Hi there, I've recently bought a property that had a Vaillant eco tech pro 28 boiler installed in approx. 2007. The heating works when you turn it on, however there is no timer on the control panel. The manual online doesn't explain how to set the heating to a timer. Can anyone help?

We have had a Vailant Ecotec pro 28 installed in our 2nd bedroom and have also built a cupboard to hide the boiler. I assume the boiler has a balanced flue. With this in mind do we need to drill vent holes in the new cupboard? As you can guess I'm not a plumber so any good/correct advice would...
