7 COMMISSIONING
1. Fill and bleed the system. Fill the boiler until a pressure between 1.5 and 2 bar is achieved. The maximum working pressure is 6 bar. The boiler
(not the installation!) is automatically bled by a built-in automatic air vent.
2. Check all gas and water connections thoroughly for leaks.
3. Bleed the gas pipe.
4. As standard the boiler is set for G20 or G25 or G25.3
Check that the installation provides the right type of gas to the boiler.
5. Check the inlet pressure: 20 mbar or 25 mbar
6. Turn on the boiler by setting the main switch on the control panel of the boiler to position 1(on).
7. Generate (create) a heat demand.
8. Just before ignition the control checks if the contacts of the gas pressure, siphon pressure and water pressure are closed.
If not, the boiler will block and the display will show E76.
9. If gas, water and syphon pressure switches are o.k. the burner will be ignited.
10. Perform a thorough check on flue-gas joints for leakage.
11. Check the heat input and the gas pressure at maximum load.
12. Heat up the installation. Stop the heat demand.
13. Bleed the installation again, topping up the water system pressure if required.
14. Explain the operation of the boiler to the user.
15. Explain to the user the significance of error codes and the need to report them when requesting service engineer support.
16. After installation the datasheet as shown in chapter 9.1 should be filled in. This should be repeated at every service-interval.
17. Safely store the installation and the user manual preferably in close proximity to the boiler.
