I'm planning to add a radiator in the kitchen so I will need to drain the whole system.
I have a worcester bosch 28i junior and it says to vent the heat exchanger after filling. I have taken the cover off and can see the area the manual points to, it's a white plastic nut with a tube attached to it.
Is it just a case of slightly opening this white nut, venting it and then tightening it up again?
