Using It on the Job

4. Install the new SY625430 electrode, ensuring all connections are secure and the sensor is correctly positioned.
5. Restore power and test the heater for reliable ignition and normal operation.

Limitations & Safety Notes

• Always ensure power is isolated before working on gas heating appliances.
• Gas appliance work should only be performed by a qualified and licensed gasfitter in Australia.
• Follow manufacturer's installation instructions and relevant Australian standards.
• This part is only compatible with Braemar TG5 and TH5 ducted gas heaters.

Tradie Pro Tip: Before you swap out the sensor, give the original one a good clean with a brush. Sometimes, a bit of carbon build-up is all it takes to cause an intermittent spark. If that doesn't fix it, then it's time for the replacement.
