Product Highlights
Commercial-Grade 304 Stainless Steel Construction
The burners, cooking grates, flame tamers, and exterior are all made from 304 stainless steel — the grade used in commercial kitchens — built to resist corrosion and handle years of outdoor use.
Push and Turn Flame-Thrower Ignition
The push-and-turn flame-thrower ignition system is designed for a reliable start. A backup flash tube ignition with crossover channels lights the burners if the primary ignition ever fails.
Heat Zone Separators for Cooking Versatility
Independently controlled burners with heat zone separators create distinct cooking zones, so you can sear at high heat on one side while slow-cooking or warming on another, all at the same time.
Removable Warming Rack
The 141 sq. in. removable warming rack keeps bread, sides, and finished items at serving temperature while you continue grilling on the 417 sq. in. main surface.
Analog Thermometer Included
A built-in analog thermometer gives you an at-a-glance read on grill temperature, so you can manage heat without lifting the lid.

Frequently Asked Questions
What are the cutout dimensions for installation?
The required cutout dimensions are 23 1/4" wide x 21 1/4" deep x 8 1/2" high. Measure your outdoor kitchen opening carefully before ordering to confirm fit.
Can this grill be converted to natural gas?
The BLZ-3LBM-LP is configured for propane. A natural gas conversion kit may be available — contact Blaze or your dealer for options and instructions before attempting any conversion.
What does the lifetime residential warranty cover?
Blaze's lifetime residential warranty covers the grill for as long as you own it for residential use. A 3-year multi-user commercial warranty applies to settings such as apartment complexes and condominiums. Refer to Blaze's warranty documentation for full terms and exclusions.
How do the heat zone separators work?
Heat zone separators sit between the burners to reduce heat transfer between cooking zones. You can run one burner on high for searing while keeping another on low for slow cooking or warming — all on the same grill, at the same time.
What happens if the primary ignition fails?
The BLZ-3LBM-LP includes a backup flash tube ignition system with crossover channels. If the primary push-and-turn ignition fails, the flash tubes light the burners so you can continue grilling.
The Blaze LBM 25" is built for homeowners who want a grill that performs at a commercial level, fits a built-in outdoor kitchen, and holds up for the long term.
