This Bonaire Vulcan gas heater flame sensor is a critical spare part for HVAC techs and competent DIYers, ensuring your heating system ignites reliably. In the cooler Australian months, you need your ducted gas heater running right, and a faulty flame sensor can stop it dead.
I've seen plenty of nuisance call-outs just because a flame sensor was gunked up or had a weak signal; replacing it often sorts out intermittent ignition faults.

Using It on the Job
- Isolate power to the gas heater at the main switchboard and ensure gas supply is turned off at the isolation valve.
- Locate the existing flame sensor in the burner assembly. Take note of its exact position and how it's connected.
- Carefully disconnect the wiring and remove the old sensor, ensuring not to damage any surrounding components.
- Install the new Bonaire 50mm flame sensor, securing it properly and reconnecting the wiring as it was.
- Restore gas and power to the unit, then test the heater's ignition sequence. Monitor for consistent flame detection and proper operation.
- Perform a gas leak check around any disturbed gas connections using appropriate detection methods.
Limitations & Safety Notes
- Only compatible with the specified Bonaire Vulcan gas heater models.
- Installation and servicing of gas appliances in Australia must be carried out by a licensed gas fitter.
- Always isolate electrical power and turn off the gas supply before commencing any work on heating systems.
- Adhere to all relevant Australian standards and Safe Work guidance for gas appliance maintenance.
Before you swap out a flame sensor, give the old one a good clean with some fine steel wool. Sometimes, carbon build-up is all that's stopping it from doing its job, saving you a trip or a new part.
Pair With
Pair with gas leak detection fluid, a quality multimeter, and a pressure gauge for comprehensive diagnostics when troubleshooting gas heater issues.
