The Glow-Worm 20020735 Gas Section is a replacement gas valve assembly designed for use in selected Glow-Worm combi and system boilers. This component forms a critical part of the boiler’s combustion system by controlling how much natural gas is delivered to the burner during operation. When the boiler’s printed circuit board (PCB) detects a demand for heating or hot water, it sends an electrical signal to the gas section, which then opens and meters the precise amount of gas required for safe ignition and efficient burning. Accurate gas regulation is essential for maintaining consistent flame stability, correct heat output, and safe combustion performance, making this part vital to the overall reliability of the boiler.
