Question about Le Creuset Signature

Le Creuset instruction manual:
Le Creuset cast iron cookware can be used on ALL heat sources: Gas, Electric, Coil, Glass Ceramic and Induction hobs and in all ovens, whether they are gas, oil, coal or wood fired.
Gas flames must always be adapted to the base of the pan and NEVER burn beyond the sides of the pan.
Long handles should be positioned safely, i.e. they should not protrude over the front of the cooker or go across the heat sources.
Oven use:
Products with black phenolic lid knobs (type A) are designed to be used in the oven at temperatures of 200 C or level 6 for gas-fired ovens.
Products with black phenolic lid knobs (type B) are designed to be used in the oven at temperatures of 250 C or level 9 in gas-fired ovens
Products with cast iron handles or stainless steel lid knobs can be used in the oven at any honing temperature.

According to research, this should not be used over fire (outdoor).

The pot can also be used over an open fire. However, it should not be placed in the middle of the embers. Too high temperatures will damage the enamel.
