2.8.2
Conditions for the boiler room and the environment
2.8.3
Combustion air supply conditions
If the burner is to be operated with sealed combustion by drawing its
combustion air solely from the outdoors, follow burner manufacturer's
specification.
2.8.4
Conditions, Fuel
Operating conditions
Notes – Requirement in greater detail
Temperature in the boiler room
+40 to +104 °F
relative humidity
max. 90 %
No condensation or precipitation inside the boiler room
Dust/airborne particles
Excessive dust inside the boiler room must be avoided when the boiler is operating,
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.
quarries, mines, etc.
•Airborne particles from thistles and similar
Halogenated-hydrocarbon
compounds
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.
Fans that extract air from the
boiler room.
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
Small animals
Prevent small animals from entering the boiler room, particularly through the air inlet vents
– by fitting them with screens.
Fire safety
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.
Flooding
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.
Table 5 Boiler room and ambient conditions
Operating conditions
Boiler output (in case of
multi-boiler systems = total output)
Ventilation air cross-section in square inches
(unrestricted aperture)
Air intake flow cross-section for
combustion air drawn from
outside (divided between max. 2
apertures)
< 170,000 Btu/hr
At least 23.25 square inches
Table 6 Observe national regulations for boilers which draw their air supply from the boiler room.
Operating conditions
Notes – Requirement in greater detail
Permissible fuels for boilers
without integral burners
This boiler can be operated with #2 Fuel Oil ASTM D396-05 Type 2. Select a burner that is
suitable for this fuel typ.
Contamination
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.
