5.1.3.1.2 Ignite the appliance burner by switching on the electrical supply to the appliance and check that the manometer
reading is as stated below, for the gas type the appliance is adjusted for (see Data Label affixed to the
appliance reflector, below the control valve).
Category 2H: gas type G20 (natural): supply pressure 20mbar (nom)
17mbar (min)
25mbar (max)
Category 3+: gas type G30 (butane): supply pressure 29mbar (nom)
25mbar (min)
35mbar (mx)
Category 3+: gas type G31 (propane): supply pressure 37mbar (nom)
25mbar (min)
45mbar (max)
5.1.3.1.3 Switch off the electrical supply to the appliance and remove the manometer tube from the LEFT (Gas IN)
Control Valve test nipple. Screw in the test nipple sealing screw.
5.1.3.2 To check the burner setting pressure:-
5.1.3.2.1 Unscrew the sealing screw (2 turns) of the RIGHT (Gas OUT) Control Valve test nipple and connect a
manometer to this test nipple.
5.1.3.2.2 Ignite the burner by switching on the electrical supply to the appliance and check that the manometer reading
is as stated below, for the gas type the appliance is adjusted for (see Data Label, affixed to the appliance
reflector, below the Control Valve.
SRP08/SRP15/SRP30/SRP30 Hi/Lo
Category 2H: gas type G20 (natural): setting pressure - 12.0mbar.
SRP22
Category 2H: gas type G20 (natural): setting pressure - 15.0mbar.
5.1.3.2.3 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.
5.1.3.2.4 Upon obtaining the correct burner setting pressure, switch off the electrical supply to the appliance, remove the
manometer tube from the RIGHT (Gas OUT) control valve test nipple and screw in the test nipple sealing
screw. Replace the cap on the integral pressure governor of the control valve.
5.1.4 Flame Supervision .
5.1.4.1 To check the operation of the flame supervision equipment, run the appliance normally, remove the flame
sensor (grey) lead from the ignition control by gently pulling the connector using insulated pliers. Observe that
the burner flame is extinguished within 1 second.
5.1.4.2 After a 'waiting time' of 1 second, the solenoid valves and the ignition spark electrode will be re-energised and
with the flame sensor lead still disconnected, the Ignition Control will go to 'lockout condition' after a further 25
seconds (Honeywell Control) or 10 seconds (S.I.T. Control).
5.1.4.3 Switch off the electrical supply to the appliance and reconnect the flame sensor lead to the ignition control.
5.2 Standing Pilot Ignition Models.
5.2.1 Ignition
5.2.1.1 Turn on the gas supply to the appliance.
5.2.1.2 If the appliance has a thermostat fitted, ensure that it is set to the lowest temperature setting. Press slightly and
turn the control knob of the millivolt valve clockwise to the OFF position and wait 5 minutes, thus allowing any
gases to escape which may have accumulated in the combustion chamber.
