Introduction
This manual covers the operation of the Genesis 3140 kiln controller. The Genesis is a versatile
touch screen controller that regulates the temperature in your kiln so you can fire a variety of products
like ceramics, glass, jewelry, and more. The Genesis has all the features of its earlier models, the V6CF
and RTC1000, along with Wi-Fi capabilities for software updating, built in diagnostics, and maintenance
logging among other new features.
Precautions
• The controller is used to control temperature; it is not a safety device.
• Do not operate the controller in temperatures above 160ᴼ F.
• Always supervise your kiln during a firing.
• The controller contains electronic components which are sensitive to static electricity. Before
handling the controller dissipate any static charge you may have by touching metal or a
screw on the controller panel, the electrical box, the kiln lid, or some other grounded
object.
• Always check the position of the thermocouple probe before starting a firing. The current
temperature displayed on the controller is measured at the end of the thermocouple which
must be in the firing chamber about 1” to 1-1/2”. Seal the opening around the thermocouple
with kaowool or similar material if necessary.
• Always review the current program before firing to ensure the correct profile is
programmed.
• Ensure the kiln and the areas around the kiln are clear of combustible material. See kiln
manufacturer’s recommendation on required clearances.

Programming for Custom Firings
The Genesis has 12 Custom user programs to store and reuse. The custom programs can have
anywhere from 1 to 32 segments. Each segment has a firing rate, a soak temperature and a hold time.

1. The first ramp rate of any user program must be an increasing ramp which means
the segment temperature must be greater than the starting kiln temperature.
2. To ramp up or down at the maximum rate, enter a rate of 9999.
3. To program a down ramp, enter the rate/hour then a temperature below
the previous segment’s temperature.
4. It is best to write out the firing profile that you plan to program before you begin
programming. A blank form for writing your firing programs can be found in Appendix
D: Blank Firing Program. Photo-copy as needed.
Calculating Ramp Rates for Custom Firing
If you want to go from room temperature to 750°F in 3 hours, use this method to
calculate the ramp rate. Take the temperature that you want to go to (750°F) minus the
starting temperature (70°F – approximate room temperature) to get the number of degrees
you want to increase in 3 hours (750 – 70
= 680). Divide this number by the time you want to get to 750 to give you the ramp rate (680°F
÷ 3 hrs = 227°F/hr). If you want to add another segment to go from 750°F to 1000°F in 4 hours,
the same procedure is used. Take the end temperature minus the starting temperature (1000
– 750 = 250) and divide this number by the number of hours to reach 1000°F (250°F ÷ 4 hrs =
63°F/hr).

Ceramics Programming (Bisc or Glaze)
Programming in Novice mode is the easiest method to program the controller to fire ceramics.
Programming consists of choosing a cone number, firing speed, and a preheat time. The firing speed is
chosen by the type of firing and thickness of the clay used. All 4 speeds below will calculate the firing
rate at the end of a firing and adjust the final temperature for correct heat-work.
