What it is
The Alpha 1.020671 is a burner assembly used in Alpha HE CB33 and He33 gas boilers running on LPG. It delivers the gas and air mixture to the combustion chamber, where it is ignited to produce the flame that heats the appliance's water circuit. As the component that carries the flame, it directly affects combustion quality, ignition reliability and overall boiler efficiency.
