Printed Circuit Board for 1990 model Glow Worm KFB 50 boiler.


This printed circuit board, or PCB, is what controls the safety critical and performance levels of the boilers, such as safe start up and shut down and flame monitoring.

The 900817 could be considered to be the brain of the boiler in that it is designed to ensure the boiler operates in a fail-safe mode at all times. It is connected to and controls all of the important components and parts within the boiler, including the gas control valve, fan, flow switch, thermostats, air pressure switch and burner ignition and flame sensor.

The connection of the cables and wiring loom from these components to the 900817 is screw terminals. Through the combination of these components operated by the 900817, the burner is only permitted to light when conditions within the boiler are safe.

The control PCB also regulates the burner in response to the heating demand, by continuously monitoring the thermostats.

The PCB is powered by the mains electrical supply that is connected to the boiler.
