See graph to determine the required vertical rise VT for the required horizontal run HT.

HORIZONTAL VENT RUN PLUS OFFSET IN FEET HT

The shaded area within the lines represents acceptable values for HT and VT .

For vent configurations requiring elbows, the following for- mulas apply:

Formula 1: HT < VT

Formula 2: HT + VT < 40 feet

V1

=5 ft

V2

=10 ft

VT

= V1 + V2 = 5 + 10 = 15 ft

H1

=1 ft

H2

=3 ft

H3

=2.5 ft

HR

= H1 + H2 + H3 = 1 + 3 + 2.5 = 6.5 ft

HO

= .03(four 90° elbows - 90°)

 

= .03(90 + 90 + 90 + 90 - 90) = 8.1 ft

HT

= HR + HO = 6.5 + 8.1 = 14.6 ft

HT + VT = 14.6 + 15 = 29.6 ft

Formula 1: HT < VT 14.6 < 15

Formula 2: HT + VT < 40 feet

29.6 < 40

Since both formulas are met, this vent configuration is ac- ceptable.
