How do I light my Pilot Light for my potterton Profile Boiler?

How do I light my Pilot Light for my potterton Profile Boiler
Paul Harris, December 2008
The sequence is as follows...

Call for Heat (Thermostat + Programmer)
Fan Runs
Pressure Switch detects fan running - tells PCB
PCB opens pilot gas valve and makes spark
Pilot lights (automatically)
PCB senses heat from pilot light and opens main gas valve
Main Burner lights...
