7.2.3 Guidelines for the location of the air intake terminal
In addition to the minimum clearances of terminations
( Chapter „7.1.2.1 Location of Exhaust Wall Termina-
tion", page 23), observe the following rules:
– Both the intake and exhaust terminations must be lo-
cated on the same outside wall in order to balance
wind pressure effects.
– Wall terminations shall not be facing the direction of
prevailing winds.
– The exhaust terminal shall be at least 1 ft. above
grade and snow line, and where it is not susceptible
to blockage from debris, leaves or falling snow or ice.
– An outside air intake riser is permitted, provided it ter-
minates in 2 x 90° elbows facing down (
– The intake and exhaust terminals must be at least
4 ft. apart when using the Aerocowl (AT-4) exhaust
termination. This minimum distance can be reduced
to 2 ft. when the intake terminal is at least 1 ft. below
the exhaust terminal.
– A ½" wire-mesh screen at the exhaust terminal must
be maintained in good working order.
