CASTA 4-Burner Gas Hob for Professional Kitchens

A gas hob built for the demands of a professional kitchen, where every burner must deliver instant, precise heat. The CASTA LQ/CUG4BB.4G supplies four high-output gas burners, each firing beneath a heavy-duty cast-iron grate. Gas hobs of this type work by mixing natural or propane gas with air at the burner head, where a spark or pilot flame ignites the mixture. The resulting flame transfers heat directly to the base of the pan, giving the chef immediate control over temperature and rapid response to changes in demand. Because the heat is radiant and convective, it spreads evenly across the pan surface, reducing hot spots and allowing consistent cooking across large batches.

The sequence of use is straightforward. The hob is installed on a worktop and connected to the gas supply. Each burner is lit manually by pressing the control knob, which opens the gas valve and activates the pilot flame. Once the thermocouple safety system detects a stable flame, the knob can be turned to adjust the size of the main burner flame, from a gentle simmer to full power. Spill trays beneath the grates catch any overflow, preventing grease and liquids from reaching the work surface. After service, the trays slide out for emptying and cleaning, while the grates lift off to expose the burner heads for inspection and wipe-down.

The hob is constructed from 2 mm thick AISI 304 stainless steel, formed into a seamless work surface with raised edges to contain spills. The top plate is finished in a Scotch-Brite satin texture, which resists scratches and hides minor marks from daily use. Beneath the surface, the hob is fully enclosed, with no gaps between the burners, grates and spill trays, sealing the interior against grease and moisture. The grates themselves are made from black enamelled cast iron, chosen for its ability to withstand high temperatures and repeated thermal shock without warping or discolouring. Each burner is porcelain-enamelled cast iron, designed to resist corrosion from acidic or alkaline cleaning agents and maintain a bright, clean appearance.

Controls are mechanical knobs, one for each burner, with a cool-touch coating that stays safe to handle even after prolonged use. The knobs incorporate a flame-failure safety device: if the flame goes out, the thermocouple cools and shuts off the gas supply automatically, preventing unburned gas from accumulating. The hob stands on adjustable feet, allowing it to be levelled on uneven floors and raised for cleaning beneath.

The power rating of 4 x 7.4 kW indicates the load each burner places on the gas supply; together they require a dedicated gas line capable of delivering the total flow without pressure drop. The footprint of 800 mm by 900 mm fits standard worktop depths and allows two chefs to work side by side without crowding. The low height of 275 mm keeps the cooking surface at a comfortable working level while leaving room beneath for gas pipework and spill trays.

Cleaning follows from the materials and construction. The stainless steel surface can be wiped down with a damp cloth and mild detergent; abrasive pads should be avoided to preserve the satin finish. The grates and spill trays are removable and dishwasher-safe, though hand-washing is recommended to extend the enamel life. Burner heads lift off for access, and the sealed underside prevents grease from collecting inside the unit. The cool-touch knobs and control panel can be cleaned with a damp cloth but should not be submerged.

The hob is designed for installation on a worktop and is not supplied with a cupboard or shelf beneath. It is a single-unit appliance with no variants or optional extras listed in the catalogue.
