walkways where condensate could drip
and/or freeze and create a nuisance or hazard.
h. When adjacent to a public walkway, locate
exit terminal at least 7 feet above grade.
i.
Do not locate the exit termination directly
under roof overhangs to prevent icicles
from forming.
j.
Provide 3 feet clearance from the inside cor-
ner of adjacent walls.
2. Determine air intake pipe location.
a. Provide 1 foot clearance from the bottom of
the air inlet pipe and the level of maximum
snow accumulation. Snow removal may be
necessary to maintain clearances.
b. Do not locate air intake pipe in a parking area
where machinery may damage the pipe.
c. When venting with a two pipe system, max-
imum distance between air intake and
exhaust vent is 6 feet (1.8 m). Minimum dis-
tance between exhaust vent and air intake
on single boiler is 8" (0.2 m) center-to-cen-
ter. Minimum distance between vents and
intakes on multiple boilers is 8" (0.2 m) cen-
ter-to-center. See Figure 4.2.
