3 INSTALLATION INSTRUCTIONS
The boiler must be installed by personnel authorised by the Ministry of Industry, in compliance with
the applicable laws and regulations.
This boiler is suitable for heating water to a temperature below boiling point at atmospheric pressure.
It must be connected to a heating buffer tank, which must always be compatible with its performance
and power.
This appliance must only be used for the purpose for which it has been expressly designed. Any other
use is considered unsuitable and therefore hazardous. The manufacturer shall not be considered liable
under any circumstances for damage caused by unsuitable, erroneous or irrational use.
Remove all the packaging and check the contents are complete. In case of doubt, do not use the
boiler. Contact your supplier. Keep the packaging elements out of reach of children, as they can be
dangerous.
When you no longer wish to use the boiler, disable the parts that could represent a potential hazard.
3.1 Location
The boiler must be installed in a sufficiently ventilated site, away from humidity. It must be located
so that the air grilles on the premises are not obstructed and normal boiler maintenance is possible.
It must be kept a minimum distance of 1 m from the fuel tank or install a radiation protection plate.
The boilers must not operate on flammable surfaces. The boiler must have an external combustion
air supply (minimum opening 300 cm
2 ).
Generally, it is not recommended to install boilers of up to 50 kW in stairways, living areas, corridors
or garages. Similarly, installing boilers in locations with ventilation, fans, extractor fans, air
extraction systems, etc. should be avoided (e.g. tumble dryer extraction). It must be kept a
minimum distance of 0.4 m from flammable building materials so as to not reach surfaces
temperatures above 85°C.
3.2 Hydraulic installation
The hydraulic installation must be made by qualified personnel. The applicable installation
legislation (RITE) must be complied with, and the following recommendations should also be taken
into account:
- It is obligatory and essential to install a heating water buffer tank (see
“
Example of
installation with buffer tank
”
).
The minimum volume of the buffer tank must be calculated
based on Standard EN 303-5.
- It is obligatory and essential to install a device for raising the return temperature , to prevent
any water condensation in the heat exchanger. If this requirement is not complied with,
DOMUSA TEKNIK 's guarantee of the appliance will automatically be null and void.
- It is obligatory and essential to install the temperature relief valve supplied with the boiler.
To correctly install the boiler, carefully follow the instructions given in the section "Installing
the temperature relief valve" . If this requirement is not complied with,
DOMUSA TEKNIK 's
guarantee of the appliance will automatically be null and void.
- The inside of the installation piping should be thoroughly cleaned before switching on the
boiler.
- We recommend inserting cut-off valves between the installation piping and the boiler to
simplify maintenance tasks.
