WARNING
CAUTION
ALL vent confi guration specifi cations MUST be followed.

Diagonal runs have both vertical and horizontal vent as-
pects when calculating the effects. Use the rise for the
vertical aspect and the run for the horizontal aspect (see
Figure 5.1).
Two 45 0 elbows may be used in place of one 90 0 elbow. On
45 0 runs, one foot of diagonal is equal to 8.5 inches hori-
zontal run and 8.5 inches vertical run. A length of straight
pipe is allowed between two 45
0 elbows (see Figure 5.1).

C. Measuring Standards
Vertical and horizontal measurements listed in the vent
diagrams were made using the following standards.
1. Pipe measurements are shown using the effective length
of pipe (see Figure 5.2).
2. Measurements are made from the appliance outer wrap,
not from the standoffs.
3. Horizontal terminations are measured to the outside
mounting surface (fl ange of termination cap) (see Figure
4.1).
4. Vertical terminations are measured to bottom of termina-
tion cap.
5. Horizontal pipe installed level with no rise.
