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.
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.
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), the Networker NC-6 wall
controller, thermistor leads with loom and bracket, and conversion looms
(e.g. EMS → HCCA621) for upgrading older control systems.
Air movement
Combustion fans, fan motors (250W / 315W / 650W), fan limit switches, run/start capacitors,
and motor mounting brackets.
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.
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).
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.
