Commissioning
Water and hydraulic system
Commissioning of the boiler should be
carried out by authorized personnel
only. Failure to respect this condition
makes the guarantee void. A protocol
of the commissioning should be filled
out (see end of this chapter for example
of commissioning protocol).

This chapter explains the commissio-
ning of the boiler with the standard boi-
ler controller. When an additional sys-
tem controller is installed, please refer
to its manual for commissioning the
controller.

Water pressure
Open the valves to the system. Check
the water pressure in the system. If the
water pressure is too low (see table
below), increase the pressure up to at
least the minimum required water
pressure in the table.
Filling can be done via the fill and drain
valve (2) on the return connection (1) of
the boiler.

Water quality
The system should be filled with water
with a PH value between 8,0 and 9,5.
The chloride value of the water should
not exceed 50 mg/l. Entry of oxygene
by diffusion should be prevented at all
times. Damage to the heat exchanger
because of oxygene diffusion will not
be taken under warranty.
In installations with higher water volu-
mes, it's necessary to respect the maxi-
mum filling and additional volumes with
corresponding hardness values as sta-
ted in the german VDI2035 standard. In
the table you can find the nominal va-
lues for filling and additional water for
the R3400/R3500/R3600 according to
the the VDI2035.
The table at the left gives an indication
of the relation between the water quali-
ty and the maximum water filling volu-
me during the lifetime of the boiler.
Consult the original text of the VDI2035
for more detailed information.
Hydraulic system
Check if the boiler is hydraulically con-
nected to the system in such way, that
water flow can be secured at all times
during burner operation. The water flow
is supervised by the water flow switch
in the boiler and a lack of flow will lead
to a direct burner stop and lockout of
the boiler.
