See graph to determine the required vertical rise V T for the<br />
required horizontal run H T .<br />
HORIZONTAL VENT RUN PLUS OFFSET IN FEET H T<br />
The shaded area within the lines represents acceptable<br />
values for H T and V T .<br />
For vent configurations requiring more than one 90° elbow,<br />
the following formulas apply:<br />
Formula 1: H < V T T<br />
Formula 2: H + V < 40 feet<br />

Example 3:<br />
V1 = 3 ft<br />
V2 = 8 ft<br />
VT = V + V = 3 + 8 = 11 ft<br />

H1 = 2.5 ft<br />
H2 = 2 ft<br />
HR = H + H = 2.5 + 2 = 4.5 ft<br />

HO = .03(three 90° elbows - 90°) = .03(270° - 90°) = 5.4 ft<br />
HT = H + H = 4.5 + 5.4 = 9.9 ft<br />

Since both formulas are met, this vent configuration is acceptable.<br />
