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.

Choosing and fitting

Parts of this type are selected by the medium (gas), the switching range and differential, the type of connection (thread or hose spigot), and the contact rating. Before ordering, compare the setpoint range and connection geometry with the existing installation. The differential, or the gap between the setpoint and reset point, must suit the system to avoid unnecessary lockouts.

Signs of failure

Common failure modes for this type include a torn diaphragm, a blocked impulse tube, or a drifted setpoint. These faults often produce lockouts that can be mistaken for ignition problems. Checking the pressure switch, its impulse line, and the setpoint should be part of systematic diagnostics.
