CHECKING COMBUSTION
In order to obtain optimum combustion efficiency and to safeguard the environment, we recommend to check,
and regulate combustion using the appropriate instruments.
The most important levels to be checked are:
CO . The level of CO
2
is increased, then the CO
in CO . Acceptable values would be between 8.5 and 10% NATURAL GAS, 11-12% B/P.

CO. This indicates the presence of unburnt gas; CO, as well as lowering the combustion efficiency, is also a
danger, being a poisonous gas. The presence of CO is thus an indication of imperfect combustion, and is usual-
ly a sign that there is a lack of air during combustion. Maximum acceptable value is CO = 0.1% volume.
Flue gas temperature. This represents the loss of heat through the chimney; the higher is the temperature,
the greater is the loss of heat and the lower is the combustion efficiency. If the temperature
is too high, then it is necessary to decrease the amount of gas burnt. Acceptable temperature levels
range between 160° and 220°C.
N.B. Certain countries may have different regulations, and thus different admissible levels from those
given above.
START UP
Check the position of the ignition electrode tips and the position of the control electrode. Check the correct ope-
ration of the gas and air pressure switches. When the thermostatic line and the gas pressure switch close the
control box gives consent for the motor to be started. During this period the control box conducts a self-test of its
correct working order. If the test is positive then the cycle continues and at the end of the pre-purge period (TPR
- combustion chamber purge) the consent is given to the transformer for the spark at the electrodes, and to the
solenoid valve for opening. Within the safety time (TS) flame stabilization should occur, otherwise the system
goes in lock-out mode.
N.B. When the burner is started up, ensure that there are no leaks from the gas circuit.
N.B. Certain countries may have different regulations, and thus different admissible levels from those
given above.
PROLONGED SWITCHING OFF
If the burner should remain inactive at length close the gas cock and remove the electrical current from the
appliance.

CONVERSION FOR OPERATION WITH DIFFERENT TYPES OF GAS

Burner is delivered equipped with a head set suitable to operate with only one type of gas (natural gas or B/P).
Should you need to adapt the burner to a different type of gas (ex. from NATURAL GAS to B/P), you should
purchase the suitable gas conversion kit.
CONVERSION
To convert burner the complete head set must be repla-
ced; this is available in a conversion kit.
To replace the head set see "Maintenance".
ATTENTION
Once the conversion has been carried out it is necessary
to put the label, supplied with the conversion kit, which
indicates the figures related to the new adjustments.
This label must replace the one present on the burner
(adjustment label).
