5.2.3.2.2 Ignite the appliance burner from the pilot burner flame by pressing and turning the control valve operating knob
counter clockwise to the 'ON' position. Check that the manometer reading is as stated below, for the gas type
the appliances is adjusted for (see Data Label, affixed to the appliance reflector, below the control valve.

5.2.3.2.3 In the event that the burner setting pressure is incorrect, remove the cap from the integral pressure governor of
the control valve. Adjust the pressure (using a suitable screwdriver) by turning the pressure governor adjusting
screw clockwise to increase, or anti-clockwise to decrease the burner setting pressure.
5.2.3.2.4 Upon obtaining the correct burner setting pressure, press and turn the control valve operating knob clockwise
to the OFF position to extinguish the appliance burner and remove the manometer tube from the Control Valve
test nipple marked 'OUT'. Replace the test nipple sealing screw, ensuring it is tight.
5.2.4 Flame Supervision
5.2.4.1 To check the operation of the flame supervision equipment, run the appliance normally, unscrew the
thermocouple nut and disconnect the thermocouple from the control valve. Observe that the appliance burner
flame is extinguished within 60 seconds.
5.2.4.2 Re-connect the thermocouple and re-ignite the appliance burner by following the procedure in section 5.2.1 of
these commissioning instructions.
6. Servicing
It is essential that at least once a year, preferably before the heating season, the appliance is serviced by a
qualified person. In exceptionally dirty conditions, such as may occur in a foundry, more frequent servicing may
be desirable.
IMPORTANT:
1. Do not rest anything, especially ladders, against the appliance.
2. Gas and electrical supplies must be isolated before commencing servicing work or replacement of
components.
3. Unless instructed to the contrary, re-assemble components in reverse order.
4. Check all joint for gas soundness after carrying out any servicing of the appliance.
5. On completion of a service/fault finding task which has required the breaking and re-making of electrical
connections, the following checks, using a multimeter must be made.
5.1 Earth continuity check.
5.2 Polarity check.
5.3 Resistance to earth check.
6.1 Ignition Electrode
6.1.1 Disconnect the black HT ignition lead from the electrode, by gently pulling the plastic shroud from the Raja
connector of the electrode.
6.1.2 Unscrew the two M4 screws securing the electrode to the flue collar assembly and withdraw the electrode.
6.1.3 Remove any foreign matter from the electrode rod and earth strap and check that the spark gap is
3.5mm. If the electrode is badly oxidised, replace the electrode (see section 7.1).
6.1.4 Upon re-assembly, ensure that the HT lead connector is securely attached to the electrode.
