Information on installation
and operation
3.1
Combustion air quality
B
Keep the supply of combustion air free of corrosive
substances (e.g. halogenated hydrocarbons that
contain chlorine or fluorine compounds).
This will help prevent corrosion.
B
Never 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
Keep the combustion air supply free of dust.
B
If building work is taking place in the installation room
and creating a lot of dust, shut the boiler down.
A burner contaminated during building work must be
cleaned before commissioning.
3.2
Heating water quality
The quality of the fill and top-up water is essential for
increased efficiency, functional reliability, long service life
and for maintaining the constant operational condition of
a heating system. If the system is filled with water that has
a high calcium hardness, this will be deposited on the
heat exchanger surfaces and will obstruct the transfer of
heat to the heating water. As a result, the wall
temperatures of the stainless steel heat exchanger
surfaces will rise and the thermal stresses (loads on the
boiler body) will increase.
This is why the quality of the fill or top-up water must meet
the conditions stipulated in the operator's log provided
and be recorded in this log.
The conditions for boilers > 600 kW require general
water treatment independent of the water hardness and
the volume of fill and top-up water.

Commissioning
B
Ask your contractor to provide information about how
the boiler works and is operated.
B
Never undertake any modifications or maintenance.
4.1
Preparing the heating system for
operation
For you to be able to commission the heating system,
observe the following:
B
Check that the required operating pressure has been
built.
B
Check the flange connections and other connections
for tightness.
B
Fill the condensate siphon.
4.2
Commissioning the control unit and
burner
By commissioning the control unit you automatically
commission the burner as well. The burner can then be
started by the control unit. For further information, see the
installation instructions of the relevant control unit or
burner.
B
Use the control unit to commission the boiler.
For the installation and operation of the
heating system, observe all country-specific
standards and guidelines.
The information on the data plate is binding
and must be observed.
Open the automatic air vent valve only briefly
for ventilation.
