I have a upvc door with hinges the same as the one in the diagram from
the bottom of following page:-

http://www.upvcdoorcompany.co.uk/guarantee.htm

The 3 hinges in total both have 2 allen key adjustments.

My question:-

I presume the key at the bottom of the hinge adjustments the height of
the door, please correct me if I'm wrong, but what does the key on the
side do? (Position A)

Any help would be greatly appreciated.

Neither adjustment affects the height of the door on the hinge side - but if
you move the top or bottom away from the frame, the angle - and the height
of the remote side - will change.

IIRC from when I did mine, the hinge pin can be rotated in an eccentric
housing - which has the effect of simultaneously moving the door towards or
away from the frame in the plane of the door - and into or out of the room
(in the plane perpendicular to the door). The other adjustement (A on your
diagram) just moves the door towards or away from the frame in the plane of
the door. So you need to adjust the hinge pin first, to get the door in the
right in/out position. *Then* adjust A to get it square in the frame, and so
the locking bolts all line up ok.

ISTR that I needed 2 different sizes of Allen key for the two adjustments -
I forget what size they were, but I had them in my set - or rather in a set
of hex bits which fit into a screwdriver-type handle.
