Initial start-up
Only qualified personnel may
carry out the commissioning
and operation of the boiler
and the instruction of the
user.
• Check the boiler and system for leaks.
Close the water outlet -
danger of
overheating and scalding.
• Check that all flue gas accessories have
been correctly installed.
• Open the shut-off valves on flow and
return.
• Switch ON the system ON/OFF switch
on the control unit.
Note:
When the heating system is started, the
display of the weather-compensated
control unit indicates all superfluous (not
connected) sensors as fault messages.
For removing these fault messages see
the control unit operating instructions.
• If the system water pressure falls below
1.0 bar, top up with water until a pressure
of 1.0 to max. 2.5 bar has been achieved.
• An error code will flash in the display, if
the boiler/burner fails to start properly.
For details about error codes see the
quick-start operating instructions.
• Instruct the customer in the operation of
the boiler. Complete the commissioning
log and hand over the instructions.
• Position the operating instructions in
the boiler room where they are clearly
visible.
Saving energy
• Instruct the customer about energy-
savings options.
• Use this opportunity for reducing the
heating temperature night operation
using control accessories.
• Adjust the temperature so you are
comfortable; every degree of room tem-
perature reduction will achieve energy
savings of up to 5%.
• Reduce the room temperature in unoc
-
cupied rooms as far as possible; please
observe frost protection.
• Ensure that all thermostatic radiator
valves are fully opened in rooms where
room thermostats are installed.
The room thermostat must not be ob-
structed by furniture or curtains.
Function checks
• During commissioning, check all control,
regulating and safety equipment for their
correct function and settings.
