The boiler is supplied with a number of basic settings.
burner control - modulating on the basis of flow temperature
maximum flow temperature - 176°F (80°C)
If other values are required: see Section 8.1.6.

16. Check gas leakage control (VPS if installed):
Then set the gas leakage control pressure switch to a switch
pressure equal to 50% of the inlet pressure. Check that the
measured inlet pressure is not the (higher) closing pressure.
17. Press the reset-key to reset the boiler to 'user level'.
18. Heat the system up to roughly 176°F (80°C) if possible and
switch the boiler off.
19. Vent the system and check the water pressure.
20. The boiler is now ready for operation.
21. Set the boiler control to the required values and write down the
connected type of gas on the boiler type plate: e.g. G290 – 362
psi (25 mbar).
22. Switch the boiler on.

Set minimum load: press the [-] -key and, when L:3
appears in the display, minimum load has been set.
After minimum output has been reached, check the CO
percentage and compare it with the value in Table 18. If the
CO % level deviates from these values, set the CO
2
percentage using the correction screw of the pressure
controller on the gas block (for the 230-80 and 230-120
models, adjustments are only made at minimum load).
Remove measuring equipment and seal measuring points.
