Gasmax JUS-TRH40E Lava Rock Gas Grill 405mm | 28Mj Commercial Natural Gas

[GASMAX_MSG]

The Gasmax JUS-TRH40E Commercial Benchtop Natural Gas Lava Rock Grill (405mm Wide) is a high-performance open-flame charbroiler engineered specifically for Australian steakhouses, burger bars, cafes, pub bistros, and boutique restaurant cooklines operating on reticulated mains Natural Gas. Measuring 405 mm Wide x 650 mm Deep x 475 mm High and weighing a solid 45 kg, this 400mm-format countertop chargrill harnesses authentic volcanic lava rocks to distribute intense radiant heat across steaks, burgers, chicken fillets, and chargrilled vegetables. Powered by a heavy-duty commercial burner delivering an energetic 28 Mj/h thermal consumption, the JUS-TRH40E captures rendered juices in the porous lava stones to vaporise them into authentic wood-smoke barbecue aroma while leaving clean, defined sear lines. Constructed from commercial food-grade stainless steel with push-button auto ignition, certified thermoelectric flame failure shut-off safety protection, a removable slide-out stainless steel drip catchment tray, and an industry-standard 1/2" rear gas connection, this unit offers high searing efficiency within a compact benchtop profile.

Why Australian commercial kitchens, steakhouses, and burger bars choose the Gasmax JUS-TRH40E:

• Authentic volcanic lava rock radiant system — high-density natural volcanic stones absorb, store, and disperse uniform radiant heat, vaporising dripping oils and marinades to infuse grilled proteins with rich, authentic chargrill flavour.

• High-intensity 28 Mj/h commercial burner — robust burner delivers intense heat across the 405mm grilling bed, ensuring fast searing and rapid thermal recovery during high-turnover peak service hours.

• Automatic piezo ignition system — dependable push-button auto ignition provides instant lighting without relying on handheld matches or open taper lighters.

• Certified flame failure safety shut-off — thermoelectric safety thermocouple continuously monitors the flame, automatically isolating the Natural Gas supply within seconds if the flame is accidentally extinguished by kitchen draughts or boil-overs.

• Compact 405mm benchtop footprint — designed to integrate neatly into space-restricted commercial cooklines, open display kitchens, and modular pass counters without sacrificing professional charbroiling capacity.

• Full food-grade stainless steel construction — heavy-gauge stainless steel front fascia, side panels, and internal body frame resist kitchen grease, corrosive salts, and high radiant heat while enabling fast end-of-shift washdowns.

• Removable slide-out stainless steel drip tray — full-width bottom collection drawer catches excess grease runoff and charred food crumbs, sliding out smoothly for safe mid-shift emptying and sanitising.

• Modular stand compatibility (JUS400E) — purpose-built to sit cleanly on standard commercial benchtops or mount securely onto the optional Gasmax JUS400E stainless steel stand (sold separately) to create an ergonomic freestanding station with an undershelf.

• 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.

Technical Specifications

Daily Care, Maintenance & End-of-Shift Sanitisation

To preserve thermal radiant efficiency, prevent grease fires, and ensure sanitary kitchen operations:

1. End-of-Service Grate Scrubbing: At the close of trade while the grill is still warm, scrub the heavy-duty cooking grates using a commercial wire grill brush to strip away carbonised fats and marinade crust. Lightly wipe the grates with a cloth dampened with food-grade vegetable oil to season the metal and prevent overnight surface oxidisation.

2. Lava Rock Maintenance & Inversion: Volcanic stones absorb fats and oils during service. Once or twice a week, flip the lava rocks over and run the burner on high for 15 to 20 minutes to burn off accumulated grease deposits into white ash. Replace degraded or crumbling lava stones periodically to maintain even heat radiation and prevent excessive fat flare-ups.

3. Drip Catchment Drawer Clearing: Slide out the bottom stainless steel grease tray daily. Empty collected rendered fats, oils, and ash into an approved waste container, then wash the drawer in a commercial pot-wash sink with warm water and an approved commercial degreaser.

4. Stainless Steel Body Care: Wipe down the front control panel, outer casing, and side splash walls daily using a soft microfibre cloth dampened with warm soapy water, wiping in the direction of the brushed metal grain. Avoid splashing cold water directly onto hot cast grates or burners, as thermal shock can fracture metal components.

5. Burner Port & Aeration Inspection: Regularly inspect the burner ports and air shutter collars beneath the rock bed. Clear any ash, marinade drips, or grease clogs using a soft wire probe or nylon brush to maintain clean blue-flame combustion and avoid carbon monoxide build-up.

Gas Installation, Ventilation & Commissioning Notice

The Gasmax JUS-TRH40E is a commercial gas cooking appliance requiring certified trade commissioning:

1. Mandatory Licensed Gas Fitter Commissioning: The unit must be installed, pressure-tested, and commissioned by an authorised, licensed gas technician 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 & Pressure: Calibrated for reticulated Natural Gas and fitted with a 1/2" rear gas inlet. Ensure incoming pipework and upstream regulators deliver rated operating gas pressure without pressure dips when other line appliances are running at maximum capacity.

3. Exhaust Extraction Requirements: Generating substantial radiant heat, grease-laden smoke, 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 Clearances & Stand Mounting: Install on a heat-resistant commercial stainless steel workbench or mount directly onto the matching Gasmax JUS400E 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 dock facilities. Due to the unit's 45 kg net weight and palletised transit format, 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 delivery logistics, site access details, or to add the matching JUS400E equipment stand to your consignment.

Frequently Asked Questions

What are the cooking advantages of a lava rock grill over standard cast-iron radiants?

Volcanic lava rocks mimic traditional charcoal embers. Because the natural porous rock absorbs heat, it creates an exceptionally even thermal bed that eliminates extreme hot spots across the cooking surface. When fats and juices drip onto the super-heated stones, they instantly vaporise, sending flavour-packed smoke back into steaks, burgers, and skewers for an authentic open-grill taste without the mess of lump charcoal.

How do I maintain and clean the lava rocks?

Lava rocks are self-cleaning when inverted. At the end of a busy week, simply turn the rocks over so the grease-coated side faces down toward the burner. Turn the grill on high for 15 to 20 minutes; the intense direct flame will incinerate trapped oils into dry white ash, which can then be brushed away once cooled.

Can the JUS-TRH40E be mounted on an equipment stand?

Yes. Gasmax manufactures the dedicated JUS400E stainless steel equipment stand engineered to match the exact 405 mm x 650 mm base footprint of this grill. The stand positions the grill at an ergonomic commercial working height and includes a sturdy lower undershelf for storing utensils, basting pans, and replacement rock packs.

Why is commissioning by an authorised technician mandatory?

Commercial gas appliances operate under strict Australian safety standards (AS/NZS 5601). A licensed gas technician ensures correct operating gas pressure, performs mandatory leak tests, calibrates primary air shutters for clean combustion, and issues an official compliance certificate, which is required to activate the manufacturer's warranty.

How do I activate the 4-year warranty coverage?

The Gasmax JUS-TRH40E 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.
