What it is

The Broag safety control box for gas is a control component used on Broag Commercial gas-fired boiler plant. It forms part of the burner control and safety interlock circuit on the appliance, managing the sequence and shutdown logic that keeps the boiler operating within safe limits. This part is supplied under Broag part number 8502-5578.

Signs this part needs replacing

  • The boiler fails to complete its ignition sequence and drops to lockout.
  • Lockout recurs after resetting, with no change to the burner sequence.
  • The appliance does not respond to a call for heat from the controls.
  • Intermittent shutdowns or unexplained loss of firing during operation.
  • Visible damage, burning or moisture ingress at the control box or its plug connections.

Before you order

  • Confirm the appliance model is the Broag Commercial GAS 360S before ordering.
  • Compare the part number on the existing control box against 8502-5578 or 85025578.
  • Check that the fault lies with the control box rather than the ignition, detection or gas valve components in the same circuit.
  • Isolate the electrical supply and gas before removing or fitting the control box, and commission the appliance after fitting.
