Innovative new electronic gas and air modulation system, providing the following benefits: Accurate electronic modulation of gas and air for clean, low emission combustion. Wide modulation range of 1:6 (16%) provides a low minimum output for use in properties with small heat loads or where multiple heating zones have been used. Self-adjusting range rating function, which learns the maximum heating requirement of the system without the need for setting, ensuring the most efficient mode of operation. Assured Comfort (back-up mode) - in the unlikely event of a combustion fault, the boiler will revert to the last known operating condition to provide a degree of heat and hot water until the fault is fixed. Self-diagnostic checks completed on first ignition to ensure correct gas type is being used. Checks made every 30 seconds ensure optimum combustion and eliminate the need to check and set CO2 levels Burner is automatically monitored to ensure low combustion noise and optimised burner settings, using our innovative new Flame Lift Detection System.
