Using It on the Job
- Always isolate power to the ducted heater at the main breaker before starting any work. Implement lockout/tagout procedures.
- Locate the existing overheat switch, typically found near the heat exchanger or combustion area of the unit.
- Carefully disconnect the electrical terminals and unmount the old switch. Note the original wiring configuration for correct reassembly.
- Mount the new Brivis 90C overheat switch (BS80010745) securely in the exact position as the old one, ensuring the short bracket sits correctly.
- Reconnect the electrical wiring, ensuring all contacts are secure and insulation is intact. Double-check all connections before proceeding.
- Restore power to the heater and test its operation. Monitor for correct cycling and ensure the switch does not trip unnecessarily under normal conditions.
Limitations & Safety Notes
- Always isolate all power sources before attempting installation or service.
- Ensure the replacement part matches the original specification (temperature rating and bracket type). Incorrect parts can lead to safety hazards or nuisance tripping.
- Installation on gas appliances should only be performed by a currently licenced and qualified person.
- This switch is not suitable for applications requiring different temperature cut-out points or alternative bracket types.
- Adhere to all Australian standards and manufacturer guidelines for ducted gas heater maintenance and repair.
Tradie Pro Tip: When you're swapping one of these out, always check for underlying issues that might have caused the original to trip. It could be poor airflow from dirty filters, a failing fan motor, or even a restricted flue, not just a faulty switch. Solve the root cause, not just the symptom.
Pair With
Consider pairing this overheat switch with other Brivis heating spare parts like control boards or new Brivis wall controllers if you're undertaking a comprehensive service. Always ensure your gas valves are operating correctly for complete system safety.
