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 opera-
ting, e.g.:
– dust from building work
Combustion air supplied from outside must not be excessively loaded with dust
or airborne seed; if necessary, air filters should be fitted to prevent this:
– 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
Halogenated-hydrocarbon com-
pounds
−
The combustion air must be free from halogen-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 halogenated-
hydrocarbon compounds.
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 liq-
uids in the vicinity of the boiler.
Flooding
−
In case of an acute risk of flooding, disconnect the boiler in time from the from its fuel and
power supply before water enters the room. Any general and burner components or control
equipment, which come into contact with water, must be replaced before re-commission-
ing.
