PREINSTALLATION
8.
Mechanical Combustion Air Supply
:
a. In installations where all combustion air is provided by
a mechanical air supply system, the combustion air shall
be supplied from the outdoors at the minimum rate of
0.35 ft3/min per 1000 Btu/hr (0.034 m3/min per 1000
W) of the total rated input of all appliances in the space.
b. In installations where exhaust fans are installed,
additional air shall be provided to replace the exhaust
air.
c. Each of the appliances served shall be interlocked
to the mechanical air supply to prevent main burner
operation when the mechanical air supply system is not
in operation.
d. In buildings where the combustion air is provided by the
mechanical ventilation system, the system shall provide
the specified combustion air rate in addition to the
required ventilation air.
9.
Louvers & Grills
:
a. The required size of openings for combustion,
ventilation, and dilution air shall be based on the net
free area of each opening.
i. Where the free area through a louver or grille is
known, it shall be used in calculating the opening
size required to provide the free area specified.
ii. Where the free area through a louver or grille is not
known, it shall be assumed that wooden louvers will
have 25% free area and metal louvers and grilles will
have 75% free area.
iii. Non-motorized dampers shall be fixed in the open
position.
b. Motorized dampers shall be interlocked with the
equipment so that they are proven in the full open
position prior to ignition and during operation of the
main burner.
i. The interlock shall prevent the main burner from
igniting if the damper fails to open during burner
startup.
ii. The interlock shall shut down the burner if the
damper closes during burner operation.
10.
Combustion Air Ducts
:
a. Ducts shall be constructed of galvanized steel or an
equivalent corrosion-resistant material.
b. Ducts shall terminate in an unobstructed space, allowing
free movement of combustion air to the appliances.
c. Ducts shall serve a single space.
d. Ducts shall not serve both upper and lower combustion
air openings where both such openings are used. The
separation between ducts serving upper and lower
combustion air openings shall be maintained to the
source of combustion air.
e. Ducts shall not be screened where terminating in an
attic space.
f. Horizontal upper combustion air ducts shall not slope
downward toward the source of the combustion air.
g. Combustion air intake openings located on the exterior
of buildings shall have the lowest side of the combustion
air intake opening at least 12 inches (305 mm) above
grade.
11. Refer to Section 3 of this manual, Venting & Air Inlet
Piping, for specific instructions for piping the exhaust and
combustion air.
