3.2 Commissioning

The appliance must only be commissioned for use by Qualified Personnel,
Before igniting the boiler:
• Open the isolation valves between the boiler and systems.
• Check the gas system for soundness, and ensure their are no leaks.
• Fill the system with water to approximately 1bar pressure and ensure that the air contained in the
boiler and the system has been completely vented, by opening the air vent valve on the boiler and
any vent valves installed within the system.
• Check that there are no water leaks in the heating system, in the domestic hot water circuits, in the
connections or in the boiler.
• Check the correct connection of the electrical system.
• Check that the appliance is correctly earthed.
• Check that there are no flammable liquids or materials in the immediate vicinity of the boiler.
Igniting the boiler
• Open the gas isolation valve upstream of the boiler.
• Purge the air in the gas supply pipework upstream from the gas valve.
• Place the main switch in the ON position.
• Place the control knob "B" in the Winter position to a value higher than 50°C and set the room ther-
mostat, to the required temperature value. At this point, the burner will ignite and the boiler will start
operating automatically, managed by its control and safety devices.
• Checking gas inlet pressure
- Connect a pressure gauge to inlet test point;
- Check the pressure gauge is reading 20 mbar (+/-1 mbar);
- Check that this pressure remains as above with any other gas appliances in the house turned on;
- If the pressure is below this reading it should be investigated before continuing as this is a sign of
an incorrect or partially blocked gas supply;
- Turn-off appliance;
- Remove pressure gauge, tighten test point and test with leak detection fluid.
• Check that the burner pressure and gas rate for the heating system are correct.
