Using It on the Job

1. Always isolate power to the Brivis ducted heater at the main switchboard and implement lockout procedures before starting any work.
2. Locate the existing thermistor assembly within the heater cabinet and carefully disconnect its wiring.
3. Remove the old thermistor and bracket. Mount the new Brivis Thermistor Lead (BS80019789) using the integrated bracket.
4. Connect the new thermistor's wiring loom securely to the control board or designated connection points. Double-check all connections.
5. Restore power and test the heater's operation, ensuring the thermistor provides accurate readings and the unit cycles correctly.
6. Properly dispose of the old component according to local waste guidelines.

Limitations & Safety Notes

• Designed specifically for Brivis gas ducted heaters. Not suitable for other brands or system types.
• Gas appliance servicing, including component replacement, should only be performed by a qualified and licensed gasfitter in Australia.
• Always follow manufacturer's installation instructions and relevant Australian standards.
• Ensure all electrical connections are secure and corrosion-free before restoring power.

Tradie Pro Tip: When you're swapping out a thermistor, it's a good idea to also inspect nearby wiring for any signs of heat damage or rodent chews, especially on older units. A little preventative check now saves call-outs later.
