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

The Siemens LME41.051C2 is a combustion automaton for intermittent operation, designed for gas or gas/oil burners with 1- or 2-stage firing. It operates at a supply voltage of 230 V AC and a frequency range of 50–60 Hz. The unit consumes 12 W and has an IP40 protection class. A 10 A fuse is used to protect the control. It manages the ignition sequence, fuel admission, flame proving, and lockout functions.

Further details

Driven components	ignition transformer, fuel valve, and fan
Monitored inputs	air pressure switch and flame detector
Operating sequence	pre-purge, ignition trial, fuel admission, flame proving, lockout on failure
Replacement guidance	verify type code, system voltage and timing requirements before ordering

Choosing and fitting

Controls of this type are selected by the exact series and type designation, supply voltage, safety and pre-purge times, flame detection method (ionisation, UV, or IR), and the base or plug pattern. Always compare the type code on the existing control with the replacement data before ordering. These controls are not normally interchangeable across series, even within the same brand; a mismatched safety time creates a safety hazard, not merely an operational issue. The control may be base-mounted or plugged, and the wiring pattern must match the existing installation.
