The Blichmann TopTier Burner fits any manufacturer's kettles or kegs up to 21" in diameter and up to 30 gallon volume. 72,000 BTU/hr of power! Can be used in the Blichmann patented TopTier™ Modular Brewing Stand or on its own. When you're ready to upgrade to a tiered system, this burner will just bolt right into the TopTier Stand! Optional leg extensions make it easy to drain cooled wort directly into your carboy. Heavy-gauge, stainless-steel burner frame never rusts, and there are no nasty paint-burning fumes. Includes regulator.
