Hi Nicky,
Glad to hear the kiln's arrived! Woohoo!!

To do my first empty firing, I just ran one of the 5 speed firings (I think that's how many there are???). I think I picked the middle one. (SPD3) I left the bung out and opened a window to let any fumes and pongs out - there might be a few. Also - I don't recommend you leave the kiln unattended while you do it, to make sure the kiln doesn't over fire, but I'm sure you already know all this.
Anyway - the bit where you'd normally pick Pr01, you pick Spd3 instead and press start. The kiln will then fire up quickly to the pre-programmed temp, then cool. Then once it's cooled you can start an annealing schedule with a kiln full of beady goods.

Good luck!
