Measuring Standards - Heat & Glo TRUE-36S-IFT 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 information
on effective length of pipe components.
• Horizontal terminations are measured to the outside
mounting surface (fl ange of termination cap) (see Figure
4.6).
• Vertical terminations are measured to top of last section
of pipe. See Figure 4.7.
• Horizontal pipe installed level with no rise.
