Heating is unlimited at altitudes up to 1,500 m. Between 1,500 m and 4,000 m, heating is possible for short periods, such as driving over a mountain pass or taking a break during a journey. For longer stays, such as winter camping, the fuel supply must be adjusted to the altitude; an air pressure sensor can be installed for this purpose.

The kit includes an air pressure sensor unit, self-tapping screws, electrical plugs and connections, an electrical wiring harness, and an installation and operating instruction manual.
