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 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
−
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.
−
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 liq-
uids in the vicinity of the boiler.
−
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.
Approved for B5 Fuel Oil (5% biodiesel (B100) according ASTM D6751)
The burner may only be operated with the specified fuel.
Clean and service once a year. Check that the entire system functions properly at the same time. Immediately rec-
tify any faults identified.
