7.3.1 Disconnect both the grey flame sensor lead and black HT ignition lead from the ignition control.
7.3.2 Unscrew the screw securing the red cover to the ignition control and remove the cover.
7.3.3 Unscrew the two screws securing the cable clamp to the ignition control and remove the cable clamp.
7.3.4 Disconnect the 10 way Molex electrical connector from the ignition control and gently pull the ignition
control from the gas control valve.
7.4 Ignition Control (S.I.T. 0.537.008)
7.4.1 Disconnect the grey flame sensor lead, the black H.T. ignition lead and the green/yellow earth lead from the
ignition control.
7.4.2 Unscrew the two screws securing the cover to the ignition control and remove the cover.

7.5 Injector
7.5.1 Using a ½" A/F spanner, unscrew the injector from the venturi casting.
7.6 Pre-injector
7.6.1 For appliances adjusted for category 2E+ only, there is a pre-injector fitted into the pre-injector fitting, located
between the venturi casting and the control valve elbow flange. In the unlikely event that it is necessary to
replace the pre-injector, first unscrew the four screws securing the control valve to the elbow flange and
unscrew the pre-injector fitting from the venturi casting. Unscrew the pre-injector from the pre-injector fitting
using a spanner, whilst retaining the pre-injector fitting with a second spanner or by holding in a vice.
7.7 Venturi Fabrication
7.7.1 First unscrew the four M4 screws securing the elbow flange connector to the control valve outlet port and
remove the control valve assembly complete.
7.7.2 Unscrew the four M4 screws securing the venturi casting to the plenum body end panel and carefully withdraw
the venturi fabrication from the plenum body.
7.7.3 When assembling a replacement venturi fabrication replace the venturi gasket between the venturi
casting and plenum body, also.
7.8 Twin Solenoid Control Valve (Direct Burner Spark Ignition)
7.8.1 Remove the ignition control (see section 7.3 & 7.4) and disconnect the gas supply pipe from the control valve
by unscrewing the four M4 screws securing the straight flange connector to the control valve inlet port.
7.8.2 Disconnect the electrical supply to the appliance by unscrewing the M3 screw securing the electrical
supply socket to the 4 pin plug attached to the junction box (secured to the control valve).
7.8.3 Unscrew the four M4 screws securing the elbow flange connector to the control valve outlet port and lift off the
control valve.
7.8.4 To remove the electrical junction box from the control valve first slacken the gland nut (2 gland nuts on SRP30
Hi/Lo) located in the junction box, below the control valve. Unscrew the four screws securing the cover of the
junction box and carefully lift away the cover. Unscrew the two screws securing the junction box to the control
valve and remove the junction box complete.
7.8.5 When assembling a replacement control valve, ensure that the 'O' rings, located in the elbow flange and
straight flange connectors are in sound condition and correctly positioned in the 'O' ring grooves of the
connectors.
