Gasmax GG-36 Natural Gas Griddle 900mm | 99Mj 22mm Steel Plate

[GASMAX_MSG]

The Gasmax GG-36 Commercial Heavy-Duty Three Burner Natural Gas Flat-Top Griddle (900mm Wide, 99 Mj/h) is a high-capacity, high-thermal-retention flat-plate searing and grilling station engineered specifically for Australian steakhouses, burger venues, pub bistros, roadhouse diners, hotel breakfast buffets, and high-volume commercial catering lines operating on reticulated mains Natural Gas. Measuring 900 mm Wide x 824 mm Deep x 546 mm High and weighing a solid 110 kg, this heavy-duty 900mm-format countertop griddle is built around an ultra-thick 22 mm polished steel hot plate that delivers superior thermal mass and heat retention. Powered by three commercial-grade steel U-shaped burners (each rated at 30 Mj/h, with a combined total heat output of up to 99 Mj/h), the GG-36 distributes heat evenly across the 900mm plate, eliminating cold spots and preventing temperature drops during continuous loading of steaks, smash burgers, bacon rashers, and fried eggs. Constructed from heavy-gauge commercial food-grade stainless steel with durable brass gas control valves, certified thermoelectric flame failure safety shut-off systems, a 3-sided stainless steel splashback guard, an integrated front grease channel with a bottom oil collector, and sturdy height-adjustable levelling legs on a standard 3/4" rear gas connection, this benchtop griddle provides reliable, heavy-duty flat-top cooking performance across demanding service rushes.

Why Australian commercial hospitality venues, steakhouses, and busy burger bars choose the Gasmax GG-36:

• Ultra-thick 22mm heavy-duty steel griddle plate — the massive 22 mm solid steel slab provides immense thermal storage, preventing plate surface temperatures from dropping when loaded with cold burger patties, portion-cut steaks, and marinated proteins.

• Triple high-output steel U-shape burners (up to 99 Mj/h total) — three independent 30 Mj/h U-shaped burners deliver dual flame paths per burner, providing even heat distribution across the 900mm wide cooking bed and fast temperature recovery during peak meal rushes.

• Three independent micro-temperature zones — equipped with three heavy-duty rotary control dials, allowing kitchen staff to operate three distinct heat zones simultaneously—searing steaks on high heat in the centre, gently cooking eggs on one side, and holding or toasting buns on the other.

• Durable commercial brass control valves — fitted with precision brass gas control valves built to withstand high heat and heavy kitchen usage, ensuring smooth flame modulation from high heat to a gentle holding simmer.

• Certified thermoelectric flame failure safety shut-off — each burner features an integrated safety thermocouple that automatically cuts the Natural Gas supply if a flame is accidentally blown out by kitchen cross-drafts or ventilation airflow.

• Wrap-around 3-sided stainless steel splash guard — high stainless steel splashback and side guards catch cooking splatters, grease droplets, and food debris to keep adjoining walls and bench space clean.

• Front grease trough & slide-out oil collector — wide front collection channel directs rendered oils, marinades, and food residue straight into a removable stainless steel grease collection drawer for quick, safe mid-service disposal.

• Field-convertible gas configuration — calibrated for mains Natural Gas with the flexibility for easy on-site gas conversion by a certified technician if future kitchen infrastructure requires LPG.

• Full food-grade stainless steel construction — heavy-duty commercial stainless steel body resists kitchen grease, corrosive cooking salts, and high-impact wear while enabling rapid end-of-shift sanitisation.

• Sturdy heavy-duty adjustable levelling legs — rugged threaded legs ensure solid, level stability on uneven commercial countertops while maintaining essential cooling airflow beneath the chassis.

• Modular stand compatibility (GG-36-SEN) — purpose-built to sit cleanly on standard commercial benchtops or bolt securely onto the matching Gasmax GG-36-SEN stainless steel equipment stand (sold separately) to create an ergonomic freestanding griddle station with an undershelf.

• Up to 4-year commercial warranty protection — backed by an Australian 2-Year parts and labour commercial warranty, extendable to an additional 2-Year parts-only warranty upon product registration within 14 days of invoice.

Technical Specifications

Daily Care, Maintenance & End-of-Shift Sanitisation

To preserve thermal plate conduction, prevent carbon build up, and protect food hygiene:

1. Plate Seasoning & Initial Setup: Prior to first use, wash away the protective factory transit coating from the 22 mm steel plate using warm water and a neutral detergent. Dry thoroughly, heat the plate gently, and apply a thin, even coat of high-smoke-point cooking oil (such as canola or peanut oil). Heat until the oil begins to smoke lightly, wipe away excess, and repeat 2 to 3 times to establish a smooth, naturally non-stick seasoned layer.

2. Mid-Service Scraping: Keep the cooking surface clear throughout trade by scraping rendered fats, marinade glaze, and meat fond into the front grease trough using a heavy-duty commercial grill scraper.

3. End-of-Shift Cleaning: At the close of service while the plate is still moderately warm (around 100°C to 120°C), apply warm water or an approved non-caustic commercial griddle cleaner. Work across the surface with a grill scraper or griddle pad to lift carbonised residues. Never dump ice cubes or freezing water onto the hot plate, as severe thermal shock can warp the 22 mm steel plate or crack internal welds.

4. Oil Collector Emptying: Slide out the bottom stainless steel grease drawer daily. Empty collected cooking fats and debris into an approved waste grease drum, then wash the drawer in a commercial pot-wash sink with warm water and a heavy-duty degreaser.

5. Nightly Anti-Oxidisation Coating: After cleaning and drying the steel plate at the end of trade, apply a light, even film of fresh cooking oil across the entire surface. This seals the steel against atmospheric moisture and prevents overnight surface oxidisation (rusting).

6. Stainless Steel Body Care: Wipe down the front control fascia, rotary knobs, and 3-sided splashback daily using a soft microfibre cloth dampened with warm soapy water, wiping in the direction of the metal grain.

Gas Installation, Ventilation & Commissioning Notice

The Gasmax GG-36 is a heavy-duty commercial gas appliance requiring certified trade installation:

1. Licensed Gas Fitter Commissioning: The unit must be installed, pressure-tested, and commissioned by an authorised, licensed gas fitter in strict compliance with current AS/NZS 5601 gas installation regulations, local council health bylaws, and manufacturer specifications. An official gas compliance certificate must be retained to validate warranty coverage.

2. Gas Supply Line & Sizing: Calibrated for reticulated Natural Gas and fitted with a 3/4" rear gas connection. Because the appliance draws up to 99 Mj/h across its three U-shaped burners, ensure incoming mains supply pipework and line regulators maintain rated operating gas pressure without pressure dips when operating alongside other line equipment.

3. Exhaust Extraction Requirements: Generating direct radiant heat, grease-laden cooking vapours, and gas combustion byproducts, the unit must be operated directly beneath an approved commercial kitchen exhaust extraction hood compliant with AS 1668.2.

4. Bench Placement & Stand Mounting: Due to its 110 kg net weight, position the unit on a reinforced commercial stainless steel workbench or mount it directly onto the matching Gasmax GG-36-SEN stainless steel stand. The supplied adjustable legs must be fitted to provide essential convective cooling airflow beneath the chassis. Maintain minimum clearances of at least 150 mm from combustible walls and 50 mm from non-combustible partitions.

Freight & Delivery Notice

Standard commercial road freight delivery is available across Australia to commercial business addresses with level ground access or loading docks.

Please contact our friendly commercial sales team prior to placing your order to confirm site access details, doorway clearances (minimum 850 mm clear opening recommended), or to add the matching GG-36-SEN equipment stand to your consignment.

Frequently Asked Questions

What are the operational advantages of steel U-shaped burners over straight bar burners?

Straight bar burners produce narrow heat bands, which can create alternating hot and cool stripes across a wide griddle surface. The Gasmax GG-36 features three steel U-shaped burners, each providing two parallel flame ribbons per control zone. This distributes heat evenly beneath the 22 mm plate, ensuring uniform edge-to-edge cooking temperatures and preventing cold spots during high-volume searing.

How does the 22mm thick plate benefit busy breakfast and burger service?

A 22 mm thick solid steel plate provides substantial thermal mass. When a chef places a full load of cold burger patties, chilled steaks, or bacon rashers onto the surface, the thick plate absorbs the thermal shock without experiencing sudden surface temperature drops. This ensures immediate searing, seals in juices, prevents meat from stewing, and cuts ticket turnaround times.

What is the advantage of pairing the GG-36 with the GG-36-SEN stand?

The optional GG-36-SEN stainless steel equipment stand matches the exact 900 mm x 824 mm base footprint of the griddle. It safely supports the unit's 110 kg weight, sets the cooking surface at an ergonomic commercial working height, frees up primary workbench preparation space, and provides a sturdy lower undershelf for storing utensils, basting pans, and oil squeeze bottles.

Can this griddle be converted to run on LPG?

Yes. While the GG-36 comes factory-configured for reticulated Natural Gas, it is designed for straightforward field conversion. A licensed gas fitter can re-jet the burners using an approved conversion kit during installation in compliance with AS/NZS 5601.

How do I activate the 4-year warranty coverage?

The Gasmax GG-36 comes standard with a 2-Year commercial parts and labour warranty. Venue operators who register their purchase online with the manufacturer within 14 days of the original invoice date receive an additional 2-Year parts-only warranty extension, providing up to 4 years of comprehensive commercial protection across Australia.
