  • Thermador Masterpiece Gas Cooktops may also be installed above a Thermador Warming Drawer to create a convenient cooking center.


  • We strongly recommend the installation of a Thermador Ventilation System with this gas cooktop.
  • Seal the surfaces of the cutout to make them heat resistant.
  • This prevents the surfaces from expanding as a result of humidity.
  • Solid surface counter-tops often require special installation.
  • For example, heat reflective tape or rounded corners may be necessary.

Natural Gas or LP

  • Thermador Masterpiece Gas Cooktops are shipped by the factory to operate on natural gas.
  • They must be converted for use with propane.
  • Verify the type of gas being used at the installation site matches the type of gas used by the appliance.
  • If the location/job site requires conversion from natural gas to propane (LP), order SNLPKITF.
  • Field conversion must be done by qualified service personnel only.
