2.2.17. GAS TYPE TRANSFORMATION
WARNING
Make sure that the gas adduction tube is
suitable for the new type of fuel with which the boiler
is supplied.
WARNING
Once transformation is complete, adjust
the boiler again by following the instructions in the
relevant paragraph and apply the new identification
plate in the gas transformation kit.
WARNING
Remember that when using LPG gas,
mechanical couplings must not be sealed with flax.
In order to carry out transformation, proceed as
follows (see fig. 1):
1. cut off the electrical supply to the boiler;
2. close the gas tap;
3. remove the boiler's front casing and rotate the
control panel (refer to the 'ACCESSING THE
BOILER' chapter).
4. unscrew the gas connector '1' using a 24mm
open wrench and separate the collector '2'
from the burner '3' by unscrewing the screws
'4';
5. replace the nozzles '5' on the collector using
a 7mm socket wrench. The nozzles must be
refitted with new seals;
6. re-fit the collector '2' to the burner and replace
the connector '1'. After every dismantling and
refitting of gas connectors, carefully check for
any leaks by using soapy water;
7. affix the two 'gas data' stickers in the
transformation kit, one on the inside of the
control panel covering the existing plate, and
the other inside the front panel of the boiler,
near the data plate. On the latter, data relating
to the old type of gas in use must be deleted
with a permanent marker.
8. Set the parameter value for the new type of gas
in use (see the instructions in the 'PARAMETER
TABLE MIAB2013' and 'ACCESSING AND
PROGRAMMING THE PARAMETERS'
chapters);
9. adjust the minimum and maximum pressures
(see the 'GAS PRESSURE CHECK AND
CALIBRATION' chapter).
