How do I Install a Commercial Wolf Range in a House?

Commercial ranges produce additional heat and are less expensive than domestic ranges. Wolf has provided equipment for commercial cooking for more than 70 years. Wolf has been manufacturing commercial ranges since 1938. Commercial ranges must be installed in houses according to the state and local codes or the National Gas Fuel Code ANSI-Z223.1-1988 and NFPA 54: National Fuel Gas Code 2009. They state how the gas piping system will be used, the maximum pressure to be used (125 psi), appliance requirements, including combustion and ventilation, and what is required in the manufacturer's instructions to abide by the codes.

Install a commercial Wolf range in your kitchen
  1. Check the stove for any damage that may have occurred during transportation to your residence. Contact the company that delivered the stove immediately if damage is found.

  2. Install the range in a location that has at least 36 inches of clear space in front of it. Remove any cleaning solutions, solvents, combustible materials and cleaning tools away from the range, and keep them at least 10 inches from the range. Install the range on 3-inch casters on noncombustible floors or 6-inch legs or 5-inch casters on combustible floors, and keep at least two inches of free space behind the range to ensure air circulation.

  3. Open the crate and check to make sure all the pieces are included in the boxes, and assemble the range according to the instructions included with the range, if necessary.

  4. Remove wires from each burner before you install the range.

  5. Locate a 120-volt electrical supply, which is required to operate the Wolf range properly. This must be a three-prong, grounded receptacle to protect against shock hazards. Plug the power cord into the three-prong grounding plug.

  6. Turn all gas shut-off valves to the closed position. Install the included pressure regulator to the gas supply line. Keep the regulator away from the burners, but accessible for servicing.

  7. Connect the range to the gas line using an iron pipe that is at least 3/4-inch. Use 3/4-inch ID or larger if flexible hose is used in the installation. Turn the gas valve back on.

  8. Test the gas line for any leaks using soap suds or a leak-detecting solution. Never test for leaks with fire.

  9. Level the range in its final position on its legs.

  10. Level the oven. Remove the screws holding the oven on the bottom of the range, and pull the oven bottom out. Locate and adjust the four leveling bolts near the burner compartment corners. Reinstall the oven bottom.

  11. Adjust the door spring. Tighten the spring eyebolt nut under the burner box cover until the spring is tight enough to hold the door closed. Turn the nut another four to five full revolutions.

  12. Level the bolts located under the rear of each griddle plate.

  13. Light the oven. Turn off the thermostat, and remove the louver panel. Take off the heat deflector baffle. Push the red button located on the safety valve for at least 30 seconds. Light the pilot through the opening. Adjust the pilot light by the screw located on the pilot valve. Put the heat deflector baffle and louver panel back in place, and turn the thermostat back on to the temperature you want.

  14. Light the oven top, salamander, cheesemelter, fry top and broilers. Turn off the gas to the range. Wait for five minutes before opening the pilot burner and/or carry-over tube. Adjust the valve 1/4 turn counterclockwise. Light the pilot with a match and adjust it until you see a yellow tip on the flame.

  15. Light all standing pilots for the snorkler. Turn on the toggle switch for snorkeler and adjust the flame to blue, then turn on the gas.


  • Install Wolf ranges in well-ventilated areas. Disconnect the range during any system pressure tests. Immediately test for gas leaks if the slightest odor of gas is detected. Improper installation voids the warranty on commercial Wolf ranges. If a commercial Wolf range is installed in your home for noncommercial purposes, the warranty is void. Use only Wolf replacement parts.
