GR Series Gas Range Gas Conversion


  • Convert the GR Series Gas Range from natural gas (NG) to propane (LP) or from LP to NG
  • What is the part number for the high altitude conversion kit for the GR Series Gas Range?
  • Gas conversion kit, part number 821202, 821203, 821204, instruction sheet 821273
  • Does the Btu output change if the gas type is converted?


When possible, purchase products made for the gas type they are connected to. Gas conversion on a GR Series Gas Range is possible with the use of a conversion kit.

  • LP GR Series Gas Ranges do not require conversion at high altitudes.
  • The conversion does not change the total Btu output of the unit.
  • If a gas product is converted to the other type of gas, a sticker is placed near the original serial tag and rating plate to indicate the gas type change.
  • A unit that has been converted can be changed back to the original gas type if needed.
  • Griddle orifice (57) can also be stamped 1.15 (mm).
  • The High Altitude Kit is for units installed above 8,600' (2621 m) in altitude.
