Signet 390

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.
