METHOD FOR CONTROLLING THE OPERATION OF CHIMNEYLESS STOVES PARTICULARLY PETROLEUM STOVES AND KEEPING THE SAFETY REQUIREMENTS OF THIS OPERATION AND APPARATUS FOR CARRYING OUT THE METHOD

摘要

The safety monitoring system detects the CO2 content of the air within the heated room, by precision measurement of the O2 content of the burner exhaust gases, to provide a corresponding voltage signal. The latter is used to provide a warning signal and delayed automatic cut-out of the burner upon reaching respective threshold values corresponding to successively low O2 contents. - Alternatively the CO content of the exhaust gases is detected to measure the CO2 conc within the room.
