This Brivis Honeywell 24V gas valve (HLVR8300A4805) is a direct replacement part for Brivis ducted gas heaters, designed to restore reliable and safe gas flow. It's an essential component for any HVAC tech or gas fitter dealing with heating system faults, especially as winter approaches.

I've seen plenty of heaters struggle to fire up, and often it comes down to a faulty gas valve, especially after years of stop-start operation in varied Australian conditions.

Best For

• HVAC technicians and gas fitters
• Brivis heater service and maintenance teams
• Apprentice gas fitters and tradies learning heating systems

Technical Specifications

What's in the Box

• One (1) Brivis Honeywell 24V Natural Gas Valve (VR8300A4805)

Using It on the Job

1. Isolate all power to the Brivis heater and ensure the main gas supply is shut off at the meter.
2. Tag out and lock out power and gas according to your company's Safe Work practices.
3. Carefully disconnect the old gas valve, noting all pipe connections and electrical wiring.
4. Install the new HLVR8300A4805 valve, ensuring all gas connections are properly sealed with approved thread sealant and torqued to manufacturer specifications.
5. Reconnect electrical wiring, ensuring correct polarity for the 2-pin connector.
6. Restore gas supply, then electrical power, and perform a thorough leak test on all gas connections using an approved leak detection solution.
7. Test heater operation, checking for proper ignition, flame sensing, and safe shutdown sequences.

Limitations & Safety Notes

• For Natural Gas applications only. Do not attempt to use with LPG or other fuel types.
• Installation and servicing must be performed by a licensed gas fitter or qualified HVAC technician.
• Always ensure gas and power are fully isolated and confirmed before commencing work.
• Refer to the Brivis heater service manual for model-specific installation instructions.
• Installation and commissioning must comply with AS/NZS 5601 and local regulatory requirements.

Tradie Pro Tip: Before you swap out a gas valve, always confirm you've got solid 24V power at the valve terminals when the call for heat is active. Sometimes it's a control board issue, not the valve itself.

Pair With

Pair with a reliable digital multimeter for voltage checks and an approved gas leak detector for commissioning and safety checks.
