Flav-R-Cast™ Cooking Grids
Heavy cast or stainless grids evenly distribute conductive heat for the perfect steakhouse sear. The deep inverted
“V design” vaporizes juices right at the grilling surface for great flavour in either position.
Flav-R-Waves™
Made from durable stainless steel, the Flav-R-Waves™ protect the burners and evenly distribute infra-red and convective heat to vaporize juices and maximize flavour.
Dual-Tube™ Burners
Patented Tube in Tube design ensures a balanced flame from front to back, while two rows of flame per burner provide exceptionally even heat distribution from side to side, resulting in unmatched performance.
Thermo-Flow™ Cook Box
The intake air is precisely calibrated to optimize combustion and minimize airflow, resulting in even heating and fuel-efficient grilling whether the
lid is up or down.
iQue Technology
Technology That Takes the Guesswork of Grilling
Mastering the art of smoking, roasting, rotisserie cooking and grilling has never been easier. With iQue, you’re always in control, grilling with confidence and precision.
