2.8.3

Combustion air supply conditions

Operating conditions
Air intake flow cross-section for
combustion air drawn from
outside (divided between max. 2
apertures)
Table 6 Observe national regulations for boilers which draw their air supply from the boiler room.
If the burner is to be operated with sealed combustion by drawing its
combustion air solely from the outdoors, follow burner manufacturer's
specification.


Excessive dust inside the boiler room must be avoided when the boiler is operating,
Combustion air supplied from outside must not be excessively loaded with dust or
•Air supply contaminated with dust from production and processing facilities, e. g.

The combustion air must be free from halogenated-hydrocarbon compounds.
•Identify the source of halogen-hydrocarbon compounds and seal it off. Where this is
impossible, route combustion air from areas that are not contaminated by halogen-

During burner operation, no mechanical air handling equipment may be operated that

Prevent small animals from entering the boiler room, particularly through the air inlet vents

Maintain clearances between the boiler and flammable materials in accordance with local
regulations. A minimum clearance of 16" is required. Never store flammable materials or

In case of an acute risk of flooding, disconnect the boiler in time from its fuel and power
supply before water enters the room. Any components or control equipment, which came
in contact with flood water, must be replaced before re-commissioning.
Boiler output (in case of
multi-boiler systems = total output)
< 170,000 Btu/hr


This boiler can be operated with #2 Fuel Oil ASTM D396-05 Type 2. Select a burner that is
suitable for this fuel typ.

Free of contaminants (for example dust, mist, humidity), i. e. a constant operation will not
lead to accumulation of deposits, in valves, strainers and filters and could lead to service
calls.
Notes – Requirement in greater detail
