Gasmax RB-4ELPG 4 Burner LPG Gas Cooktop 602mm | 80Mj Commercial

[GASMAX_MSG]

The Gasmax RB-4ELPG Commercial Heavy-Duty Four Burner LPG Gas Cooktop (602mm Wide) is a high-output benchtop boiling table engineered specifically for Australian commercial cafes, restaurant cooklines, catering trailers, food trucks, and regional venue kitchens operating on bottled Liquefied Petroleum Gas (LPG). Measuring 602 mm Wide x 824 mm Deep x 574 mm High and weighing a solid 60 kg, this heavy-duty 600mm-format benchtop boiling top features four high-intensity commercial open gas burners delivering a combined total heat output of 80 Mj/h (20 Mj/h per burner). Designed for rapid sautéing, stockpot simmering, frying, and continuous pan work during peak service hours, the RB-4ELPG incorporates flat heavy-duty cast-iron trivets for smooth pan sliding, push-button piezo ignition, certified thermoelectric flame failure safety protection, an integrated stainless steel rear splashback, slide-out stainless steel crumb and drip catchment pans, and height-adjustable levelling feet (up to 45 mm adjustment) on a standard 3/4" gas regulator connection.

Why Australian commercial hospitality venues, caterers, and food trucks choose the Gasmax RB-4ELPG:

• Quad high-output 20 Mj/h open gas burners (80 Mj/h total) — four heavy-duty burners deliver concentrated heat and rapid pan response, maintaining high sautéing and boiling temperatures during high-volume service rushes.

• Heavy-duty flat cast-iron trivets — flat-profile cast trivets create an uninterrupted cooktop surface, allowing chefs to slide heavy stockpots, sauté pans, and woks between burners without lifting or spilling hot liquids.

• Independent multi-zone rotary controls — four heavy-duty commercial control dials provide precise simmer-to-boil flame adjustments across four separate pans simultaneously.

• Dependable piezo ignition with continuous pilot — push-button piezo ignition system lights burners effortlessly without relying on handheld matches or open taper lighters.

• Full thermoelectric flame failure safety shut-off — fitted with certified flame failure safety valves on each burner that instantly cut off the LPG supply if a flame is blown out by kitchen cross-drafts, sudden breezes, or pot boil-overs.

• Integrated stainless steel rear splashback — high rear stainless steel splash guard prevents hot grease, boiling sauce splatters, and food debris from falling down behind cookline equipment and adjoining walls.

• Full food-grade stainless steel construction — heavy-gauge commercial stainless steel chassis, front fascia, and side panelling resist kitchen impact, corrosive cooking salts, and acidic sauces while enabling rapid sanitisation.

• Slide-out stainless steel drip pans — removable under-burner drip trays capture dropped food particles, grease runoff, and boil-over liquids for quick end-of-service clearing and washing.

• Modular stand compatibility (RB-4-SEN) — purpose-built to mount directly on the matching Gasmax RB-4-SEN stainless steel equipment stand (sold separately) to create an ergonomic, freestanding cooktop suite with an undershelf.

• Heavy-duty adjustable levelling feet (45mm range) — sturdy threaded levelling feet provide up to 45 mm of height adjustment, ensuring stability on uneven counters and maintaining the clearance needed for airflow and drip tray removal.

• Up to 4-year 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.

Daily Care, Maintenance & End-of-Shift Sanitisation

To preserve gas combustion efficiency, prevent grease fires, and maintain kitchen hygiene:

1. End-of-Service Cast-Iron Trivet Cleaning: At the close of trade, remove the heavy-duty cast-iron trivets once they have cooled down. Scrub away baked-on sauces and carbon build-up with a stiff wire or brass grill brush. Periodically season trivets with a light wipe of food-grade vegetable oil to prevent surface oxidisation.

2. Burner Cap & Port Maintenance: Inspect the open burner caps and flame ring ports daily. If ports become clogged with boiled-over sauces, starch, or marinades, remove the burner caps and clear the holes using a wire probe or stiff bristle brush. Ensure burners are completely dry before relighting.

3. Drip Pan Clearing: Slide out the stainless steel crumb and drip catchment pans beneath the burners at the end of each shift. Empty accumulated fats, food debris, and boiled-over liquids into a designated waste container, then wash in a commercial pot-wash sink with warm water and a neutral degreaser.

4. Stainless Steel Body & Splashback Care: Wipe down the front control fascia, side panels, and rear splashback daily using a soft microfibre cloth dampened with warm soapy water, wiping in the direction of the metal grain. Never dump cold water directly onto hot cast-iron trivets or burner heads, as thermal shock can fracture cast iron.

5. Ignition & Thermocouple Inspection: Keep the piezo spark pins and flame failure thermocouples clear of grease and carbon crusting. A clean sensor probe guarantees instant ignition and reliable flame safety response.

Gas Installation, Ventilation & Commissioning Notice

The Gasmax RB-4ELPG is a commercial gas cooking 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 universal Liquefied Petroleum Gas (LPG) and fitted with a 3/4" gas inlet and 3/4" regulator. Because the appliance draws 80 Mj/h across its quad burners, ensure LPG bottle manifolds, pigtails, and dual-stage gas regulators maintain rated operating pressure without pressure drops when running at full capacity alongside other kitchen equipment.

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

4. Bench Placement & Stand Mounting: When installing on a commercial stainless steel benchtop, the supplied adjustable legs must be fitted to maintain essential airflow under the chassis and allow unobstructed access to the slide-out drip trays. Alternatively, mount the unit directly on the dedicated Gasmax RB-4-SEN stainless steel stand. 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. Due to the unit's substantial 60 kg net weight, cast-iron internal components, and palletised transit requirements, deliveries to residential or non-commercial addresses require a customised tail-lift freight quote. Please contact our friendly commercial sales team prior to placing your order to confirm site access details, doorway clearances (minimum 650 mm clear opening recommended), or to add the matching RB-4-SEN stand to your consignment.

Frequently Asked Questions

What are the operational advantages of flat heavy-duty cast-iron trivets?

Standard raised trivets create separate rings that require chefs to lift heavy pots over barriers, increasing the risk of spills and kitchen burns. The flat cast-iron trivets on the Gasmax RB-4ELPG sit level across the entire 602mm cooktop surface. This allows cooks to slide heavy stockpots, pans, and woks smoothly from a high-heat front burner to a gentle simmer burner without lifting.

How does the flame failure safety system operate on this LPG cooktop?

Each burner is equipped with a thermoelectric safety thermocouple. If a burner flame is accidentally extinguished by kitchen cross-drafts, strong ventilation hood pull, or a liquid boil-over, the thermocouple rapidly cools and automatically shuts off the LPG flow to that specific burner within seconds, preventing hazardous unburnt gas buildup in the kitchen.

Why must the adjustable legs be installed when using this cooktop on a bench?

The supplied adjustable feet raise the chassis by up to 45 mm. This elevation creates the clearance needed to slide out the under-burner drip pans for daily cleaning and provides essential convective airflow underneath the unit to prevent heat conduction from damaging the underlying benchtop surface.

What is the advantage of pairing the RB-4ELPG with the RB-4-SEN stand?

The optional RB-4-SEN stainless steel equipment stand matches the exact 602 mm x 824 mm footprint of the cooktop. It positions the boiling top at standard commercial working height, frees up valuable kitchen preparation benchtops, and includes a heavy-duty lower undershelf for storing pots, pans, and cooking oils.

How do I activate the 4-year warranty coverage?

The Gasmax RB-4ELPG 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.
