6. Installation guide
6.1. Boiler room and boiler room ventilation
The boiler room must be arranged in compliance with local regulations and installation specifications. Particular
attention should be paid to the ventilation of the boiler room.
Supply of combustion air must be guaranteed (non-shut opening).
Minimum air requirement is 1.6 m
3
/h for each kW of boiler power.
Minimum free section of combustion air opening is 6 cm
2
for each kW of boiler power.
Important: The combustion air must not have high dust concentrations.
Furthermore, it must be free of halogens (chlorine and fluorine compounds). An excessive presence of
halogen in the combustion air leads to great corrosion damage. The maximum permitted amount of
halogen in the combustion air is 5 ppm.
Halogen compounds are found in spray cans, thinners, cleaning agents, degreasing agents and
solvents, among others. In addition, halogen emissions are strongly suspected in the vicinity of dry
cleaners', hair dressing salons, swimming pools, printing offices and washing machines installed in the
same room.
In the case of doubt, the perfect quality of the combustion air must be ensured with an external air
intake. Make sure that there is a minimum loss of pressure, since this could impair the performance of
the burner.
6.2. Planning dimensions
6.2.1. Space required
D
T
C
A
It should be possible to open the furnace
door, including burner, by 90°.
At least 200 mm of free space should be
provided to the right and to the left of the
boiler to install boiler casing.
B
After installing the casing, the boiler can be
moved closer to the wall, but at least 60 mm
away from it.
C
The boiler cleaning hole behind the boiler
must be easily accessible and should be
600 mm away from the wall.
6.2.2. Boiler base
If the floor of the boiler room is moist or loose, a sufficiently high boiler base must be provided. Moisture does not
go well with electrical equipment!
A base is also a good idea if the height is not sufficient for installing the burner. Otherwise, a boiler base is not
required.
