Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to AC Volts 
Gain access to PCB (use Insulation Mat as required)
Remove connector from gas valve and make safe
Remove connector from gas valve and make safe
| WARNING! Mains voltage is expected during test, follow TOPs P4 live testing procedure |
Measurement:
Allow fan to run.
After approximately 3 seconds measure voltage between pins 3 and 4 (brown and blue) on connector X7 on the PCB.
Expected voltage approximately 240VAC.
Note:
Voltage will only be present for approximately 3 seconds during the sparking stage of the ignition cycle, if appliance locks out during testing reset as necessary until the test is complete.
