The Prime Liner S4 Gas Barbecue by Bull builds on the strengths of the S3, offering increased capacity and an additional burner for greater flexibility. With its durable stainless steel construction and thoughtful design, it’s made for those who regularly cook outdoors and need both space and performance.
High Heat, Fast Results
Powered by four patented BLADE™ turbo burners, the S4 delivers strong, even heat across a larger cooking area, reaching up to 300°C in just ten minutes. This makes it ideal for everything from fast searing to controlled, even grilling.
The BROIL ZONE™ infrared side burner reaches up to 800°C, perfect for sealing steaks or preparing sides alongside your main dishes.
Built for Regular Use
The S4 is designed with durability at its core. Its 8mm stainless steel cooking grates provide excellent heat retention and long-term reliability, while the stainless steel body offers a robust, weather-resistant finish.
A double-insulated hood, combined with die-cast aluminium side panels, helps retain heat within the cooking chamber, supporting consistent and balanced results across a wide range of dishes.
Simple, Reliable Operation
The PRIME FIRE™ independent piezo ignition system ensures reliable lighting, supported by cross-ignition for added convenience. NIGHT PILOT™ backlit control knobs clearly indicate burner status, glowing blue when off and red when in use—making evening cooking straightforward and safe.
Side shelves offer practical space for preparation, while the integrated hanging rail keeps utensils close at hand. Four swivel casters with locking brakes allow for easy movement and stable positioning.
Designed for Outdoor Living
With its clean lines and full stainless steel construction, the Prime Liner S4 brings a refined, contemporary look to any outdoor space. Developed in collaboration with Austrian engineers and Scandinavian designer Kaare Magnus, it balances performance with a considered, understated design.
