2.13 COMBUSTION AIR
The
Benchmark Venting and Combustion Air Guide
, TAG-0022 (GF-2050) MUST be consulted
before any inlet air venting is designed or installed. Air supply is a direct requirement of ANSI
223.1, NFPA-54, CSA B149.1 and local codes. These codes should be consulted before a
permanent design is determined.
The combustion air must be free of chlorine, halogenated hydrocarbons, other chemicals that
can become hazardous when used in gas-fired equipment and other combustion products.
Common sources of these compounds are swimming pools, degreasing compounds, plastic
processing, and refrigerants. Whenever the environment contains these types of chemicals,
combustion air MUST be supplied from a clean area outdoors for the protection and longevity of
the equipment and warranty validation.
If combustion air is supplied directly to the unit(s) though air duct(s), see section 2.13.1 below.
If combustion air is not supplied through air ducts, it must be supplied to the unit(s) through two
permanent openings. These two openings must have a free area of
not less than one square
inch (6.5 cm
2
) for each 4000 BTUs (1.17 kW) input
for each unit
. The free area must take
into account restrictions such as louvers and bird screens.
For Canada installations, refer to the requirements specified in CSA B149.1-10, sections 8.4.1
and 8.4.3.
