No dew formation or precipitation inside the boiler room
dust/airborne seeds
–
–
Excessive dust must be prevented inside the boiler room,
when the boiler is operating, e.g.:
!
building dust through very dusty building measures
The inrushing combustion air must not be excessively
dusty, e.g:
!
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.
Combustion air supplied from outside must not be
excessively loaded with airborne seeds, which should be
prevented, where required, by air filters, e.g.
!
airborne seed from composite blossom
halogenated hydrocarbon
compounds
–
–
The combustion air must be free from halogenated
hydrocarbon compounds.
!
Identify the source of halogenated hydrocarbon compounds
and eliminate their ingress. Where this is impossible, route
combustion air from areas which are not contaminated by
halogenated hydrocarbon compounds.
Observe the following:
–
Buderus Catalogue Heating Technology Germany
–
Code of Practice K 3 (Information Sheet No. 1 of the Federal
Association of the Germany Heating Industry)
fans, which extract air from the
boiler room.
–
–
During burner operation, no mechanical air handling equipment
may be operated, which would extract combustion air from the
boiler room, e.g.:
!
cooker hood
!
dryer
!
ventilation equipment
small animals
–
–
Protect the boiler room and particularly the combustion air inlet
against ingress of small animals, e.g. by means of a grille.
fire protection
–
–
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.
flooding
–
–
In case of an acute risk of flooding, disconnect the gas-fired
boiler from its power supply and shut off the gas supply before
water enters the boiler room. Any valves and control equipment
which comes into contact with water, must be replaced before re-
commissioning.
