The tables for wiring on http://www.espruino.com/ESP8266 do mention that you should connect CH_PD to 3.3v... Or were you looking somewhere else for wiring info?
I think CH_PD stands for 'Chip Power Down' - it would have been nice if the board was set up so it powered on at startup, but unfortunately it looks like you do have to connect it to 3.3v to get it to start...
