A. VENT SYSTEM INSTALLATION
1. Determine vent terminal location:
a. Vent length must be between 3' and 20' long.
See paragraph 3 and Figure 4.1 for air intake
requirements.
b. No clearance is required between vent terminal
and combustible construction.
c. Vent terminal extends 12" beyond outside wall
surface and at least 16" beyond inside wall
surface. See Figure 4.1.
d. Provide 3' clearance above any forced air inlet
within 10'.
e. Provide 4' clearance below, 4' beside, or 1' above
any door, window, or gravity air inlet into any
building.
f.
On multiple boiler installations, provide 18"
clearance between vent terminals. Located
terminals on same horizontal plane.
g. Provide 1' clearance between bottom of vent
terminal and ground level or between bottom of
vent terminal and normal snow lines.
h. Provide 4' horizontal clearance from, and in no
case above or below, unless a 4' horizontal
clearance is maintained, from electric meters, gas
meters, gas regulators, and gas relief equipment.
i.
Provide 5' clearance to the vent outlet of a fuel
oil supply tank.
j.
Provide 1' clearance to the soffit of the roof and
3' clearance to an inside corner of an L-shaped
building.
k. Do not locate vent terminal over public walkways
where condensate could create a nuisance or
hazard.
l.
When adjacent to a public walkway, locate vent
terminal at least 7' above grade.
