REPLACEMENT
OF
PARTS
SUBJECT
TO
CHANGE
Sealed components must not be tampered
with. After each intervention, if necessary,
check for the absence of gas leaks.
To reach electrical componenets remove control
panel; for interventions on fan motor proceed also
from behind of the appliance.
IMPORTANT
Before carrying out repairs, unplug
appliance from mains disconnecting the main
switch (ranges with electric oven).
Burner, Pilotburner, Thermocouple of cooking hob
– Remove control panel of appliance together with
grids and replace the component.
Gas cock of cooking hob
– Remove control panel of appliance and replace
the component.
Gas cock, Piezoelectric igniter of gas heated oven
– Remove control panel of appliance and replace
the component.
Burner, Thermocouple, Ignition spark plug of gas
heated oven
– Remove control panel of appliance, oven floor
and replace the component.
Heating elements in electric oven
– Working inside the oven chamber and from behind
of the appliance, disconnect the heating element
and remove the screw from the flanges.
Switch, Temperature regulation and safety
thermostats (electric oven)
– Pull out the control knobs. Remove the front
control panel. Remove the fastening screws on the
component to be changed. Extract the bulb
(thermostat) from the bracket located inside the
chamber. Change the faulty component.
START
-
UP
Function check
– Start-up the appliance according to instructions
for use and check the regularity of the burner
ignition, the absence of gas leaks and the
efficiency of the burnt gas exhaust system as
well as of the ventilation system.
– If necessary consult paragraph “Analysis of
several failures”.
Checking electrical system (combination ranges)
– Switch on the cooker oven, following the
instructions given; make sure that, controls,
heating element and fan are in good working
order.
Nominal heat input check
– After installation or adjustment to another type
of gas and at each maintenance intervention
check the heat input of the appliance.
– The nominal heat input is stated in the
“Technical data” table.
– The appliance operates at the nominal heat
input when the nozzles assembled are suitable
for the type of gas used and the inlet pressure is
the one indicated in Table T1 and the electrical
power is the one stated in Table T7.
– For the measurement of the inlet pressure read
paragrah “Inlet pressure check”.
Inlet pressure check
– For the measurement of the inlet pressure use
a gauge having a minimum definition of
0.2 mbar.
– Remove control panel of appliance, remove seal
screw from upstream pressure tapping and
connect the gauge pipe.
– Carry out the measurement with appliance on.
– Disconnect the gauge pipe and screw down seal
screw.
– If the inlet pressure value is not within the
limits indicated in Table T3, interrupt the
operation of the appliance and contact the gas
delivery body.
ATTENTION
If the inlet pressure or power supply values are
not within the limits indicated in Tables T3 and
T7, interrupt the operation of the appliance and
contact the gas or electricity delivery body.
