Gas conversion on a Legacy Duel Fuel (DF) Range varies based on the unit's serial number.

  • Prior to serial (PTS) number 17000000, gas conversion for Legacy DF ranges is not possible.
    • Only high altitude kits for LP units are available for units PTS 17000000.
    • Use part number 805725.
  • The burner design was different and made field conversion impossible to make sure of proper unit operation.
  • LP units above 8,600' use a high altitude kit.
  • For natural gas units above 10,250', conversion is only possible on units starting with serial number 18180000.
  • It is unusual for natural gas units to require a high altitude conversion. LP is usually the only option at such an altitude.
  • The Btu output does not change after a conversion, except for the griddle, which is 2,000 Btu less when converted to LP gas.
  • Starting with serial number 17000000, convert back to the original gas type by ordering the appropriate conversion kit.

Starting with serial number 17000000, Legacy DF ranges can be converted from natural gas (NG) to liquid propane (LP) gas or from LP to NG using the following kits:
