3.2 Installation and approval of the heating system

The boiler should be operated in a closed heating system. The following standards

govern the installation:

EN 12828 - Heating Systems in Buildings

NOTICE! Each heating system must be officially approved.

The appropriate supervisory authority (inspection agency) must always be informed

when installing or modifying a heating system, and authorisation must be obtained

from the building authorities:

Austria: report to the construction authorities of the community or magistrate

Germany: report new installations to an approved chimney sweep / the building

authorities.

3.3 General information for installation room (boiler room)

Boiler room characteristics

▪ The floor must be even, clean and dry and have an adequate load-bearing

capacity.

▪ There must not be a potentially explosive atmosphere in the boiler room as the

boiler is not suitable for use in potentially explosive environments.

▪ The boiler room must be frost-free.

▪ The boiler does not provide any light, so the customer must ensure sufficient

lighting in the boiler room in accordance with national workplace design

regulations.

▪ When using the boiler above 2000 metres above sea level you should consult the

manufacturer.

▪ Danger of fire due to flammable materials.

The floor of the boiler room must not be flammable. No flammable materials

should be stored near the boiler. Flammable objects (e.g. clothing) must not be put

on the boiler to dry.

▪ 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

3.4 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

make-up 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
