1.4.9 Combustion Air Filtration
If combustion air contamination from ingested particulate matter may be a
concern in any installation, an optional air intake filter may be installed. IBC
supplied air intake filters have a known pressure drop and fouling factor and
should be used as a component of the combustion air system according to the
allowable intake length in Table 4.

also be used on indoor air applications as required)
1.4.10 Closet Installations
For installations in a confined space (such as a closet), ventilation openings may
be needed through a door or wall to prevent excessive heat from building up
inside the space.
The boiler shall not be exposed to ambient conditions above 122°F (50°C) or
below 32°F (0°C).
