How do I bleed an oil line on a Camray 5 50/70 wall hung boiler with Riello Type 501T1K burner please (after running out of fuel) ? I'm not a specialist in any way, just a home owner. I know I have to loosen something then wait for a continuous non-spluttering flow of oil to come through. I just can't work out which 'bit' to loosen and don't want to mess anything up .
I've attached three images which will hopefully help.
