3.21.1 Gas valve setting
Maximum heating output adjustment
• Make sure that the ambient thermostat (optional), if fitted, is set to ON.
• Select boiler operating mode "CH ONLY" by pressing the "Operating mode" button on the control panel until symbol
is shown.
• Start the "flue chimney" function (see
Flue cleaning function
on page
36
). The boiler starts operating at maximum heat output.
• If a gas switching has been made, access the programming page and set the parameter P0 based on the power and on the gas, as specified
in Tab. 8 Limits to be set for TSP parameters and default values in relation to boiler type (TSP0) - I.
• Check that P4-P5-P6-P7-P8-P9 parameter values correspond to those specified in Tab. 8 Limits to be set for TSP parameters and default
values in relation to boiler type (TSP0) - I.
• Set flue gas CO2 content by turning the ratio adjuster B (see Fig. 24 Adjusting CO2 value) and ensure that reading falls within the limits of
Tab. 13 Flue CO2 content. Let boiler flue cleaning function on and continue with the next point ”Minimum heating output adjustment" .
Minimum heating output adjustment
• Set boiler min. output operation by keeping CH - button pressed until the value corresponding to fan min. speed for the output and boiler
gas is displayed, according to Tab. 8 Limits to be set for TSP parameters and default values in relation to boiler type (TSP0) - I.
• Boiler switches to min. output operation.
• Set flue gas CO2 content by turning the offset control C (see Fig. 24 Adjusting CO2 value) and ensure that reading falls within the limits of
Tab. 13 Flue CO2 content.
• To exit the flue cleaning mode, press “Reset”.
