7.9.1 Disconnect the thermopile leads and any ON/OFF switch/room thermostat leads from the millivolt
controller of the gas control valve (connections marked TH and TP - see Fig. 9).
7.9.2 Unscrew the thermocouple nut securing the thermocouple to the control valve and remove the thermocouple.
7.9.3 Disconnect the gas supply pipe from the control valve inlet port.
7.9.4 Unscrew the four M4 screws securing the elbow flange to the control valve and lift off the control valve.
7.9.5 When assembling a replacement control valve, ensure that the 'O' ring located in the elbow flange is in sound
condition and correctly positioned in the 'O' ring groove of the connector.
7.10 Thermocouple (Standing Pilot Ignition)
7.10.1 Unscrew the thermocouple nut securing the thermocouple to the control valve and remove the thermocouple.
7.10.2 Unscrew the two screws securing the thermocouple bracket to the pilot housing and remove the thermocouple
and bracket complete.
7.10.3 Unscrew the brass locknuts securing the thermocouple to the bracket.
7.10.4 When assembling a replacement thermocouple, ensure that the thermocouple protrudes above the
bracket by 27mm before locking in position with the two brass locknuts.
7.11 Thermopile (Standing Pilot Ignition)
7.11.1 Disconnect the two thermopile leads from the millivolt controller connections (marked TP) of the gas
control valve.
7.11.2 Release the spring latch securing the thermopile in the pilot frame and pull the thermopile from the
bottom of the pilot frame.
7.11.3 When fitting a replacement thermopile ensure that the electrical leads are securely attached to the
connections marked TP.
7.12 Pilot Injector (Standing Pilot Ignition)
7.12.1 Unscrew the tube nut securing the gas supply tube to the pilot assembly and remove the tube.
7.12.2 Unscrew the pilot injector from the base of the pilot frame.
7.12.3 When fitting a replacement pilot injector, ensure that the correct size injector is fitted, relative to the gas type the
appliance is adjusted for (see Data Label affixed to the appliance reflector, below the control valve.
Natural Gas - Injector marked TJ020 LPG - Injector marked TJ012
7.13 Pilot Burner Frame (Standing Pilot Ignition)
7.13.1 Disconnect the gas supply tube from the pilot frame. (see 7.11).
7.13.2 Unscrew the two screws securing the thermocouple bracket and pilot frame to the pilot housing assembly and
remove the pilot assembly. Unscrew the pilot injector from the base of the pilot frame.
7.13.3 When assembling a replacement pilot frame, ensure that the correct pilot injector relative to the gas type used,
is fitted. (see 7.11.3 above).
7.14 Reverberatory Screen
7.14.1 At the opposite end of the appliance to the controls, remove the two screws securing the reflector end panel to
the flue collar.
7.14.2 Unscrew the two M4 screws securing the flue collar to the plenum body end panel and remove the flue collar.
7.14.3 Carefully slide out the reverberatory screen along the side retaining rails.
