This unit is equipped with an oxygen depletion safety system (O.D.S.). The 
oxygen depletion safety system allows safe vent-free operation. When the 
normal oxygen content (20.9%) is reduced to 18%, the pilot and main burner 
will turn off and cannot be relit. 
When the pilot flame is extinguished by wind or interruption of gas supply, it will 
also turn off. Relighting is possible in this condition.

 

 

All models, except Mini 8, are fitted with a pressure regulator for Natural Gas. 

 

The thermostat fitted to the models S21 Mini 3 TE and S21 Mini 5 TE, operates 
from a maximum to a minimum input power of the main burner, as required by 
the temperature in the room.
