– Close the gas cock.
– Replace the injector (pos. 30)
RUS
and the relevant gasket (pos.
45).
– Cut the specified resistance on
the fan control board.
– Test for soundness all the gas
Adjustment and control operations must be performed with the heater in operation while heating is underway
AIR CALIBRATION
Electrically disconnect the hea-
ting probe (SM) and connect
the wires to another similar
free probe. Turn the heating
potentiometer knob to the
maximum setting, remove the
knob and connect the differen-
tial manometer (+ sign) to the
air pressure intake [7 - Drawing
1].
Sequence of operations:
1) Turn the heating power trim-
mer anticlockwise to the
bottom of the scale B [6 -
Drawing 2].
2) Calibrate the air signal using
the minimum fan power
adjustment trimmer A [4 -

3) Turn on a hot water tap to
bring the boiler up to maxi-
mum hot water power.
4) Calibrate the air signal using
the maximum fan power
adjustment trimmer D [2 -

After completion of calibration operations, check CO
values appearing in the tables, correct as necessary:
"MIN" power
"MAX" power
– Use the OFFSET screw ( 8 – Drawing 5 ) to correct CO
– Use the capacity step to correct CO

connections using soapy water
or appropriate products.
DO NOT USE NAKED FLAMES.
– Stick onto the casing panel the
plate showing the relevant fee-
ding gas.
– Proceed with air and gas cali-
bration as described below.
