Alcahol cooker
I am inclined to think (without knowing anything about the subject) that the pressurisation is only to allow the tank to be fitted below the burner which is best for gimble mount as it brings the CofG lower.
I am pretty sure you will need to preheat the burner. This means pressurise the tank, open the valve until a little alcohol fills the bowl. (about a tablespoon full) That is assuming it has a little bowl under the burner.
Light this alcohol and wait until it is almost burnt out. (it could take a full minute) Then open the valve to allow more alcohol in. The new alcohol will vaporise in the now hot tubes to provide a flow of hot gas into a ventury which sucks in air which is fed to the burner outlet holes. Giving the lovely hot blue flame.
If you get a flare up of flames then it is burning the alcahol as a liquid. You must get the preheat tube hotter. Turn off the valve as more alcohol will cool the pipes and start again filling the bowl.
Be careful and make sure every one who sues it is trained. olewill
