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

For vent configurations requiring more than one 45º and 90° elbow the following formulas apply:

Formula 1: HT < 4.2 VT

Formula 2: HT + VT < 24.75 feet

Since both formulas are met, this vent configuration is acceptable.
