Pilot Burner Ordering Information Pilot burners can be ordered with or without an inlet fitting that controls the flow of gas to the pilot burner. Figure 12 shows example part numbers for ordering pilot burners with or without an inlet fitting.

PAGE 11
Y90 Inlet Fittings The Y90 inlet fitting controls the flow of gas to a pilot burner. The orifice hole size and counterbore/coining, along with the applied gas pressure, determine flame size and characteristics. Counterbore Inlet Tip Pilot burner inlet fittings consist of an inlet tip (containing the orifice holes) and a threaded inlet body allowing connection of the pilot line. The orifice holes are used to direct and control the flow of gas to a pilot burner.
