5.Maintain clearances as shown in FIG.’s 4-1A thru 4-3B, pages 22 - 24. Also maintain the following:

a.Vent must terminate:

•At least 6 feet from adjacent walls.

•No closer than 12 inches below roof overhang.

•At least 7 feet above any public walkway.

•At least 3 feet above any forced air intake within 10 feet.

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

b.Air inlet must terminate at least 12 inches above grade or snow line; at least 12 inches below the vent termination; and the vent pipe must not extend more than 24 inches vertically outside the building as shown in FIG. 4-1B. Condensate could freeze and block vent pipe.

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