Boiler Shut Down?

You need to repressurise the system using the filling loop. The engineer who installed the boiler should have taken you through this procedure before the final 'hand over' or it should be explained in the boiler hand book.
Whilst it is not uncommon for systems to require topping up it does seem a little odd to loose the pressure so quickly also given the small amount of use. It could mean you have a leak in the system somewhere. My best advice would be to check with your installer with reference to any instalation warranty and to get them to return and resolve the problem.
