2.05 Safe discharge of combustion products
The boiler comes with a FLUE GAS SAFETY THERMOSTAT, which provides a high level of safety and
control over the discharge of combustion products. This thermostat cuts off the supply of gas to the
burner in the event of a faulty flue draft.
If the FLUE GAS SAFETY THERMOSTAT has been activated, you should unscrew the protection cover
(part no. 5 in fig. 2a and 2b) and manually
“reset” the thermostat. After that, the boiler
will return to normal operation.
If the FLUE GAS SAFETY THERMOSTAT
needs to be replaced, use original
manufacturer’s parts only and make sure
the electric connections and positioning of
the bulb (see fig. 4) are correct; NEVER
UNDER ANY CIRCUMSTANCES LEAVE
THE FLUE GAS SAFETY THERMOSTAT
DISCONNECTED FROM THE ELECTRIC
CIRCUIT.
In case of frequent tripping of the thermo-
static switch, contact qualified personnel
only.
During cleaning of the draft diverter, be
careful not to damage the thermostat phial.
