Ok, i have managed to locate the tap (control screw) thanks to the
post below. How long do i leave it open for; how do i know when the
system is pressurised?

When the pressure gauge says so - usually 1 - 1.5 bar unless the boiler's
on the ground floor of a building 2 storeys high in which case maybe 1.5
- 2.
