Determine If Wolf Gas Product Is Natural Gas or Liquid Propane


  • How to tell if a unit is built for natural gas (NG) or liquid propane (LP) gas

The serial tag and rating plate contain the gas type information, either natural gas (NG or NAT) or liquid propane (LP). See Wolf Serial Tag Locations for location information.

  • A unit that has been converted can be changed back to the original gas type if needed.
