7. Sidewall Venting Configuration:
a. See Figure 3.3 for an illustration of clearances for
location of exit terminals of direct-vent venting systems.
• This boiler vent system shall terminate at least 3 feet
(0.9 m) above any forced air inlet located within 10
ft (3 m). Note: This does not apply to the combustion
air intake of a directvent appliance.
• Provide a minimum of 1 foot (30 cm) distance from
any door, operable window, or gravity intake into
any building.
• Provide a minimum of 1 foot (30 cm) clearance from
the bottom of the exit terminal above the expected
snow accumulation level. Snow removal may be
required to maintain clearance.
• Provide a minimum of 4 feet (1.22 m) horizontal clearance
from electrical meters, gas meters, gas regulators, and relief
equipment. In no case shall the exit terminal be above or
below the aforementioned equipment unless the 4 foot
horizontal distance is maintained.
• Do not locate the exhaust exit terminal over public
walkways where condensate could drip and create a
hazard or nuisance.
• When adjacent to public walkways, locate the exit
terminal at least 7 feet above grade.
• Do not locate the exhaust termination directly under
roof overhangs to prevent icicles from forming or
recirculation of exhaust gases from occurring.
• Provide 3 feet clearance from the inside corner of
adjacent walls.
b. Figures 3.4 through 3.7 show approved sidewall venting
configurations using the standard fittings supplied.
c. Figure 3.5 is only approved for locations in which the
outdoor temperature is above -5°F (-21°C) in accordance
with ASHRAE 90A-1980 recommendations.
