This Brivis Heater Pilot Hot Surface Ignitor (HSI) is a direct replacement part for Buffalo and Wombat gas heating models, helping Aussie techs quickly restore reliable ignition. When a gas heater's pilot struggles to light, especially during those frosty winter mornings, a faulty HSI is often the culprit, leading to service call-outs.

I've seen plenty of these fail over time, usually from carbon buildup or simply aging out, causing intermittent firing or complete lockout. Swapping this out is a common fix.

Best For

• Australian HVAC service technicians
• Licensed gasfitters
• Competent homeowners maintaining Brivis Buffalo & Wombat gas heaters

Using It on the Job

1. Isolate power and gas supply to the Brivis heater, following lockout/tagout procedures before commencing any work.
2. Carefully remove the access panel to locate the existing pilot HSI assembly within the heater.
3. Disconnect the electrical leads and unmount the old ignitor from its position.
4. Install the new Brivis Pilot HSI, ensuring all electrical connections are secure and properly seated.
5. Restore gas and power, then test the heater's ignition sequence multiple times to confirm proper operation and check for gas leaks with an approved detector.

Limitations & Safety Notes

• Installation involves working with gas and electrical components; it must be performed by a licensed gasfitter or qualified HVAC technician.
• Always isolate power and gas before attempting any repair or replacement on gas appliances.
• Use an approved leak detection solution on all gas connections after any installation where gas lines were disturbed.
• This part is only compatible with Brivis Buffalo and Wombat models as specified.
• Follow all relevant Australian standards and Safe Work guidance for gas appliance servicing.

Before you replace the HSI, give the old one a quick clean with a soft brush – sometimes carbon buildup is the issue, and you can save yourself a return trip if it's not actually failed yet. Always check the control board for fault codes too, as other issues can mimic an HSI fault.

Pair With

Pair with a digital manometer for checking gas pressures and an approved gas leak detector to ensure all connections are sound after service. You might also consider new Brivis control boards if the issue persists after replacing the HSI.
