    Design information (cont.) However, the high safety standard derived from the use of an exter- nal safety solenoid valve has proved to be valuable. We therefore recommend the continued installation of an external safety solenoid valve when installing the Vitodens in rooms below ground level. This requires the internal H1 extension.
