Genuine and compatible Brivis ducted gas heater replacement parts — in stock and dispatched from Australia. This collection covers the components that most commonly fail or need servicing on Brivis residential heating systems: ignition and flame-sensing parts, gas valves, pressure and overheat safety switches, control boards, combustion fans and motors, heat exchangers, and the wiring looms and brackets that tie them together. Most parts here suit natural gas (NG) Brivis ducted heaters, with several items also crossing over to Braemar, Bonaire and Buffalo units that share the same Brivis-platform components. For a full breakdown of every component category, see our complete Brivis spare parts guide.
If you're diagnosing a no-ignition fault, a lockout, or a unit that won't stay lit, match your faulty part by manufacturer part number (BS… / B… codes) and gas type before ordering — the FAQ below explains how.
What's in this collection
Ignition & flame sensing
Spark pilot burners (e.g. Q3452B), pilot burner assemblies (0.46mm NG), pilot injectors, square flame-rod electrodes, and igniter/flame-sensor assemblies (e.g. 800mm). These are the first parts to check on no-ignition or short-cycling faults. If you're not sure which ignition component has failed, our step-by-step guide to diagnosing a Brivis heater no-ignition fault walks through each component in sequence.
Gas train & valves
Gas control valves including the HCCA621 platform, rectifier plugs for VK-series valves, pilot lead assemblies, and gas valve earth wiring looms. Pair valve replacements with the correct loom and gas type.
Safety switches
Manifold/air-proving pressure switches in 80Pa, 115Pa, 140Pa (NS2-1072-02) and 165Pa ratings, plus overheat / over-temperature switches in 57°C and 90°C (short- and long-bracket variants). The Pa rating and bracket length must match the original exactly.
Controls & electronics
Control boards / PCBs (multiple platform variants), wall controllers including the Networker NC-6, Touch NC-7, Touch Wi-Fi Kit and GDH manual thermostat, thermistor leads with loom and bracket, and conversion looms (e.g. EMS → HCCA621) for upgrading older control systems. Unsure whether you need the NC-6, NC-7 or Touch Wi-Fi Kit? See our Brivis controller replacement guide before ordering.
Air movement
Combustion fans, fan motors (250W / 315W / 650W), fan limit switches, run/start capacitors, and motor mounting brackets.
Evaporative cooling
Brivis evaporative cooler replacement parts including the 526 PCB add-on module for network integration, low voltage modules, and compatible electronic control boxes for CSX-series and TEK-series units. For help identifying PCB modules, TEK467 control boxes and network modules, see our Brivis evaporative cooler parts guide.
Heat transfer & misc
Heat exchangers (HX-series), 120MJ burner zip tubes, stainless steel flexible gas hoses (e.g. 1250mm), and condensation drain hoses for MPS-series units. Many of these components also suit Braemar, Bonaire and Buffalo units on the same platform — see our guide to Brivis Braemar Bonaire parts compatibility before ordering across brands.
How to choose the right part
Brivis heaters span multiple generations, so fitment is driven by exact part number, gas type, and rating — not model name alone. Read the number stamped on the failed component, confirm whether your unit runs natural gas or LPG, and check the rating (Pa for pressure switches, °C for overheat switches, wattage for motors). Our step-by-step guide explains exactly how to identify your Brivis part number from the data plate. When in doubt, send us the data-plate details and we'll confirm compatibility before you buy.
⚠️ Safety: Gas appliance work in Australia is legally restricted. Diagnosis and parts sourcing are fine for any handy owner, but installation of gas components must be carried out by a licensed gas fitter to comply with AS/NZS 5601 and your state's gas safety regulations.
