For Dicro-Clean 909 cleaning solutions or hot water rinse tanks, you don't need as much burner capacity as our bluing tank pipe burner delivers. So, to save you gas, and some setup costs, we had these special Hot Water Cleaning Tank Burners designed. They have one row of specially sized and positioned holes in a " pipe. Includes a mixer head and the gas cock with either LP or Natural Gas orifice. (Don't use on the bluing tank; they won't make enough heat.) Mfg: Brownells SPECS: 42" (106.7cm) overall length. Weighs 4" lbs. (2.0kg) " (6.3mm) NPT pipe thread on gas cock. Requires 11" (27.9cm) w.c. gas pressure for LP; 4"-6" w.c. for Natural Gas. 25,600 BTU.
