1.General Notes
1.
WARNING:
All models connect to mains electrical power, so before exposing any
of the internal electrical wiring the appliance must be disconnected from electrical
power by unplugging the service cord from the electrical outlet.
2. Any servicing carried out on gas containing components where seals are broken
including manifold, regulator, valves and burner supply pipes should be followed by
a leak test. Gross leaks can be detected by connecting a manometer to the
regulator test point, pressurising the manifold and then shutting off the gas with a
ball valve. A falling manometer reading indicates a leak. Small leaks can be located
with soap and water applied at the connection.
3. Burner supply pipes leading from the burner control to the burner should have their
compression fittings tightened firmly
but not over tightened
(If a torque spanner is
used set this to 10- 15 Nm). If the tubes are damaged they should be replaced. The
soundness of the connections on the burner supply tubes can be tested by blocking
the injector orifice temporarily, eg by fitting an injector that has been blocked and
leak testing the fittings.
4. When reassembling the appliance
any earth screws and shakeproof washers
which have been removed must be re-fitted.
5. Reassembly procedures are a reversal of removal procedures.
2. Removal of Hob & Access to Internal Components
1. Isolate the appliance from electrical power.
2. Remove trivets and burners from hob.
3. Remove the control knobs from the valve shafts.
4. Remove burner mount retaining screws.
5. Remove hob mount screws which fasted the hob assembly to the burner box.
6. The hob may be lifted away from the appliance.
By removing the hob following parts are accessible for service or replacement.
•
Burner bodies.
•
Burner supply tubes.
Note:
when fitting the burner tubes to the valves
and burner bodies the nuts should be fasted with a torque of 10-12 Nm.
•
Manifold & Valves.
Note:
To remove the manifold or valves it will be
necessary to isolate and disconnect the appliance from gas supply.
•
Switch harness assembly and low voltage wiring.
•
Ignition spark plug and lead assemblies.
These are fasted to the burner
bodies by retaining clips, located on the burner body.
•
Thermocouples.
These mount to the burner bodies (retained when the hob
is fitted), and connect to the valve & T-Zero module.
•
Ignition box.
This is screwed to the base and secured by two Philips head
screws. Observe the active & neutral are correctly connected in accordance
with the marking on the ignition box when replacing this unit. Also observe
the earth ring terminal is assembled between the ignition box and the base.
•
T-Zero Module.
This is screwed to the base by two Philips head screws.
Observe all active and neutral wires connect in accordance with the
markings on the T-Zero module when replacing this unit.
