Using It on the Job

1. Isolate Power: Always begin by switching off power to the ducted gas heater at the main breaker. Use a lockout tagout device for safety.
2. Access Fan: Locate and carefully access the existing combustion fan within the Brivis heater cabinet.
3. Disconnect & Remove: Disconnect all electrical wiring and mounting hardware from the old fan. Make notes or take photos if needed to remember connections.
4. Install New Fan: Mount the new Brivis Combustion Fan securely in place, ensuring all electrical connections are correct and tight.
5. Test Operation: Restore power and initiate a test run of the heater, checking for proper fan operation and safe flue gas ventilation.

Limitations & Safety Notes

• Always ensure power is completely isolated and locked out before commencing any work on the heating unit.
• This fan is specifically for Brivis Star Pro HX series ducted gas heaters and may not be compatible with other models.
• Installation of gas appliance components should ideally be performed by a qualified and licensed gas fitter or HVAC technician.
• Follow all manufacturer guidelines and relevant Australian gas appliance safety standards during installation and testing.

When fitting a new combustion fan, it’s a good habit to give the entire flue system a visual check for blockages or signs of corrosion, especially if the old fan failed unexpectedly. A clean flue makes the new fan's job easier.

Pair With

Consider pairing this with other Brivis heating spares like control boards, gas valves, or pressure switches to keep common replacement parts on hand for faster service calls.
