NOTICE PVC/CPVC or ABS is acceptable air inlet pipe material.

5.Maintain clearances as shown in FIG.’s 4-1A thru 4-4B, pages 23 thru 25. Also maintain the following:

a.Vent must terminate:

•At least 6 feet (1.8 m) from adjacent walls.

•No closer than 12 inches (305 mm) below roof overhang.

•At least 7 feet (2.1 m) above any public walkway.

•At least 3 feet (.9 m) above any forced air intake within 10 feet (3 m).

•No closer than 12 inches (305 mm) below or horizontally from any door or window or any other gravity air inlet.

b.Air inlet must terminate at least 12 inches (305 mm) above grade or snow line; at least 12 inches (305 mm) below the vent termination (FIG. 4-1B); and the vent pipe must not extend more than 24 inches (610 mm) vertically outside the building.

c.Do not terminate closer than 4 feet (1.2 m) horizontally from any electric meter, gas meter, regulator, relief valve, or other equipment. Never terminate above or below any of these within 4 feet (1.2 m) horizontally.

6.Locate terminations so they are not likely to be damaged by foreign objects, such as stones or balls, or subject to buildup of leaves or sediment.
