Description
At the top of the Broilmaster B-Series lineup sits the B-Series Deluxe 40-inch built-in gas grill (BSB405) — the most powerful, most feature-complete built-in grill the brand produces. This is a complete outdoor cooking system: five independently controlled cast stainless Bow Tie burners at 70,000 BTUs total across 853 sq in of heavy-duty cooking surface, plus a 15,000 BTU rear infrared rotisserie burner operating as a sixth, separate cooking system at the back of the firebox.
Five independent temperature zones across 40 inches of cooking surface change how you manage a large cook. Rather than compensating for an oversized grill running unevenly at partial load, the BSB405’s five-zone configuration allows precise temperature gradients from one end to the other: high sear heat on zone one, medium-direct on zones two and three, indirect low on zone four, and hold temperature on zone five. A professional kitchen workflow translated to a residential outdoor setting.
Among comparable 40-inch built-in grills, from Fire Magic’s Aurora series to Lynx’s professional line, the BSB405’s cast Bow Tie burners, five-zone configuration, and American manufacturing heritage represent a formidable value proposition. The integrated hood thermometer is a practical detail that many competitors at this price omit; it matters when you’re running a 40-inch grill at multiple temperature zones simultaneously.
Key Features:Â
- Five Cast Stainless Bow Tie Burners (70,000 BTUs Combined): Five independently controlled zones across the full 40-inch surface, more granular temperature management than any four-burner configuration can provide. The Bow Tie geometry ensures even distribution across every zone at any output level.
- 15,000 BTU Rear Infrared Rotisserie Burner: Higher-output rear infrared burner (15,000 BTU vs 14,000 BTU on the 32-inch model) handles the larger rotisserie loads the 40-inch platform supports — full-size turkeys, double-bird setups, oversized prime ribs.
- 853 Sq In Total Cooking Area:Â Large-event cooking capacity: 30+ burgers, multiple racks of ribs, or a full multi-protein spread handled in a single cook session with room to stage and hold.
- 5/16-Inch Heavy-Duty Cooking Grates:Â Thick-gauge grates retain and radiate stored heat, producing deeper sear marks and more consistent carryover cooking than thinner commercial-grade grates.
- Removable Heat Zone Dividers — Five Independent Zones: Physical zone separation across five independently controlled burners creates precision temperature management across the full 40-inch surface, a meaningful operational advantage when cooking for large groups simultaneously.
- Welded & Polished Double-Lined Hood with Hood Thermometer:Â Precise indirect cooking and finish-roasting under the hood; the integrated thermometer tells you exactly what temperature your food is finishing at without lifting the lid.
- Interior Work Lights + LED Control Panel + Flame Thrower Ignition:Â Professional-grade usability features for serious outdoor cooking at any hour or in any conditions.
