Closet Installations - IBC VFC 15-150 Installation And Operating Instructions Manual

NOTE
Combustion fan
blockages can occur when
environmental particulate and
foreign matter contaminants
(leaves, dust, dandelion &
cottonwood fluff, etc) are
drawn into the air intake. In
areas where this problem is
suspected to be an issue,
our optional air intake filter
should be installed.
Filters should be checked
and cleaned or replaced on
a regular schedule based on
the severity of the problem.

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.

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).
