What it is

The Siemens LFE10 is a control box gas flame relay, a burner control unit that manages ignition sequencing and flame supervision on gas-fired appliances. It is supplied without a base, so the existing wiring base is retained and the control box is simply exchanged. The unit is a service item for engineers working on gas boiler and burner controls.

Before you order

  • Confirm the control box currently fitted carries the LFE10 reference before ordering.
  • The base is not included, so check that the existing base is present and in serviceable condition.
  • Note the terminal wiring and connections on the existing base before removing the old control box.
  • Check the pin arrangement on the existing base matches the connections on the replacement unit.
