▪ Damage due to impurities in combustion air.
Do not use any solvents or cleaning agents containing chlorine and hydrogen
halides in the room where the boiler is installed (e.g. chlorination units for
swimming pools).
▪
Keep the air suction opening of the boiler free of dust.
▪ The system must be protected against the chewing or nesting of animals (e.g.
rodents etc.).
Ventilation of the boiler room
Ventilation air for the boiler room should be taken from and expelled directly outside,
and the openings and air ducts should be designed to prevent weather conditions
(foliage, snowdrifts, etc.) from obstructing the air flow.
Unless otherwise specified in the applicable building regulations for the boiler room,
the following standards apply to the design and dimensions of the air ducts:
ÖNORM H 5170 - Construction and fire protection requirements
TRVB H118 - Technical directives on fire protection/prevention
2.4.4 Requirements for central heating water
Unless contrary to other national regulations, the latest versions of the following
standards and guidelines apply:
Austria:
Germany:
ÖNORM H 5195
VDI 2035
Switzerland
:
Italy:
SWKI BT 102-01
UNI 8065
Observe the standards and also follow the recommendations below:
❒
Aim for a pH value of between 8.2 and 10.0. If the central heating water comes
into contact with aluminium, the pH value must be between 8.0 and 8.5
❒ Use prepared water which complies with the standards cited above for filling and
makeup water
❒ Avoid leaks and use a closed heating system to maintain water quality during
operation
❒ When filling with make-up water, always bleed the filling hose before connecting,
in order to prevent air from entering the system
Advantages of prepared water:
▪ Complies with the applicable standards
▪ Less of a drop in output due to reduced limescale build-up
▪ Less corrosion due to fewer aggressive substances
▪ Long-term cost savings thanks to improved energy efficiency
