  • Page 3: Be Safe

    Safety Be Safe Tens of thousands of kilns are used safely in homes, schools, and professional studios throughout the world. With a good understanding of your kiln and a little common sense, you can avoid any accidents. Please observe the following safety recommendations: ●...
  • Page 4 ● Always unplug the kiln before performing any repairs or general maintenance. If your kiln is wired direct, turn off the breaker. ● Use only Skutt replacement parts. Improperly sourced parts may pose a hazard to you and your kiln and void your warranty.

  • Page 7: Quick Start

    Quick Start Quick Start Quick Start is a memory aid, not a substitute to reading and understanding the manual. Activate the power source by plugging in the kiln or controller. After plugging in the kiln, the display will read WAIT for approximately 10 seconds while power is restored to the kiln. It will then switch to Idle Mode.

  • Page 8: Set Up

    Set Up Set Up Your Skutt kiln has traveled a long way by rail or truck. Look for any signs of damage caused by transit. If damage is found, call your freight agent and ask for an inspection. Do not discard the packing materials, they may be needed later.

  • Page 9: Locating The Kiln

    ● When installing a kiln in a room with a fire control sprinkler system, do not place kilns within a 10 ft. (3m) radius below sprinkler heads. If this is not possible, contact Skutt for alternative solutions before installing. Be sure temperature rating of sprinkler heat detector will be adequate for normal operation of kiln at peak temperature.

  • Page 10: Preparation

    Set Up Preparation Certain kiln models may have slightly different set-up instructions. Special set-up instructions for PK Kilns and the KM-1 Wall Mount Controller are located in the Appendices section. ● Save packing material until test fire is complete. The kiln comes almost completely assembled. If you need to disassemble the kiln to make it lighter or smaller to move through doors, see Appendix 1.

  • Page 11: Test Firing

    Set Up Test Firing The test fire is very important and should not be skipped. It accomplishes several objectives ● Ensures the kiln is operating correctly and nothing was damaged in shipping. ● Burns off element oils and develops an oxide coating which will help prolong the life of the elements.

  • Page 16: Choosing A Programming Mode

    Uneven Heat Distribution Kilns will tend to fire cooler on the top and the bottom. Skutt compensates for this effect by putting hotter elements in these spots. If you notice a certain area consistently firing cooler, load those areas a little less dense.

  • Page 17: Programming Cone Fire Mode

    Programming Ramp/Hold is generally considered an advanced form of programming. It requires in-depth knowl- edge of heatwork and a good feel for how your kiln performs under a range of conditions. Graph to the left is an example of a simple glass fusing Ramp/Hold program. Programming Cone Fire Mode Step 1 From Idle Mode.

  • Page 18: Description Of Steps

    Heatwork needed for the clay or glaze to mature. The Heatwork is measured through the use of Pyrometric Cones (see pg 43.) The values of these cones used by the KilnMaster controller ranges from Cone 022 through Cone 10. It will not let you enter a cone value outside of this range.

    Programming Description of Steps RAMP/HOLD Ramp/Hold Mode is a mode of programming that allows you to write your own firing program. When you are entering your program, you will notice data already stored. Simply write over this information. If you mis-enter data, you may either press zeros to clear the data and re-enter it, or if you have already entered a rate or temperature, you can press REVIEW to go back one step.

    Menu Features Menu Features The KilnMaster 700 Board has the ability to do self-diagnostics. It can now show the voltage and amperage directly from the display, eliminating the need for expensive test equipment or having to hire a technician. Look through the entire MENU selection to become familiar with the options available to you.

  • Page 25: Set (Settings)

    Menu Features SET (Settings) SET, is where all of the commonly used options are located. The following options are available under the SET heading menu: PRHT (Preheat) ● This option allows you to toggle the Preheat feature ON or OFF. The Preheat feature allows you to Input an amount of time to hold at 180˚F (82˚C) prior to running a CONE FIRE Program.

  • Page 26: Volt (Voltage)

    AMPS (Amperes) ● This is probably the most useful diagnostic tool available to you. All KilnMaster kilns produced after 3/20/2006 are equipped with a current sensor in the control box. This allows us to test the current of each output to the kiln.

  • Page 27: Cnfg (Configuration)

    A CONE FIRE offset adjustment is normally used to adjust a specific CONE FIRE program and Thermocouple offsets are normally used on kilns with multiple thermocouples. If you think your CONE FIRE program may need an adjustment, contact a Skutt technician to assist you with this.

  • Page 28: Zone (Zone Control Options)

    Your kiln should be properly programmed for the correct number of thermocouples before it leaves the factory. All KilnMaster kilns will be set at 1 thermocouple except the high-fire KM1627PK which comes standard with Zone Control. You cannot set a kiln to fire in more than one zone unless it is configured in the factory as a Zone Control kiln.

    Troubleshooting Questions and Answers How can I correct a value that’s been incorrectly typed before pressing Enter? ● Clear the display by pressing all zeros, then input the correct number and press ENTER. When a cone value has been incorrectly entered, the process is slightly different. After pressing 0000, press ENTER. The display will again ask for a preheat value and then a cone value.
  • Page 37 Troubleshooting The kiln is plugged in, but there is nothing on the display. ● First check your circuit breaker to ensure it has not tripped. If the circuit breaker is okay, check the fuse. The fuse is located on the bottom of the KM 1 Controller and on the lower left side of the kiln mounted controller.

    Preventative Maintenance Preventive Maintenance All Kilns Vacuum floor and element grooves regularly. Carefully vacuum around thermocouple and elements. Leave KM kilns plugged in when you are vacuuming to ground any static charges that may occur at the nozzle tip of the vacuum. Try to keep the vacuum away from the touch pad area. ●...

  • Page 39: Repairs

    Repairs Repairs Brick Replacement The premium brick used in Skutt walls will withstand thousands of firings without crumbling. Broken element grooves are usually the result of carelessness in handling the kiln sections or in loading shelves. It’s almost impossible to cement a broken groove lip back into place without contaminating the heating element.

  • Page 40: Lid Maintenance

    Cone 06 or hotter firing. Lid Maintenance Skutt lids are coated with a refractory cement which helps protect the kiln chamber from falling brick particles.This refractory coating will form hairline expansion cracks after the first few firings. This is normal and should not get worse over time.

In a KilnMaster Kiln the computer calculates the heatwork and shuts the kiln off at the proper heat and time combination.

  • Page 44: Appendix 4 - Loading Tips

    Appendices Appendix 4 — Loading Tips ● Balance the Load. ● When planning how to load your kiln, keep in mind that the center of the kiln is generally the hottest. Therefore, you will want to distribute the load with the larger, thicker pieces towards the middle and the smaller, thinner pieces towards the top and bottom.
