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 Honeywell QM100A1009 is an ignition control box for burners. It supports gas or oil fuel and flame detection via an ionisation electrode or UV/IR scanner. The control reads pressure switches and the flame detector as monitored inputs. Its safety feature is lockout on failure. This control is not interchangeable across series.

Driven components	ignition transformer, gas valve or oil solenoid, and fan
Operating components	ignition transformer, flame sensor, burner fan, air pressure switch, fuel valve

Choosing and fitting

Replacement controls of this type are selected by matching the exact series and type designation, supply voltage, safety and pre-purge times, and the flame detection method (ionisation, UV, or IR). The base or plug pattern must also correspond to the existing wiring. Controls of this nature are normally not interchangeable across series, even within the same brand; a mismatched safety time creates a safety hazard, not just a functional inconvenience. Before ordering, verify the appliance’s existing control part number and the required safety times.
