Before installing any oil burner, become fully aware of the manufacturer's recommended settings. Read the instructions. Install the burner with the proper insertion depth and pipe and wire according to the manufacturer's recommendations. Be sure to follow all codes and laws that exist in your locality. In the event your area does not have local codes for oil burning equipment, use the NAFTA (North American Free Trade Agreement) recommended codes.
Check the "Z" dimension on all fixed-head burners. This can easily be done using the gauge supplied by the manufacturer. On adjustable-head burners, you should also check the zero setting to ensure that the tube is matched to the drawer assembly and adjust if necessary.
