The location of the vent terminal depends on the following minimum clearances and considerations (see diagram at left):

Minimum twelve (12) inches (30 cm) above roof.2

Minimum twelve (12) inches (30 cm) above anticipated snow level.

Maximum twenty-four (24) inches (60 cm) above roof level without additional support for vent.

Four (4) feet (1.2 m) from any gable, dormer or other roof structure with building interior access (i.e., vent, window, etc.).

Ten (10) feet (3 m) from any forced air inlet to the building. Any fresh or make-up air inlet such as a dryer or furnace area is considered to be a forced air inlet.3
