I have FGS storad in my flat which was built in the late 80s. The tenant who lived in there before we moved in maliciously removed the two knobs on the radiator one the left side which is the convector and one on the right side which is storage. I use the heater but I cannot control it . on top of the heater there is an off and on button. I do not know the model or any number. Please help
