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
commissioning of the boiler with the
standard boiler controller. When an
additional system 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 pres-
sure 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
volumes, it's necessary to respect the
maximum filling and additional volumes
with corresponding hardness values as
stated in the german VDI2035
standard. In the table you can find the
nominal values for filling and additional
water for the R600 according to the the
VDI2035.
The table at the left gives an indication
of the relation between the water
quality and the maximum water filling
volume 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
connected 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.
