3.2 Opening the gas isolation valve
▶ Push the gas isolation valve in and turn anti-clockwise until the valve
lines up with the gas line.

3.4 Switch on the boiler
▶ Put the on/off switch to position “1” ( figure 5, [1]).
3.5 Check water pressure
For the 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 ( Chapter 4.1, page 6).
▶ Top up the heating system if necessary ( Chapter 5.1, page 8).

3.6 Setting the maximum boiler temperature
▶ Set the maximum boiler temperature required in the setup menu
( Chapter 4.2).
3.7 Heating controller settings
Some of the functions described in this document change when
connecting a heating controller, i.e. room thermostat or weather-
compensated controls. The controls exchange parameters with the
boiler.
▶ You should therefore carefully read the operating instructions for the
corresponding heating controls.
