Before the Flame: How Australian Food Businesses Can Make Smarter, Safer Burner Cooktop Choices

4. What Makes a Commercial Burner Cooktop Compliant?

Not all gas cooking appliances are created equal. In Australia, a certified gas appliance isn’t just one that functions well—it’s one that has passed mandatory safety testing, bears the correct compliance markings, and is listed in the national appliance certification database. Using uncertified or grey-import cooktops in a commercial kitchen is both illegal and unsafe.

Most commercial kitchen cooktops fall under the category of a Type A appliance in Australia. This classification includes gas-powered catering equipment such as burner cooktops, ovens, and fryers. Type A appliances must be certified under relevant Australian standards—primarily AS/NZS 5263 (gas appliances generally) and AS 4563 (for commercial catering equipment specifically).

Certification is performed by a Conformity Assessment Body (CAB)—such as the Australian Gas Association (AGA), Global-Mark, IAPMO, or SAI Global—who test appliances for structural integrity, ignition safety, pressure control, and combustion performance. Once certified, the appliance must feature:

• The Gas Compliance Mark (GCM) – a triangle symbol with a flame, indicating Australian approval.
• The CAB’s proprietary certification number – e.g., “GMK12345” or “AGA987654”.
• A compliance data plate fixed to the appliance, typically near the burner controls or gas inlet.

These markings must be present, visible, and verifiable through the GTRC appliance database. Any cooktop lacking these identifiers is not legally installable by a licensed gasfitter in Australia—and most councils will reject them during food premises approval.

To make things simple, KW Commercial’s burner cooktop range includes only certified, compliant units ready for legal installation. Our product listings clearly indicate the certification body and approval number, providing peace of mind from day one.

5. Spotlight on Standards: AS/NZS 5601.1:2022 Explained

When it comes to installing commercial cooktops in Australia, the most important document you’ll encounter is AS/NZS 5601.1:2022. This Australian Standard governs all gas installations—from small cafés to large production kitchens—and is legally enforced across all states and territories. Ignorance isn’t a defence: gas appliances installed without adherence to these rules can lead to failed inspections, insurance invalidation, and immediate shutdowns.

The 2022 revision of the standard replaced the older 2013 version, introducing updates that became mandatory in most regions by early 2023. For AS/NZS 5601.1 commercial cooktops, the focus lies on safety clearances, emergency shut-off valves, connection fittings, and wall surface protection. These aren’t optional—they are legislated gas installation rules in Australia and enforced by licensed gasfitters and local authorities.

📋 Key AS/NZS 5601.1:2022 Requirements for Commercial Gas Cooktop Installations

These requirements form the baseline for any compliant installation. Any gasfitter working on your site must follow them exactly—failure to do so could lead to rework, council rejection, or hazardous conditions for your team.

At KW Commercial, we collaborate with licensed gasfitters and kitchen planners to ensure the burner cooktops we supply are both compliant and installation-ready. Knowing the rules is the first step to designing a safer, smarter kitchen.

6. AS 1668.2 and The Forgotten Factor: Kitchen Ventilation

In a commercial kitchen, heat, steam, grease, and airborne particles aren’t just by-products of cooking—they’re regulatory concerns. That’s why commercial kitchen exhaust requirements in Australia are governed by AS 1668.2: The Use of Ventilation and Air Conditioning in Buildings, Part 2: Mechanical Ventilation in Buildings.

The latest edition, AS 1668.2:2024, introduces clarified design standards and updated exhaust volume calculations for commercial kitchens. The standard mandates mechanical extraction systems—typically canopy hoods—for any appliance producing high heat, smoke, or grease-laden vapour, including gas burner cooktops. Passive or open-air ventilation alone is never sufficient.

Here are the key design and compliance benchmarks:

• Minimum Vertical Clearance: 1050mm from burner to hood for gas cooktops; 1350mm for charcoal grills (measured from cooking surface to bottom of filter).
• Hood Overhang: 150mm minimum overhang beyond appliance footprint in all directions.
• Filter Requirements: Baffle-type grease filters mandatory; must be fire-rated, cleanable, and removable. Installed at a 30–45° angle.
• Discharge Method: Exhaust air must be ducted to atmosphere—typically via vertical roof discharge. Horizontal discharge near windows or intakes is prohibited unless air is treated and re-tested (2024 provision).
• Grease Management: Hood must include perimeter drip gutters (50mm x 25mm typical), with easy access for cleaning.

Local councils, such as the City of Sydney or Health Victoria, require site plans showing full ventilation layout, performance specs, and installation details. Without this, council approval for food premises fit-out will be withheld.

At KW Commercial, we work closely with exhaust system designers and mechanical engineers to ensure our equipment aligns with current ventilation regulations in Australia, helping clients pass council inspections without delays or redesign costs.

7. Council Fit-Out Rules Most Kitchens Miss

While equipment and ventilation often get the spotlight, many food premises fit-out applications fail due to issues with walls, floors, and wash stations. These may seem like minor details, but under Food Standards Code 3.2.3, they’re critical compliance requirements that councils will not overlook.

According to this national standard—enforced by all Australian states and territories—your flooring, splashbacks, and hand wash facilities must meet strict hygiene, durability, and cleanability criteria. Here are some of the most frequently overlooked requirements in council commercial kitchen design:

• Flooring Standards: Must be smooth, non-slip, impervious to water and grease, and coved at wall junctions (e.g., 75mm radius).
• Walls & Splashbacks: Must be light-coloured, sealed, smooth, and washable. Behind cooking lines, stainless steel or tiled splashbacks are required—plywood or paint is insufficient.
• Hand Wash Basin: Must be separate, within 5 metres of food prep areas, with warm running water via a single outlet, liquid soap, and paper towel dispenser.

Councils like City of Sydney and VIC Health enforce these criteria strictly during plan review and final inspections. Missing a floor coving detail or using the wrong splashback can result in costly rectification orders and delays in approval.

At KW Commercial, we support clients not only with compliant cooktops, but also with expert advice on full fit-out alignment—so you pass council inspection the first time.

8. Performance Demands: How to Choose the Right Burner

In a fast-paced food business, choosing the best gas burner for a café or restaurant isn’t about chasing the biggest number—it’s about understanding the demands of your kitchen and selecting the right tool for the job. From stir-fry intensity to slow-braised precision, each burner type offers unique performance traits.

🔥 Open vs Sealed Commercial Cooktops

• Open Burners: Exposed flame offers high-intensity heat, ideal for fast searing, wok stations, and high-turnover cooking. However, they require more cleaning as spills can enter the burner body.
• Sealed Burners: Flame ports are enclosed beneath a cap, making cleanup easier and reducing internal grease build-up. Perfect for cafés or kitchens with frequent sauce prep or lower flame requirements.

💡 Understanding MJ & BTU Ratings

MJ (Megajoules per hour) or BTU (British Thermal Units) measure gas output. Most restaurant burner MJ ratings range from 16–35 MJ/h (15,000–33,000 BTU/hr).

• 👉 16–20 MJ: Light-duty simmer and boiling (e.g., sauces, soups)
• 👉 25–30 MJ: Medium-duty general cooking (pasta, protein)
• 👉 30–35+ MJ: Heavy-duty wok or sear stations, fast recovery under load

It’s also important to consider flame control: look for burners with infinite flame adjustment or ultra-low simmer capacity (as low as 0.5 MJ/h) for menu flexibility. Some American Range sealed models excel here.

Finally, consider how many burners you need—not just now, but 12 months from now. Under-specifying reduces throughput; over-specifying wastes gas and bench space. Many KW Commercial burner cooktops are modular, allowing 2, 4, 6, or 8-burner configurations tailored to your venue’s scale.

9. Construction Matters: Material, Build & Durability

A heavy-duty cooktop isn’t just about power—it’s about surviving years of heat, grease, steam, and cleaning chemicals in a fast-paced kitchen. That’s why the material and build quality of your burner cooktop should never be an afterthought.

Start with the body: the gold standard for commercial foodservice equipment is 304 stainless steel. It resists corrosion, stands up to acidic spills and degreasers, and retains its finish after hundreds of cleaning cycles. Cheaper grades like 201 or 430 may look similar initially, but are far more prone to pitting and staining over time.

Burner grates are another make-or-break component. Look for cast iron grates designed for commercial use—these retain heat evenly, support heavy pots without warping, and can be seasoned for better longevity. Some models also offer continuous grate designs, allowing chefs to slide pans across burners without lifting, saving time and reducing spills.

Don’t overlook the controls. Quality commercial cooktops use metal control knobs (often die-cast or zinc alloy) that won’t crack or melt under constant use. Behind the surface, brass gas valves provide reliable flame control and resist wear far better than plastic or low-grade alternatives.

For an excellent example of smart construction, explore the American Range commercial burner cooktop range, available at KW Commercial. These units are engineered for true back-of-house conditions, combining durability with serviceability and long-term value.

10. Safety Features: Built-In Protection Every Kitchen Needs

In a commercial kitchen, safety isn’t optional—it’s a non-negotiable. Gas systems involve live flame, pressure lines, and heat-intensive operation, all in a high-speed environment. That’s why every cooktop must include a robust gas safety system designed to prevent accidents, protect staff, and comply with Australian regulations.

The most essential component is the Flame Failure Device (FFD). This built-in sensor detects whether the burner flame is active. If the flame goes out—due to wind, spillage, or accidental shutdown—it automatically cuts off the gas supply to prevent leakage. FFDs are required under AS/NZS 5263.0 for most commercial appliances.

Ignition matters too. Modern cooktops use electronic ignition systems—often with automatic re-ignition. If the flame is extinguished during use, the cooktop will attempt to relight it immediately. This protects both workflow and safety, reducing the chance of unburned gas accumulation. Some advanced models also include pilotless ignition, which eliminates the need for a constant open flame.

Other key systems include:

• Thermocouple Sensors – heat-activated switches tied to FFDs, monitoring burner activity.
• Gas Check Valves – prevent backflow or reverse pressure in the gas line.
• Emergency Shut-Off Compatibility – integrates with commercial kitchen isolation valves as required under AS/NZS 5601.1.

Ensuring your unit includes these cooktop safety features in Australia isn’t just smart—it’s the law. At KW Commercial, all burner cooktops we supply are vetted to include full safety integrations and match the highest compliance benchmarks.

11. Ease of Maintenance: Saving Time and Money Daily

Proper maintenance doesn’t just keep your kitchen looking sharp—it protects your team, maximises equipment life, and helps ensure your cooktop stays compliant. Knowing how to clean a commercial gas cooktop correctly can prevent common issues like clogged burners, inefficient flames, and even gas leaks.

🧼 Key Components and How to Maintain Them

• Burner Heads & Ports: Soak in hot soapy water, then use a wire brush or pin to clear each flame port. Blocked ports lead to uneven flame or ignition failure.
• Cast Iron Burner Grates: Clean weekly using degreaser or vinegar-based solution. Rinse thoroughly, dry immediately, and season lightly with oil to prevent rust. This is critical for cast iron burner cleaning.
• Drip Trays / Crumb Catchers: Empty and wipe daily. Avoid buildup that can cause smoke or flare-ups.
• Control Knobs: Remove and wipe weekly with degreaser. Avoid soaking as it may damage internal seals or wiring.

🧾 Maintenance Checklist for Commercial Burner Cooktops

Following a consistent maintenance checklist ensures better safety, fewer breakdowns, and more reliable cooking performance—especially during peak service times. If you’re investing in a high-quality burner, protect that investment with equally high-quality care.
