10.3 Ignition Electrode (Fig. 104)
1. Disconnect the spark electrode lead at the
electrode.
2. Unscrew the electrode from the manifold and
withdraw the electrode.
3. Replace the new electrode in reverse order,
ensuring that the sleeving is pushed over the end
of the electrode.
10.4 Gas Valve (Fig. 105)
1. Disconnect the inlet gas cock union.
2. Remove the cover from the front face of the gas
valve and remove the electrical connections from
the tags on the gas valve.
3. Disconnect the gas valve by unscrewing the
three screws on the top face of the gas manifold. If
access to these screws is dificult the valve can be
removed with the manifold.
4. Remove the gas valve being careful not to
damage the gasket.
5. Fit the new gas valve by re-assembling all
components in reverse order, ensuring that the
gasket is properly positioned.
10.5 Thermostat Sensor (Fig. 106)
1. Disconnect the two electrical tags from the
sensor.
2. Prise the clip and sensor off the flow manifold.
3. Clip the new sensor to the manifold and
reconnect the wires. Either wire can be connected
to either spade terminal - there is no polarity.
10.6 Over-Heat Thermostat
Overheat
(Figs.106 & 107)
Thermostat
1. Disconnect the two electrical tags from the
overheat thermostat.
2. Cut off the cable tie securing the clip to the pipe.
3. Prise the clip and thermostat from the pipe,
noting its position. Disengage the thermostat from
the clip.
4. Engage the new thermostat in the clip. Prise the
clip over the flow pipe ensuring it is positioned as
previously. Take the cable tie supplied with the
new overheat thermostat and use it to secure the
clip. The cable tie must be fitted diagonally so that
it sits at both sides of the ribs on the clip.
5. Connect the two electrical tags to the terminals
on the overheat thermostat - either wire can be
connected onto either terminal - there is no
polarity.
