3.3 Opening service valves
▶ Open both service valves so that the tap lines up with pipework.
Fig. 3 Opening service valves
3.4 Switch on the wall mounted gas condensing boiler
▶ Put the ON/OFF switch to position “1” ( figure 5, [1]).
3.5 Check water pressure
For the wall mounted gas condensing boiler to work efficiently, the
normal water pressure must be between 1.0 and 2.0 bar.
▶ Ask the installer whether a higher pressure is necessary.
▶ Read off the water pressure on the display.
▶ Top up the heating system if necessary ( Chapter 6.1, page 7).
Fig. 4 Read off the water pressure
3.6 Setting the maximum boiler temperature
▶ Set the maximum boiler temperature required in the setup menu
( Chapter 4.2).
The heating and DHW operations can be switched on and off
independently of one another.
3.7 Setting the user interface
Some of the functions described in this document change when
connecting a user interface. The user interface exchanges parameters
with the wall mounted gas condensing boiler.
▶ You should therefore carefully read the operating instructions for the
user interface.
