This model carries the model number BLZ-4LBM-LP. The fuel source is the primary distinction between these two grills. One requires permanent installation, while the other offers portable fuel options. You must choose based on your existing infrastructure or preference.
Heat Output
Both grills deliver identical heating performance. Each model features four stainless steel tube burners. Each burner produces 14,000 BTUs.

Build Material
