Broilmaster B-Series Deluxe 40-Inch – Built-In Gas Grill with Rear Infrared Burner
A 304 stainless steel built-in gas grill with 70,000 BTUs and 853 in² of cooking capacity for serious entertaining.
70,000 BTUs across five cast stainless steel burners puts fast, consistent heat across 853 in² of total cooking area — 648 in² of main grate plus a 205 in² warming rack — giving you real room to grill for a crowd. The 15,000 BTU rear infrared burner unlocks true rotisserie roasting for crisp skin and juicy centers, while Heat Zone Dividers let you sear hard on one side and hold gently on the other. Flare Control Vaporizers turn drippings into flavor instead of flare-ups. Built entirely from 304 stainless steel with a welded double-lined lid, this 40-inch grill brings a commanding, professional presence to any built-in island. Illuminated knobs and interior lighting keep nighttime grilling just as precise, and it's made in the USA.

Deep Dive — Burner System & Heat Management►
Premium 304 Stainless Steel Construction & Design
From the cookbox to the cooking grids, the Broilmaster B-Series Deluxe 40-Inch is engineered from 304 stainless steel for superior corrosion resistance and long-term durability in exposed outdoor environments. The welded and polished double-lined lid helps lock in heat while maintaining a refined, low-profile silhouette in your island.
Five Cast Stainless Burners & Rear Infrared Rotisserie Power
Five 14,000 BTU cast stainless steel burners deliver a combined 70,000 BTUs of grilling power for fast preheats and consistent searing across the main grate. At the back, the dedicated 15,000 BTU rear infrared burner is designed for rotisserie cooking, creating intense radiant heat that crisps the exterior while preserving moisture inside.
Heat Zone Dividers, Flare Control & Clean Operation
Integrated Heat Zone Dividers provide distinct cooking zones so you can run one side hot for intense searing while keeping the other at a lower temperature for gentle grilling or holding. Broilmaster's Flare Control Vaporizers move drippings away from the burners, channeling them into the slide-out drip tray.
Illuminated Controls, Interior Lighting & Reliable Ignition
Illuminated, ergonomic control knobs and internal grill lighting keep your cooking surface visible and easy to manage long after sunset. The reliable Flame Thrower ignition system provides fast, consistent starts without fumbling with matches.
Who It's For — The Deck & Den Take►
This one's for the host who's regularly cooking for a crowd and needs the extra grate real estate the 32-inch model doesn't offer. Five burners and 853 in² gives you genuine room to run multiple proteins at once without crowding the grate. If you're cooking for a small household, the 32-inch version will save you money without sacrificing much. This is standard 304 stainless — if you're right on the coast or near a saltwater pool, look at Broilmaster's 316 marine-grade line instead. One thing worth knowing: this is a built-in grill head only, so confirm your cutout dimensions before it arrives.
- Hosts who regularly cook for large groups and need serious main-grate capacity
- Homeowners building a commanding built-in island centerpiece
- Buyers in standard inland climates who don't need marine-grade corrosion protection
- Cooks who want true rotisserie capability alongside standard grilling (rotisserie kit sold separately)
