COMMISSIONING 6. Adjusting the CO2 Intermediate Power Draw off the domestic hot water at the maximum water flow rate. Select the Chimney function by pressing the RESET button for 10 seconds. WARNING! When the cleaning function is activated, the temperature of the water coming out of the boiler may be more than 65°C. The display will visualise the Chimney Function active at Intermediate Power Intermediate Power Max power DHW Max power CH Chimney active Wait 1 minute for the boiler to stabilise before carrying out the combustion analyses. Read the CO2 value (%) and compare it with the values given in the table A below: Table A Gas Intermediate Power ALTEAS ONE NET 30/35 CO2 (%) Max Power DHW G20 8,8 ± 0,7 G30 / G31 10,5 ± 1,0 Min Power Minimum power Press the button > to select Minimum power The display will visualise the Chimney Function active at Minimum power Max power DHW Max power CH Chimney active Wait 1 minute for the boiler to stabilise before carrying out the combustion analyses. Read the CO2 value (%) and compare it with the values given in the table A. If the C02 (%) value is correct proceed to the next operation. Minimum power f the value of CO2 detected, differs from the values given in the table, press the button OK. The display, after a few seconds, shows an adjustment - + bar. Press the buttons b to adjust the value. It’s possible modify the value of ± 0,5%. Press OK to confirm and proceed to the next operation. 7. Ending the adjustment Exit cleaning mode by pressing RESET. Stop the draw-off. Verify and repair any leaks of gas. Refit the blanking cover for the combustion outlets.

COMMISSIONING Maximun Heating Power adjustment The maximum heating power can be adjusted to between the maximum power allowed by the boiler and the minimum power). The display shows the value between “100” and 0 of this interval. To check the maximum heating power, access menu 2/sub menu 3/parameter 1, check the value and, if necessary, modify it as indicated in the Gas Pressure table. The table indicate the existing relationship between the gas pressure at the burner and the boiler power level in heating mode. Checking slow ignition power The soft light can be adjusted between the maximum power and the minimum power. The display shows the value between “100” and 0 of this interval. To check the slow ignition power, access menu 2/sub menu 2/ parameter 0. If needed, change the parameter value until suitable pressure is achieved. ALTEAS ONE NET 35 ALTEAS ONE NET 30 31 28 Heating ignition delay adjustment This parameter – menu 2/sub menu 3/parameter 5 - can be used to manually (0) or automatically (1) set the delay time before the subsequent reignition of the burner after it has switched off on reaching the desired temperature. By selecting manual, it is possible to set the delay in minutes using the successive parameter (menu 2/sub menu 3/parameter 6), to a time between 0 and 7 minutes. Automatic selection means that the boiler will establish the delay time based on the set-point temperature. 3,5 3,0 Table summarising changes parameter ALTEAS ONE NET 30 35 G20 G30 G31 G20 G30 G31 Lower Wobbe index (15°C, 1013 mbar) ( MJ/m3) 45,67 80,58 70,69 45,67 80,58 70,69 Supply gas pressure min-max (mbar) 17-25 25-35 25-45 17-25 25-35 25-45 Slow ignition 220 42 43 Maximum C.
