4.2 PILOT BURNER
The Pilot Burner (P/N
29700
) is located on the right-front of the Burner Plate. It contains an
ignition cable, the Pilot gas line connected to the bushing, and the Pilot Burner Rod (P/N
66100
), which should be inspected and/or replaced according the schedule in Table 4-1a.
Figure 4-1a shows the location of the Pilot Burner and related components.
Figure 4-1a: Pilot Burner, Main & Pilot Flame Detector Mounting Locations
The Pilot Burner may be hot, therefore care should be exercised to avoid burns. It is easier to
remove the Pilot Burner from the unit after it has cooled to room temperature.
