A La Cornue range set up for natural gas will not run correctly on propane without conversion, and a range moving to a meaningfully higher altitude may need adjustment for the thinner air as well. Both are real, well-understood adjustments — but both go far more smoothly when planned before a move than diagnosed afterward as “the range doesn’t seem right since we moved it.”
Why Waiting Costs More Than Planning Ahead
Because a number of La Cornue parts are ordered specifically against a given range’s exact model and configuration rather than pulled from generic stock, and because parts frequently ship from France, discovering after a move that a range needs a fuel-specific part can mean weeks without a working range while the correct piece is ordered and shipped. Confirming what your specific range needs, and arranging both the part and the appointment before the move happens, avoids that gap entirely.
What to Confirm Before You Move
Your range’s current fuel type, its exact model and configuration, and the fuel type or altitude range at the destination are the basic facts a technician needs to identify what conversion parts, if any, are required. Having your range’s documentation or model information ready when you first reach out saves a round of back-and-forth before the actual planning can start.
Why This Is Never a Self-Service Job
Regardless of how much is planned in advance, the physical work of a fuel conversion — replacing orifices, adjusting or replacing a regulator, and confirming the range performs correctly on the new fuel afterward — is technician-only, the same as any other gas connection or conversion on the range. Planning ahead changes how long the process takes; it does not change who should be doing the physical work.
What Happens If a Range Arrives Unconverted
A range that has not been converted for its new fuel, or not adjusted for a significant change in altitude, will very often seem to run weak or perform inconsistently once it is reconnected — a pattern that is easy to mistake for a part having failed in transit, when the range itself may be working exactly as it should on the wrong setup for its new location.
Moving Timelines Are Worth Building In Early
Because a kitchen move or renovation timeline is usually set well in advance, reaching out about a fuel or altitude change as soon as a move date is known — rather than the week before — gives the widest possible window for parts that may need to travel from France. It also gives you time to have your exact model and configuration confirmed in writing, rather than trying to identify it under time pressure the week the range is scheduled to be reconnected.
If you are planning a move that changes your range’s fuel type or altitude, a La Cornue range repair visit can confirm what your specific range needs before the move happens, not after.
