Colinear Direct Vent - Pitched Roof Installation

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 specifications are summarized in Figure 30.

Figure 31

In both vertical and horizontal colinear direct vent applications, a colinear transition plate model PVCT 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 (model #PVVTC), PTrap, or two 90º elbows. When transi- tion plate (model PVCT) is used, two termination caps (model PVVTC) may NOT be used.

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.
