OK that is easy enough, the two slotted screw heads on each valve have to be moved a quarter turn until in line with the pipes, once the boiler pressure is between 1 and 1.5 Bar close them again, try to use the largest blade of screwdriver as smaller ones will chew the valves, you would be best advised to have proper filling loop valves with handles installed for future use
When I turn the screws water comes out is that correct? Do I turn clockwise or anticlockwise?
doesnt matter which way you turn them, very cheap filling loops tend to leak , just use a bowl and towels to catch the leaking water then contact an installer for a visit when suits you to sort it properly, make sure you close both valves again once you have enough pressure
