A combination of the safe burner plug with convenient terminal blocks for connecting all burner components — simplifies installation and service.

X.Board System replaces traditional wiring harnesses in PellasX burners. All components (fan, igniter, feeder, sensors, controller) are connected to a board with labelled terminal strips. The system works with X.Plug — the safe burner plug — enabling the entire burner to be connected to the boiler in a single action.
