# La Cornue propane conversion service

### About converting one of these to propane, properly

La Cornue publishes a conversion procedure and a defined parts set for the CornuFé 90 and 110, and specifies fuel at order time on a Château. What we see is ranges converted with universal kits, ranges converted in part — the front burners done and the plaque burner forgotten — and ranges moved from a propane house to a natural-gas one with nothing changed at all. All three give yellow flames, soot and burners that will not hold a simmer. Doing it properly means the maker's own orifices, every burner and both oven burners set, a leak check, and a written record of the fuel the range is now on.

What this involves

The maker's own orifice set, not a universal kit

Every burner and both ovens set and verified, not just the fronts

Written record of what the range is now set for

Establish what it is set for now

Orifices, regulator, air shutters. A half-converted range is common and dangerous to assume about.

Fit the maker's own parts

The published orifice set and regulator for that model. A universal kit is where yellow flames and soot come from.

Set every burner

Fronts, rears, power burner, the plaque burner, the grill. Missing the ones nobody uses is how this comes back.

Both ovens and the broiler

The oven burners are converted too, and their flame is the one nobody sees.

Leak check, then label it

Every joint tested, and the range left with a written record of the fuel it is now set for.

### The range came with a conversion kit in the box. Can I fit it?

The CornuFé models do ship with one and the procedure is published. Whether you fit it is a question about gas work rather than difficulty: every orifice changed is a joint that must be leak-tested, and a burner set by eye is the yellow-flame page. If you are qualified for gas work, the documentation is there. If not, this is the wrong job to learn on.

### How do I know if mine was converted properly?

Look at every burner, including the ones you never use. Blue flames with a defined inner cone, no soot on a pan bottom, and a low flame that holds. If any burner runs yellow — or if the range has changed house and nobody mentioned fuel — it is worth a diagnostic.
