Vented and vent-free gas log burner systems and companion log sets from Grand Canyon Gas Logs — 2-Burner and 3-Burner traditional systems, Bedrock contemporary linear burners, the Lava Burner with GlowFire™ log technology, and Vulcan vent-free burners. Filter by fuel type, vented vs. vent-free, and log species below.

Choosing 2-Burner vs. 3-Burner

Both are traditional vented systems using the same log species — the difference is heat output and size range. From 24" up, the extra burner tube in the 3-Burner line delivers meaningfully more heat and more even flame coverage across the same log bed, at a higher price point.

Size 2-Burner BTU (NG) 3-Burner BTU (NG) Difference
18″ 52,000 46,000 2-Burner slightly higher
24″ 64,000 74,000 3-Burner +16%
30″ 76,000 102,000 3-Burner +34%
36″ 81,000 111,000 3-Burner +37%
42″ 86,000 120,000 3-Burner +40%

2-Burner also extends up to 48"/60" for larger openings; 3-Burner tops out at 42".
