I just checked the operating manual that I have and it is the same one @Bill Kielb notes in his response...go with that. I used those basic instructions with my B23H for a year with good outcomes for low fire work until I installed and Orton digital controller. I ultimately sold that kiln to someone who just wanted to do low-fire work and bought a used FX23 to do cone 6 work and just plugged the newer kiln into the Orton controller.
