3.2 Initial start-up

Commissioning must be performed by Qualified Personnel.
Checks to be made at initial start up, and after all maintenance operations that involved discon-
necting from the system or an intervention of a safety device.
Before lighting the boiler:
• Open any isolation valves between the boiler and the system.
• Check the tightness of the gas system, proceeding with caution and use gas leak detection fluid to
detect any leaks an connections.
• Fill the water system and make sure that all air contained in the boiler and the system has been vented
by opening the air vent valve on the boiler and any vent valves on the system.
• Make sure there are no water leaks in the system, connections or boiler.
• Make sure the electrical system is properly connected.
• Make sure that the unit is connected to a good earthing system.
• Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler.
• Vent and spin pumps.
• Ensure flue system is correctly fitted, including terminal locations.
Ignition
• Open the gas valve upstream of the boiler.
• Purge the air from the installation pipework to the appliance.
• Swith on boiler fused spur.
• Press the ON/OFF key (see fig.1).
• The boiler is now ready to function automatically whenever the externals controls are calling .
In case of an electrical power failure while the boiler is working, the burner will go out. When
power returns, the boiler will run the self-test cycle again, after which the burner will automatically
re-ignite (if there is still demand for heat).
Checks during operation
• Check for water leaks.
• Check the efficiency of the flue and air ducts while the boiler is operating.
• Check that the water is circulating properly between the boiler and the systems.
• Make sure that the gas valve modulates correctly in the heating phase.
• Check for correct ignition of the boiler by performing various tests, turning it on and off with the
room thermostat or remote control.
• Make sure that the fuel consumption indicated on the gas meter corresponds to that given in the
technical data table in section 4.4
