The centralised electronic control unit will
ignite the burner, without any manual
intervention but in response to the request
for heating. If, after approximately 10
seconds, the burner has not ignited, the
boiler safety devices will shut off the gas
and the red L.E.D.
“F”
illuminates. To reset
the ignition system, the reset button
“E”
must be pressed and released. Should the
boiler fail to ignite a second time, check
that the external gas cock is open. If the
problem persists, contact an Authorised
Service Centre.
Adjusting the heating
It is possible to set the temperature of the
heating system by adjusting the knob
“G”
between 1 and 5 until the stop on the
“ECO”
position. This will vary temperature
from approximately 40˚C to about 65˚C.
To obtain a higher temperature it is
necessary to turn the Energy Saving System
(ESS) screw
“H”
clockwise with a small
coin. The knob is now free to turn to the
MAX position,
which represents
a temperature of
about 80°C.
