How it work : It works with the steam. We use carosine oil burner to work this fan. It include carosine lamp burner for steam. We will send instruction if needed. Burn the carosine ol burner and keep it inside the fan. Move the piston after two minuts. After 3-5 minuts move pistons which move blades after that time it will work automatically. So please keep moving piston when you put the burner inside the fan. For any help you can ask me anytime.
