from the shifter place the bike in it's lowest gear (big rear small front).
undo the cable clamp on the front mech.
Make sure the front mech is parallel to chainrings, make sure your barrel adjuster on shifter or cable stop on down tube is screwed all the way in then un-screw it about 2 turns.
adjust the lower limit screw so that there is about 2 mm of clearance between the chain and the rear mech on the frame side.
re-clamp the cable so pulling though slack, but not so much that it's super tight. Clamp cable.
Now tweak barrel adjuster at shifter or cable stop to fine tune front mech.
