you need a filling loop key,white plastic t key with two black gasket rings around the tip (try ebay thats where i got mine) then insert the key in the black hole underneath boiler sort of on the left near the front ,turn a quarter turn then there is a white/grey knob in my case its a stubb turn anticlockwise get the pessure up to 1.5 bar then bleed each rad and repeat till happy!
