Maintenance

Boiler

Clean the boiler as indicated in its accompanying instructions in or-
der to maintain all the original combustion characteristics intact, es-
pecially the flue gas temperature and combustion chamber
pressure.

Combustion

The optimum calibration of the burner requires an analysis of the
flue gases. Significant differences with respect to the previous
measurements indicate the points where more care should be ex-
ercised during maintenance.

In case the combustion values found at the beginning of the inter-
vention do not respect the standards in force or, in any case, do not
correspond to a proper combustion, contact the Technical Assis-
tant and have him carry out the necessary adjustments.

Gas leaks

Make sure that there are no gas leaks on the pipework between the
gas meter and the burner.

Gas filter

Change the gas filter when it is dirty.

6.3

Opening the burner

See “Accessibility to the interior of the combustion head” on
page 22.

6.4

Closing the burner 

Refit following the steps described but in reverse order; refit all
burner components as they were originally assembled.

GAS OPERATION

DANGER

Disconnect the electrical supply from the burner by
means of the main system switch.

DANGER

Close the fuel interception tap.

Wait for the components in contact with heat sourc-
es to cool down completely.

After carrying out maintenance, cleaning or check-
ing operations, reassemble the cover and all the
safety and protection devices of the burner.
