gauge hose on the nozzle.
Start the boiler on DHW at maximum power,
activating the TEST mode (hold down the
RESET button for 10 sec and turn the knob to
select DHW at maximum power). The gas
pressure must correspond to the value set
depending on the type of gas for which it is
built boiler
see table of value changes.
,
Operation 2 preparation of the measuring material
Connect the calibrated meter to the left combustion socket by unscrewing
the screw and removing the shutter.
Operation 3
Adjust the CO2 level to the maximum gas flow
(domestic hot water)
Perform a domestic hot water extraction at the maximum water flow.
4
Select "test mode" by pressing the RESET

Wait 1 minute for the boiler to stabilize before performing the combustion
analysis.
Measure the value of the CO2 level (%) and compare it with the values
in the table below.
NB: values obtained with the lid closed.
If the value of the measured CO2 level (%) is different
according to the values indicated in the table, adjust the gas valve
according to the instructions below, otherwise go directly to operation
4.
Adjusting the gas valve to the maximum gas flow
Adjust the gas valve by turning the adjusting screw 4 clockwise to
reduce the CO2 level (one turn reduces the CO2 level by approx.
0.2-0.4%) Wait about 1 minute after each adjustment of the adjusting
screw to stabilize the value of
CO2.If the measured value corresponds to the value in the table, the
adjustment is complete, and if you do not repeat the adjustment
procedures again.
