10.3 Ignition Electrode (Fig. 114)
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. 115)
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 difficult 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.
6. Check Burner pressure is 16mbar ± 0.5 (See section 6.1
paragraph 2 if burner pressure needs adjusting).
10.5 Thermostat Sensor (Fig. 116)
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 pipe and reconnect the
wires. Either wire can be connected to either spade
terminal - there is no polarity.
10.6 Over-Heat Thermostat
(Figs.116 & 117)
Overheat
Thermostat
1. Disconnect the two electrical tags from the overheat
thermostat.
2. Remove the two screws securing the thermostat to the
pipe.
3. Ensure the thermostat mounting plate is clean and free
of debris. Fit the new thermostat using the screws
previously removed.
4. Connect the two electrical tags to the terminals on the
overheat thermostat - either wire can be connected onto
either terminal - there is no polarity.
