The burner should be mounted on the drum centerline at the same pitch as the drum. Install a structure to support
and position the burners skid. The skid support structure should provide a minimum adjustment of plus or minus
4 along the centerline of the drum or breeching ring. Burner re-positioning may be required for final burner
Position the mini-skid on the support and securely bolt it in place.
Position the burner so that the distance between the heatshield and the breeching ring (or combustion chamber, if
present) is either 5 or 9, dependent on model size. (See figure 3.)
The pilot flame scanner must be aligned to view just above the pilot as it passes through the flame
holder cone. The second scanner (main flame) should be sighted just over the edge of the flame
holder cone, in line with the flame.
Optional Dual Heatshield - Install the two sections of the optional dual heatshield, if applicable, as shown in fig. 4.
