Product Highlights
Direct Natural Gas Convenience
The BLZ-3LBM-NG connects directly to your home’s natural gas line, eliminating the need to monitor and replace propane tanks. It is the right choice for built-in outdoor kitchens with an existing gas line or planned gas infrastructure.
Commercial-Grade 304 Stainless Steel Throughout
Burners, cooking grates, flame tamers, and the exterior are all 304 stainless steel — the same grade used in commercial kitchens — built to resist corrosion and withstand years of outdoor use.
Push & Turn Flame-Thrower Ignition
The push-and-turn flame-thrower ignition provides a quick, reliable start every time. A backup flash tube ignition system with crossover channels ensures the burners light even if the primary ignition fails.
Heat Zone Separators for Multi-Zone Cooking
Independent burner control combined with heat zone separators lets you run distinct cooking temperatures side by side — sear on high, slow-cook on low, and warm on the rack simultaneously.
Removable Warming Rack & Analog Thermometer
The 141 sq. in. removable warming rack keeps sides and finished items at serving temperature while you grill. A built-in analog thermometer provides an at-a-glance temperature read without lifting the lid.

Frequently Asked Questions
What is the difference between the BLZ-3LBM-NG and the BLZ-3LBM-LP?
The BLZ-3LBM-NG runs on natural gas and connects directly to your home’s gas line. The BLZ-3LBM-LP runs on propane from a tank. All other features — BTU output, cooking area, construction, and warranty — are the same. Choose based on your fuel source and outdoor kitchen setup.
Do I need a professional to install the natural gas connection?
Yes. Natural gas line connections must be installed by a licensed professional in accordance with local building codes and the manufacturer’s installation guidelines. Do not attempt a DIY gas line connection.
What are the cutout dimensions for installation?
The required cutout is 23 1/4" wide x 21 1/4" deep x 8 1/2" high. Measure your outdoor kitchen opening carefully before placing your order.
What does the lifetime residential warranty cover?
Blaze’s lifetime residential warranty covers the grill for as long as you own it in a residential setting. A separate 3-year multi-user commercial warranty applies to settings such as apartment complexes and condominiums. Refer to Blaze’s warranty documentation for complete terms and exclusions.
What happens if the primary ignition fails?
The BLZ-3LBM-NG includes a backup flash tube ignition system with crossover channels. If the push-and-turn ignition fails, the flash tubes ignite the burners so grilling can continue without interruption.
The Blaze LBM 25" Natural Gas Grill is the right choice for outdoor kitchens with a natural gas connection — reliable, high-output, and built to last. If you are ready to stop managing propane tanks, this is the grill to build around.
