Designed in accordance with European standard EN 298, it guarantees maximum safety, stable combustion and efficient fuel burning in low and medium power burners. Main technical specifications Parameter Value Model Brahma VM44G Part numbers 37200752, 246.124.254 Supply voltage 220–240 V, 50/60 Hz Power consumption 30 VA Burner type Forced draught (with fan), single-stage or two-stage Combustion method Forced draught burners Fuel type Gas Operating mode Intermittent Pre-purge time (Tv) 30 seconds Safety time (Ts) 2 seconds Flame monitoring Ionization electrode Operating temperature from -10°C to +60°C Protection class IP40 Weight ~0.4 kg Service life > 250,000 cycles Key functions and features Ionization flame monitoring: Accurate and instantaneous flame detection using an ionization electrode. Non-volatile lockout: In the event of an abnormal situation, the device locks and retains this state even when power is disconnected, preventing spontaneous start-up. Manual reset: Operation can only be resumed after a lockout by manually pressing the button on the housing. This is a key safety measure. Air damper control: Possibility to connect various types of air dampers for precise flame modulation. Two independent safety contacts: Redundant gas valve control for maximum reliability. Diagnostics and indication: Possibility to connect a signal lamp for lockout indication and data transmission about operating cycle.
