The Broil King Signet 390 is the fully-loaded version of one of Broil King's most enduringly popular gas grills — the Signet series. Adding a powerful side burner, rear rotisserie burner, and premium rotisserie kit to the already impressive Signet 320 platform, the 390 delivers a genuinely comprehensive outdoor cooking experience that covers every cooking technique from high-heat searing to slow rotisserie roasting.

Three stainless steel Dual-Tube™ burners deliver 40,000 BTU across a 400 sq. in. primary cooking surface, with a total cooking area of 635 sq. in. including the porcelain-coated warming rack. The patented tube-in-tube, side-ported burner design provides two rows of flame per burner for class-leading heat distribution. The Therma-Cast™ die-cast aluminium oven provides exceptional heat retention and durability, backed by a limited lifetime warranty on the cookbox.

A 10,000 BTU commercial-grade side burner on the left-hand shelf gives you a dedicated cooking zone for pots, pans, sauces, and side dishes — running simultaneously with the main grill without any interference. The 15,000 BTU rear rotisserie burner, combined with the included premium rotisserie kit, allows you to slow-roast whole chickens, joints, and larger cuts with continuous self-basting rotation.

The stainless steel Flav-R-Wave™ cooking system protects the burners and vaporises drippings to infuse food with BBQ flavour. Reversible heavy-duty cast iron Flav-R-Cast™ cooking grids, Linear-Flow™ valves with 180° Sensi-Touch™ control, Sure-Lite™ electronic ignition, and a Deluxe Accu-Temp™ thermometer complete the feature set. Stainless steel drop-down side shelves and an enclosed cabinet base with stainless steel doors round off an impressive package.

Really impressed with the build quality. We've had cheaper sets before that didn't last a season
