In Germany, the device may only be used in well-ventilated rooms with a 50 mbar indoor gas pressure regulator (2 pressure levels, pressure gauge, and thermal safety device). This indoor gas pressure regulator is available as an accessory. The item is designed for use in Germany and Austria (50 mbar). This product is not suitable as a primary heating device.
