3.2 Commissioning

The appliance must only be commissioned for use by Qualified Personnel,
Before igniting the boiler:
• Open any on-off valves between the boiler and systems.
• Check the gas system for soundness, proceeding with care and using a leak detection water solution
to find any leaks from the connections.
• Fill the system with water 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
in 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 properly earthed.
• Check that the pressure value and gas rate for the heating system are correct.
• 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.
• Vent the air in the pipe upstream from the gas valve.
• Close any switches or insert any plugs upstream of the boiler
• Place the main switch in the ON position.
• Place knob "B" in the Winter position to a value higher than 50°C and set the room thermostat, if
fitted, 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;
- Fire the Boiler and set at full gas rate by turning P3 to maximum (anticlockwise);
- 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, tihten test point and test with leak detection fluid.
