Poorly fitting external upvc doors?
 
                We have 2 external upvc doors, both of which have never fitted properly.
There are 2 allen-key operated adjusters on each hinge but am not sure which one does what.
Top one appears to lift door up, bottom one appears to move it to & from the frame.
Problem is the door not closing to the frame fully - can lock & unlock it, but is draughty.
