Check the indicator’s level and if it is less than one then the pressure of the boiler might need a little bump. The next thing you have to do is located the filling loop which is normally located at the bottom of the boiler. Turn the boiler off and check that the hose ends are connected to the valves. Opening the valve will allow water inside the system. Monitor the rise of the pressure indicator and close the valve once it reaches 1.5. You can now try turning on your boiler unit.

A radiator key can then be used to connect to the valve. Use a cloth and rotate the key reverse clockwise. You know that gas is being bled if there is a hissing sound. After letting all the gas out, close the valve.
