Burner shut down
Switch off power supply. If burner is switched off for extended pe-
riods, close manual gas cocks.
Turning the "ON/OFF" switch to "OFF" position dur-
ing the burner post-ventilation phase, the equip-
ment shuts down after a few seconds (ERROR
LOC:83).
WARNING

Gas valve adjustment
The adjustment of the output of gas is achieved by using the two
screws V1 and V2 (Fig. 15, page 21).
To alter the maximum output of gas use screw V1:
to increase the output: turn the screw towards the "+" sign;
to reduce the output: turn the screw towards the "-" sign;

Burner adjustment
The optimum adjustment of the burner requires an analysis of flue
gases at the generator outlet. In conformity with the US and Cana-
dian requirements, the burner application at the generator, the ad-
justment and the testing must be carried out in compliance with the
instruction manual of the generator itself, including the control of
the CO and CO
concentration in the flue gases and of their tem-
2
perature (See Tab. E at page 10).
Check in sequence:
-
max output
-
min output
-
ignition output
MAX output should match the value required by the boiler that is
used. To raise or lower its value, adjust the parameter P2) using
the operator panel of the control box (Fig. 22, page 26).
Measure the gas delivery on the meter to precisely establish the
burnt output.
Using a combustion analyser, measure the value of the CO
O
in order to optimise the burner calibration. The correct values
2
are: CO
8.2 - 9%.
2
To correct these values act on the gas valve in the following way:
to increase the gas delivery and the CO
towards the "+" sign;
to reduce the gas delivery and the CO
towards the "-" sign.
MIN output should match the value required by the boiler that is
used. To raise or lower its value, adjust the parameter P1) using
the operator panel of the control box (Fig. 22, page 26).
Measure the gas delivery on the meter to precisely establish the
burnt output.
Using a combustion analyser, measure the value of the CO
O
in order to optimise the burner calibration. The correct values
2
are: CO
7.8 - 8.5%.

A vent shut off system shall be applied to a baro-
metric damper installed in the venting system at the
time of conversion of the appliance.
WARNING
This will electrically disconnect the burner should
there be a blockage in the vent (chimney).
The installer must identify the main electrical power
switch and manual gas shut off valve, for emergen-
cy conditions. The burner cover must be in place
and secured before the burner is placed in opera-
tion.
To alter the minimum output of gas act on the screw V2 on the gas
valve.
Remove the protection screw and act on the intern screws with a
hex key:
to increase the output: turn the screw towards the "+" sign;
to reduce the output: turn the screw towards the "-" sign;
To correct these values act on the gas valve in the following way:
to increase the gas delivery and the CO
towards the "+" sign;
to reduce the gas delivery and the CO
towards the "+" sign;
The IGNITION output can be found within area A highlighted in the
firing rate (Fig. 4, page 10). To raise or lower its value, adjust the
parameter P0) using the operator panel of the control box (Fig. 22,
page 26).
Do not change the valve adjustments.
