In reply to Derry:
Fine, I was excessively blunt.
There are multiple hazards associated with using a stove indoors:
Carbon Monoxide build up (not a huge issue unless multiple people are cooking as the actual mass of gas burned is quite low, if multiple people are cooking you can always open the door a bit to allow it to escape)
Fire hazard from people's kit nearby
Fire hazard from incorrect assembly
Fire hazard from leaking of gas due to perished seals
If it's not lashing it down, or thick with midges it's more sensible to cook outside, away from any thoroughfares, particularly if the bothy is busy, or people are drinking.
