Notes – detailed requirements
+5 to +40 °C
max. 90 % No dew formation or precipitation inside the boiler room
– 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 seed; air filters should be fitted where required to prevent
this:
– Air supply loaded with dust from dirt roads and paths.
– Air supply loaded with dust from production and processing facilities, e.g.
quarries, mines, etc.
– Airborne seed from composite blossom
– The combustion air must be free from halogenated hydrocarbon
compounds.
– Identify the source of halogenated hydrocarbon compounds and prevent
their ingress. Where this is impossible, route combustion air from areas that
are not contaminated by halogenated hydrocarbon compounds.
Observe the following:
– Buderus Catalogue - Heating Technology Germany
– Code of Practice K3 in the Buderus catalogue
– During burner operation, no mechanical air handling equipment may be
operated which could extract combustion air from the boiler room, e.g.:
– Cooker hood
– Dryer
– Ventilation equipment
– Protect the boiler room and particularly the combustion air inlet against the
ingress of small animals, for example by means of a grille.
– Maintain clearances between the boiler and flammable materials in accordance
with local regulations. Generally, maintain a minimum clearance of 40 cm. Never
store flammable materials or liquids in the vicinity of the boiler.
– In case of an acute risk of flooding, disconnect the boiler in good time from its
fuel and power supply before water enters the room. Any general and burner
components or control equipment which comes into contact with water must be
replaced before re-commissioning.
