The Oven can be used temporary unlimited. Use only permissible fuels. Check the manual! 

External combustion air supply

In modern, more dense buildings with controlled ventilation systems, the combustion air must be supplied from the outside so there can not arise a vacuum in the living room. This requires a separate external air supply.

Please notice:
The simultaneous operation of a stove with solid fuels and controlled ventilations systems is only permittet, if the stove has an approval under building law as independent of ambient air stove according to DBIT. The stove has to be equiped with a security device e.g. low pressure warning device that has acces to the ventilation systems and is able to turn them off in case a vacuum arises. 

Please find more information about DBIT in the users manual.

Airwash system

A deliberately conducted airflow prevents condensation and deposition of flue gases at the inside of the glass. This keeps the window clear.


The special ORANIER triple-air-system provides for the ideally dosed air supply exactly where its needed for the combustion. The desired result is an especially clean and efficient combustion.

Air-flow handle

By air circulation through the ergonomically shaped handle the temperature at the surface is largely reduced.
