The Bull Prime Liner S4 Gas Barbecue is a premium four-burner barbecue designed for outdoor cooks who want generous grilling capacity, powerful heat and high-quality stainless steel construction. Delivering a maximum output of 20kW, the S4 combines four patented BLADE Turbo Burners with an independent high-temperature infrared side burner, giving you the flexibility to grill, roast, sear and cook indirectly across multiple temperature zones.
Four BLADE Turbo Burners provide consistent heat across the spacious 71 x 45cm main cooking area, making the S4 particularly well suited to larger families and outdoor entertaining. Capable of reaching approximately 300°C in around 10 minutes, the barbecue offers fast preheating alongside heavy-duty 8mm stainless steel cooking grates designed for excellent heat retention, durability and impressive grill marks.
For serious high-temperature cooking, the S4 features Bull's dedicated BROIL ZONE infrared side burner. Capable of reaching temperatures of up to 800°C, the independent burner delivers the intense direct heat required for steakhouse-style searing while leaving all four main burners available for grilling, roasting or preparing other dishes.
Operating the barbecue is straightforward thanks to the PRIME FIRE independent piezo ignition system with cross-ignition across the four main burners. Bull's NIGHT PILOT colour-indicated controls provide clear burner status at a glance, glowing blue when switched off and red when in use. A double-insulated hood also helps maintain stable temperatures when cooking with the lid closed.
Premium stainless steel construction distinguishes the S4 from the matte-coated G4, providing a smart professional appearance for contemporary patios and outdoor kitchens. Die-cast aluminium side panels create useful preparation space, while an integrated utensil hanging rail keeps essential barbecue tools within easy reach. Four swivel castors with locking brakes allow the barbecue to be repositioned and then secured during cooking.
