Technical Specifications

What's in the Box

• 1 x Braemar THM 618 PCB Circuit Board (PN. 628592)

Using It on the Job

1. Isolate Power: Always disconnect the main power supply to the ducted heater at the switchboard before beginning any work. Use lockout/tagout procedures if available.
2. Access Panel: Remove the heater's access panel to expose the control board enclosure.
3. Photograph Connections: Before disconnecting, take clear photos of all wiring connections to the existing PCB. This helps immensely during reassembly.
4. Remove Old Board: Carefully disconnect all wiring and mounting screws holding the old PCB in place.
5. Install New Board: Mount the new Braemar THM 618 PCB, ensuring it's correctly seated. Reconnect wiring exactly as per your photos.
6. Test Functionality: Restore power and run through the heater's cycle, checking for proper ignition, fan operation, and zone control functionality.

Limitations & Safety Notes

• Installation of gas appliance parts must be performed by a qualified and licensed gas fitter or HVAC technician.
• This PCB is specific to the Braemar THM 618 model and BSC 2006 zone control. Do not attempt to fit it to incompatible units.
• Always follow manufacturer's installation guidelines and relevant Australian safety standards.
• Electronic components are sensitive to static discharge; handle with care.

Tradie Pro Tip

Before pulling the old board, always double-check the model number on the heater itself and the part number on the PCB. A quick cross-reference can save you a return trip and a lot of headaches, especially with sensitive electronic parts.

Pair With

Consider pairing this replacement PCB with new flame sensors or igniters if your unit is showing intermittent ignition faults. A good multimeter and a set of insulated hand tools are also essential for safe and effective troubleshooting.
