Control box terminals

The control box base is the mounting and wiring platform that anchors the burner control unit to the appliance chassis. It carries the terminal block through which mains supply, flame detector, valve outputs and lockout signal are distributed, and it positions the plug-in control box so that the contact pins engage correctly every time the unit is removed for service or replacement.

Choosing the right base means matching the terminal layout and pin configuration to the specific control box model, not just the brand. Check the number of terminals, their pitch and labelling against your existing wiring diagram, and confirm the mounting footprint fits your burner chassis. Where your original part number belongs to Brahma, Honeywell or Siemens, that reference can be cross-matched to the equivalent item in this section.
