The best scanner sighting results are obtained when the scanner is aimed so that the scanner
(viewing) center line intersects the burner center line at a slight angle, as shown in Figure 4. The
area of maximum ultraviolet radiation is near the base of the flame envelope. If only one scanner
is used per burner, the intersection should be made so the line of sight or viewing angle can also
see the igniter flame. Consideration must be given to burner air rotation (burners have clockwise
or counterclockwise air rotation). Figure 5 illustrates how scanner location is influenced by the
igniter position and air circulation. Physical obstructions such as air register blades should not
fall within the scanner’s line of sight.
