5.1 Safety information
Caution!
Sharp edges pose a cutting hazard.
Handle the cladding parts with care and avoid contact with sharp edges.
5.2 Boiler room requirements
The boiler room must satisfy the applicable local building regulations.
The boiler room ventilation must satisfy the applicable local regulations in this regard.
Boilers may not be installed in rooms containing halogen compounds which can be carried
into the combustion air (e.g. wash rooms, drying rooms, DIY rooms, hair dresser rooms).
Halogen compounds can originate, for example, from cleaning and degreasing agents,
solvents, glue, and bleaching lyes.
Ensure that the required combustion air can flow unhindered at all times.
This is important for the correct operation of all the boilers installed therein and to protect the
users from an oxygen depleted atmosphere.
An adequate fresh air supply meeting the local regulations must be provided.
5.2.1 Room air dependent installation
The applicable regulations do not normally provide any specific data on the size of air intakes.
They only require the pressure in the boiler room not to be below 3 N/m
2
.
This means that for a rated thermal output of up to 50 kW an air intake with a cross section of
at least 300 cm
2
must be available.
For rectangular apertures the aspect ratio should not exceed 1.5:1. If a grid is fitted on the air
intake, a suitable allowance must be made to obtain an air intake cross section of 300 cm
2
.
If the combustion air is aspirated from within
the boiler room, it is possible to remove the
air intake hose (1) to reduce suction noise.
5.2.2 Room sealed installation
Configuration based on a concentric flue system:
The suction air is supplied through a double-wall flue
system.
Ensure the boiler room is sufficiently ventilated.
