Bull Prime Liner S4 4 Burner Gas BBQ Stainless Steel 20kW Infrared LPG

The Bull Prime Liner S4 is the four-burner step up from the S3 — more cooking space, more output, same premium German-designed stainless steel build. Four BLADE turbo burners across a 71 x 45cm cooking surface deliver 20 kW of heat, reaching 300°C in around 10 minutes. The BROIL ZONE infrared side burner still hits 800°C for serious searing, and the NIGHT PILOT knobs now add colour indication — blue when off, red when in use — making evening cooking even more intuitive. Designed in collaboration with Austrian engineers and Scandinavian designer Kaare Magnus, backed by a 15-year limited warranty.

Who Is This For?

• Regular outdoor cooks and entertainers who need four burners and a larger cooking surface than the S3 provides
• Those who cook for larger groups regularly and want the extra 10 x 45cm of cooking area that the S4 delivers over the S3
• Anyone who wants colour-indicated NIGHT PILOT controls — blue off, red on — for clear burner status visibility at a glance
• People looking for a long-term premium BBQ investment with a 15-year limited warranty and European design credentials
