What it is

The Firebird ACCCOMFSW is a flow switch supplied as Sika VKX15MIFIREB03 for Firebird oil-fired boilers. It monitors water flow through the appliance and signals the control circuit, allowing the burner to run only when flow is proven. It is a serviceable component within the boiler's safety and control chain.

Signs this part needs replacing

  • The burner fails to fire or repeatedly locks out despite a call for heat.
  • The boiler runs intermittently, cutting out shortly after start-up.
  • No heating or hot water while the pump is running and flow is present.
  • Fault codes or lockout indications linked to flow proving.
  • The switch shows physical damage, contamination or a sticking mechanism.

Before you order

  • Confirm the appliance is a Firebird oil-fired boiler and check the model against the manufacturer's parts list.
  • Check the marking on the existing switch reads Sika VKX15MIFIREB03.
  • Confirm the fault lies with the flow switch rather than the pump, system flow or control board.
  • Have the boiler isolated and the system drained or valved off as required before fitting.
