4. INSTALLATION GUIDE
4.1. 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.
CAUTION:
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.
4.2. Planning dimensions
4.2.1. Space required
It must be possible to open the furnace door, including
burner, by 90°.
E = Burner length
A = E + d + 150 mm

4.2.2. 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, no base is needed for the boiler series.
