La Cornue Installation Requirements
La Cornue Installation Requirements is a common question among La Cornue owners. This guide walks through it step by step with technician-grade detail.
A La Cornue range is heavy, powerful, and often dual-fuel, so installation planning matters. Getting clearances, gas, electrical, flooring, and venting right before delivery prevents costly surprises. This guide outlines the requirements.
Footprint and clearances
Confirm the exact width for your model (from 60cm up to the 180cm Grand Palais) and allow for side and rear clearances to combustibles per the manufacturer’s specifications. Larger ranges like the 150 and 165 need substantial wall space and adequate aisle clearance in front.
Flooring and weight
Hand-built ranges are heavy. Verify the floor can support the weight and that the surface is level. Anti-tip provisions are important — see our leveling and anti-tip guide.
Gas requirements
Gas and dual-fuel models need a properly sized gas line capable of supplying the total BTU load of the burners (front burners up to ~17,000 BTU on natural gas). If your supply is propane (LP), the range must be converted — see our NG to LP conversion guide. A licensed professional should make the gas connection and leak-test it.
Electrical requirements
Dual-fuel and induction configurations need a dedicated, correctly sized electrical circuit. Induction in particular draws high amperage; incorrect wiring is the leading cause of the U400 connection fault. Have a licensed electrician confirm the circuit before the range arrives. See our induction wiring guide.
Hood and ventilation
Plan the hood before installation: it should be at least as wide as the range, with adequate CFM and a short, straight 6-inch duct. Review our hood sizing guide and venting guide.
Delivery and placement
Measure doorways, hallways, and turns to ensure the crated range can reach the kitchen. Professional white-glove delivery is recommended given the weight and value.
Final steps
After placement, the range should be leveled, gas leak-tested, electrically verified, and put through a first-use break-in. See our first-use break-in guide. For full specifications, consult lacornueusa.com, and schedule a professional installation to ensure everything is done safely.
Pre-delivery checklist
The surest way to avoid a stalled installation is to confirm the essentials before the crate arrives:
- Verify the exact model width and clearances, and that the chosen hood is at least as wide as the range.
- Confirm the gas line is sized for the total burner BTU load and converted to LP if your home runs propane.
- Have a licensed electrician confirm the dedicated circuit for dual-fuel or induction before delivery day.
- Measure every doorway, hallway, and turn on the delivery path against the crated dimensions.
- Confirm the floor is structurally adequate and level for the range’s weight.
Why professional installation pays off
Given the weight, value, and dual-utility nature of most La Cornue ranges, white-glove delivery plus licensed gas and electrical work is the right call. A correct install protects your 5-year warranty, prevents the most common faults (a miswired induction circuit causes the U400 error), and ensures the range is leveled and leak-tested from day one. See our induction wiring guide for the electrical detail.
Frequently asked
- Can I install it myself? Placement may be possible with enough help, but gas and high-amperage electrical connections must be done by licensed professionals.
- What if my doorway is too narrow? Plan an alternate path early; the largest models need careful route planning before purchase.
Final commissioning steps
Installation is not finished when the range is in place. After positioning, it should be leveled, the gas connection leak-tested, the electrical supply verified for grounding and correct sizing, and the range put through a first-use break-in to burn off manufacturing residues — see our first-use break-in guide. On electronic and induction models, confirm no fault codes appear at power-up; a U400 at this stage points straight to a wiring issue to fix before regular use. Completing these checks now prevents problems surfacing later mid-meal.
