5 Commissioning the heating system
This chapter describes the commissioning of the boiler
with a control unit in the Bosch CFB controls series. The
commissioning process for the different types of control
unit is the same.
B Complete the commissioning report during
commissioning ( see Chapter 5.4, page 38).
NOTICE: Risk of boiler damage from
contaminated combustion air!
B Ensure adequate ventilation.
B Do not use or store chlorinated cleaning
agents or halogenated hydrocarbons
(as contained in spray cans, solvents or
cleaning agents, paints and adhesives for
example) in the boiler room.
B Do not operate the heat generator when
heavy dust contamination is present, e.g.
following building work inside the boiler
room.
B A burner contaminated during building work must be
cleaned before commissioning.
5.1 Preparing the heating system for
operation
B Create the normal required operating pressure for
commissioning (sealed heating systems) or set the
required capacity (open heating systems).
WARNING: Risk to health from potable
water contamination!
B Always observe the regulations and
standards applicable in your country for
the prevention of contamination of
potable water (e.g. by water from heating
systems).
B Observe EN 1717.
B Check that the hot gas baffles have been inserted
correctly.
For information on the quality of the heating
water see operating manual.

NOTICE: System damage due to
temperature stresses!
If the heating system is filled when hot, the
resulting temperature stresses can cause
stress cracks. The boiler will then leak.
B Only fill the system when cold (the flow
temperature should be no more than
40 °C).
B During operation, only fill the heating
system via the approved WRAS filling
method.
B Pay attention to the water quality as
specified in the operator's log, and
record the volume and quality of fill water
used.
