Temperature in the boiler room
relative humidity
Dust/airborne particles
Halogenated-hydrocarbon com-
pounds
Fans that extract air from the
boiler room.

Flooding
Tab. 5 Boiler room and ambient conditions
2.8.3

Combustion air supply conditions

Operating conditions
Air intake flow cross-section for
combustion air drawn from out-
side (divided between max. 2
apertures)
Tab. 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.

Notes – Requirement in greater detail
+40 to +104 °F
max. 90 % No condensation or precipitation inside the boiler room
−
Excessive dust inside the boiler room must be avoided when the boiler is operat-
ing, e. g.:
– Dust from building work
Combustion air supplied from outside must not be excessively loaded with dust
or airborne particles; if necessary, air filters should be fitted in case:
– Air supply contaminated with dust from dirt roads and paths.
– Air supply contaminated with dust from production and processing facilities, e. g. quar-
ries, mines, etc.
– Airborne particles from thistles and similar
−
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-
hydrocarbon compounds.
−
During burner operation, no mechanical air handling equipment may be operated that could
extract combustion air from the boiler room, e.g.:
– Exhaust hood
– Tumble dryer
– Ventilation equipment
−
Prevent small animals from entering the boiler room, particularly through the air inlet vents –
by fitting them with screens.
−
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
liquids in the vicinity of the boiler.
−
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
Notes – Requirement in greater detail
−
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.
