective
length of pipe components.
• Horizontal terminations are measured to the outside
mounting surface (flange of termination cap) (see Figure
5.15).
• Vertical terminations are measured to top of last section
of pipe. See Figure 5.16.
• Horizontal pipe installed level with no rise.

firestop must be installed.
• When penetrating a combustible ceiling, a ceiling firestop

horizontal runs may be level.
• Horizontal termination cap should have a 1/4 inch
downward slant to allow any moisture in cap to be
