VERTICAL EXAMPLES FOR COLINEAR DIRECT VENT
Note: Exhaust must be a minimum
of 3" above air intake inlet.
Colinear Direct Vent - Insert Installation
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 specifications are summarized in Figure 30.

Colinear Direct Vent - Pitched Roof Installation
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
transition 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.
