The ENO can use propane or butane. The oven gas burner has an air ring adjustment for the different gas. If it has been set up for butane, the oven will work better with a smaller air opening. On my oven, the instruction manual calls for the gas ring to be set so that the air opening is 6mm for butane and 4mm for propane.
Your planned voyage sounds great.
