combi boiler flush through filling loop

[dandw]

Dear Forum

I have a combi system and need to flush the system. I have filled it with sludge remover via a radiator dosing point and now need to flush it out.

I am looking for the best way to do this, in terms of connections etc, and understand that I can do this by connecting a hose to the filling loop.

I would be grateful for any advice / instructions.My boiler is a vitodens 100.

the filling loop is a non return valve....

who told you you could do it that way.

if all your doing is a warm flush, youve put your cleaner in left it for a week and now drain at lowest point normally a valve on rad...

make sure you add inhibitor when refilling.
