How to Bleed Radiators

1. Make sure that the CH (Central Heating) is in the off position

2. Place your bleed key on the bleed nipple (this will be at the top, at one side only and could even be at the back, but usually is at one end)

3. Turn the bleed key 1/2 a turn anti clockwise to open (you should here the air hissing)

4. When water starts to dribble out turn the key 1/2 a turn clockwise to shut it off (Do Not Over Tighten)

If you have a sealed system then the pressure will probably need topping up to 1 bar (If there isn't a gauge on or near the boiler then this instruction will not apply)
