Operation with external air supply
The German institute for constructional engineering (DIBT) has given the Osca the general technical approval for operation with
external air supply.. If the combustion air is being supplied directly to the furnace by an air-tight pipe including closing
mechanism from the outside, then the stove may be used in residential property with mechanical ventilation.
If the stove in being used like that, a multiple stove installation on the same chimney is forbidden.
This stove has been approved by the German DIBT.
