Determining Minimum Vent Height Above the Roof
WARNING: Major U.S. building codes specify minimum chimney and/or vent height above the rooftop. These minimum heights are
necessary in the interest of safety. These specications are summarized in Figure 37.
ROOF PITCH H (Min.)
Flat to 6/12 12” (305 mm)
6/12 to 7/12 15” (381 mm)
Over 7/12 to 8/12 18” (457 mm)
Over 8/12 to 16/12 24” (610 mm)
Over 16/12 to 21/12 36” (914 mm)
In both vertical and horizontal colinear direct vent applications, a colinear transition plate can be used to minimize clearances between
intake and exhaust pipes.
For exhaust and intake air, cap pipes with any of the following: Vertical termination cap, PTrap, or two 90º elbows. When transition
plate is used, two termination caps may NOT be used.
See Figure 31, Page 25.
Note: If transition plate (model PVCT) is used, the measurement for center to center of the pipes will be 2.5”. If the transition plate
(model PVCT) is not used, the measurement for center to center of the pipes can be 3” to 24” maximum.
Note: Exhaust must be a minimum
of 3” above air intake inlet.
