Brivis Ducted Heater Over Temperature Switch 90C

This Brivis over temperature switch (BS80009361) is a critical safety component for ducted gas heaters, designed to protect the unit from overheating by cutting power at 90°C. It's an essential spare for maintaining the safe operation of your Brivis system, especially for units manufactured after December 1998. You really don't want to skip checking these during a service; a failed overtemp switch means the heater runs until something else breaks, or worse, becomes a fire risk.

Using It on the Job

1. Isolate Power & Gas: Before beginning any work, ensure the electrical supply to the heater is switched off at the mains and physically locked out. Also, shut off the main gas supply to the appliance.
2. Access the Component: Carefully remove the heater panels to gain access to the existing over temperature switch. Note its location and how it's mounted.
3. Disconnect & Remove: Take clear photos of the wiring before disconnecting the electrical terminals from the old switch. Carefully unmount the faulty switch.
4. Install New Switch: Mount the new Brivis over temperature switch in the exact same position, ensuring it's securely fastened. Reconnect the wiring exactly as it was on the old switch.
5. Test & Reassemble: Restore gas and electrical supply. Carefully test the heater's operation to confirm the switch functions correctly and the unit runs safely. Once verified, replace all access panels.

Limitations & Safety Notes

• This switch is specifically rated for 90°C. Do not use it as a substitute for switches with different temperature ratings.
• Only compatible with Brivis ducted gas heaters manufactured after December 1998. Verify your unit's production date and existing part number.
• Installation involves working with gas appliances and electrical components. Always follow Australian standards and Safe Work guidance for isolating power and gas.
• For any complex repairs or if unsure, engage a licensed gas fitter or qualified HVAC technician.

Tradie Pro Tip

When replacing any safety limit, always double-check the part number and the trip temperature. If the original switch faulted, it's worth investigating the root cause – sometimes it's a symptom of a larger airflow issue or dirty heat exchanger, not just a failed switch.
