are specifi ed relative to the main
air connection at 12 oclock and should be listed for
pilot,
gas, fl ame supervison and atomizing air in that order.
‡
Good practice dictates that neither the pilot nor the fl ame detector be below the centerline of a horizontally-mounted burner.
ORDER MUST SPECIFY
: (1) Burner designation (such as 6821-16-54); (2) Arrangement designation for pilot, gas connection, fl ame safety and
atomizing air connection positions in that order such as 6821-16-54, arrangement 3a1E (for the arrangement shown above).
