This barbecue can only be used with blue gas cartridges.

Thank you very much. I use the CV 470 Plus 450 g gas cartridge, I'm not a "permanent griller", only occasionally, so it's ideal.
I have seen that there is an adapter for a large cylinder, but I don't know whether the model is designed for continuous operation. I can't say. Salutations

However, there is also a model (without CV) of this barbecue where you can use an external gas cylinder
