Using It on the Job

1. Isolate Power: Always begin by switching off mains power to the Brivis heater at the circuit breaker and isolating the gas supply. Confirm no power with a suitable meter.
2. Access Switch: Carefully open the heater's service panel to locate the existing overheat switch. Note its mounting position and wiring connections.
3. Remove Old Switch: Disconnect the electrical leads and carefully unmount the old switch. Pay attention to how the bracket is secured.
4. Install New Switch: Mount the new Brivis Overheat Switch (BS80010744) using its 116mm long bracket in the exact same position. Reconnect the electrical leads securely.
5. Test Operation: Restore power and gas. Follow the manufacturer's procedures to test the heater's operation and confirm the new switch allows normal function without nuisance tripping.

Limitations & Safety Notes

• This switch is designed for 90°C applications only. Using it in systems requiring a different temperature cut-out may lead to safety issues or improper operation.
• Always ensure mains power and gas supply are isolated before attempting any work on ducted gas heating systems.
• Installation should be performed by a licensed gasfitter or qualified HVAC technician in accordance with Australian standards and local regulations.
• If the overheat switch has tripped, investigate and rectify the underlying cause of overheating before simply replacing the switch.

Before you fit the new switch, take a good look at the old one. If it's corroded or showing signs of heat stress, check the surrounding area for poor airflow or blockages in the heat exchanger that might be causing it to trip repeatedly. A quick fix isn't always the best fix.
