SHUTTER SETTINGS

Kettle Size/Gas Type		Natural	Propane
20	Gallon (80,000 BTU/HR)	1.5	2.0
30/40 Gallon (100,000 BTU/HR)		1.5	2.0
60	Gallon (120,000 BTU/HR)	2.0	3.0

Shutter setting is on the fan intake. Adjust the shutter per the table above by loosening the screw on the shutter closest to the stamped numbers and turning the shuttle disc until the screw points to the correct setting. Tighten screw when adjustment is complete. Figure 1 below shows a shutter setting of 2.0. Look at the flame through the plastic window in the rear of the burner. It should be mostly blue with slight bits of orange flame on natural gas. On propane, flame will be more orange in color. Using a portable gas analyzer, shutter settings can be adjusted to yield between 5.0-8.0 CO2. Air free CO should read below 100ppm. Once the burner is set up and operating properly, secure all wires and replace all covers.
