3.- The air piping must terminate in a down-turned
elbow as shown in Figures 11-15 and 11-16. This
arrangement avoids recirculation of flue products
into the combustion air stream;
4.- The vent piping must terminate in an elbow
pointed outward or away from the air inlet, as
shown in Figures 11-15 and 11-16;
WARNING!!!
Do not exceed the
maximum lengths of the outside vent piping
shown in Figures 11-15 and 11-16. Excessive
length exposed to the outside could cause
freezing of condensate in the vent pipe,
resulting in potential appliance shutdown.
5.- Maintain clearances as shown in Figures 11-15
and 11-16. 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;
c. Do not terminate closer than 6 feet horizontally
from any electric meter, gas meter, regulator,
relief valve, or other equipment. Never
terminate above or below any of these within 6
feet 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.
