What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

What if the part is discontinued?

The catalogue records what the manufacturer replaced it with, and which parts from other brands do the same job — together with the conditions that apply.

The company is based in London and ships across the United Kingdom, Europe and the rest of the world.

Is the shop open yet?

The catalogue is being assembled now. The shop opens as soon as it is ready.

Description

This control board is the burner control in a wall-hung boiler. It manages the ignition sequence and enforces safety times, including pre-purge, ignition, fuel admission, flame proving, and lockout on failure. It reads signals from pressure switches and the flame detector, and drives the ignition transformer, gas valve, and fan. It is intended for Hermann boilers.

Further details

Application	burner control in modern wall-hung boilers
Control Functions	manages ignition sequence and safety times

Choosing and fitting

Control boards of this type are model-specific and must be matched to the boiler design. Selection is by exact series and type designation, supply voltage, safety and pre-purge times, and flame detection method (ionisation, UV, or IR). The base pattern or plug connection must also match the wiring harness. Confirm the boiler model and the board's factory markings against the original before ordering.
