1.4 Regulations, official approvals
For installation and operation of the system, the following
regulations are to be observed:
Germany
• DIN EN 12831 Heating systems in buildings – proce-
dure for calculating the standard heating load.
• DIN EN 12828 Heating systems in buildings - planning
of hot water systems.
• DIN EN 13384 Exhaust gas systems – thermal and uid
dynamic calculation methods.
• DIN 4755 Oil-red systems: design, construction and
technical safety requirements.
• DIN 4756 Gas-red systems: design, construction and
technical safety requirements, planning and execution
(for operation with gas burners).
• DIN 18160 House chimneys, requirements, planning
and execution.
• PED (Pressure Equipment Directive).
• TRD 721 Safety equipment to safeguard against ex-
cess pressures / safety valves / for group II steam boil-
ers.
• VDI 2035 Prevention of damage by corrosion and the
formation of scale in hot water systems.
• DIN 57 116 / VDI 0116 Electrical equipment for ring
systems (VDE regulation).
Austria
• ÖNorm (Austrian standard) B 8130 Open hot water sys-
tems, safety installations.
• ÖNorm B 8131 Closed-circuit hot water systems, safe-
ty, construction and testing regulations.
• ÖNorm B 8133 Water heating systems, technical safety
requirements.
• ÖNorm B 8136 Heating systems, space requirements
and other building requirements.
• ÖNorm EN 12831 Heating installations in buildings –
procedure for calculating the standard heating load.
• ÖNorm EN 12828 Heating systems in buildings: plan-
ning of hot water heating systems.
• ÖNorm EN 13384 Exhaust gas systems – procedure
for heat and technical gasow calculations.
• ÖNorm M 7515 Calculation of chimney dimensions;
denition of expressions, calculation procedures.
• ÖNorm H 5171 Heating systems – technical building
requirements.
• ÖVGW TR gas.
Switzerland
• VKF-Association of Cantonal Fire Insurers.
• Regulations of the re police.
• SN (Swiss standard) EN 12831 Heating installations in
buildings – procedure for calculating the standard heat-
ing load.
• SN EN 12828 Heating systems in buildings - planning
of hot water heating systems.
• SN EN 13384 Exhaust gas systems - procedure for
heat and technical gasow calculations.
• SVGW Swiss Gas and Water Federation.
• SNV 27 10 20 Aeration and ventilation of the boiler room.
• SWKI 97-1 Water treatment for heating, steam and air-
conditioning plant.
• SWKI 80-2 Technical safety regulations for heating in-
stallations.
• KRW Corrosion caused by halides.
• KRW/VSO/FKR Electrical connections on heating boil-
ers and burners ready to plug in.
• Technical tank regulations TTV 1990.
and further prescriptions and standards published by
CEN, CEN ELEC, DIN, VDE, DVGW, TRD and the leg-
islature.
In a similar manner, the regulations of the local building
authorities, insurers and chimney inspectors must be tak-
en into account. When gas is used as fuel, the regulations
of the responsible gasworks must be observed and an
ocial authorisation may also be required.
1.5 Guarantee
Trouble-free functionality is only guaranteed when both
these and the operating instructions are meticulously ob-
served and the boiler is regularly serviced by a qualied
engineer (maintenance contract). Repair of faults and
damage caused by contaminated operating materials
(gas, water, combustion air), unsuitable chemical addi-
tives in the heating water, careless treatment, faulty in-
stallation, unauthorised modications and damage as a
result of force are not subject to our guarantee liability;
this applies also to corrosion caused by halides, e.g. em-
anating from spray canisters, paints and varnishes, adhe-
sives, solvents and cleaning agents.
