A: No, using a Cone 6 instead of Cone 06 can ruin your ware. Always follow the recommended firing temperatures.

Q: How often should I adjust the kiln sitter?
A: Check and adjust the kiln sitter periodically, about every 20-30 firings or if the tube assembly in the kiln has been bumped by a shelf while loading.

Q: What should I do if I have doubts about operating the kiln?
A: If in doubt, turn off the kiln and contact your dealer or the factory for assistance at 863-648-0585 during M-F 8-4 Eastern Time.

Read and understand all operating instructions before operating your kiln.

SAFETY PRECAUTIONS

Kilns are as safe as any other electrical appliance when used under normal and proper operating conditions. All safety precautions throughout this manual should be observed.

  1. Do Not install kiln closer than 12 inches from any surface. Minimum of 18” for drywall and combustible materials (Also, read first paragraph of page 2 “Choosing a Location”).
  2. Do Not place the kiln on any flammable surface (i.e. Carpet, Wood, Linoleum, etc.)
  3. Kilns have to be on the Kiln Stand or base brick provided.
  4. Make sure all electrical specifications are followed. Use correct voltage, wire size (or heavier) and breaker. Make sure all connections are tight. Avoid using aluminum wire.
  5. Always use the proper receptacle.
  6. Install in covered, well-ventilated area. Fumes from the ware should be vented to the outside. Never use your kiln outside! Avoid moisture.
  7. Always keep children and unsupervised personnel away. Surface will get hot and a burn could result.
  8. Do not operate kiln over maximum temperature rating. (Ceramic to 2300°F, Glass to 1700°F)
  9. Fire clay, glaze, overglaze and glass only to the manufacturer’s recommended firing temperature. Improper fire temperatures could result in damage to your kiln.
  10. Replace any worn or defective parts with ONLY genuine JEN-KEN Kiln replacement parts.
  11. Never place anything above or under the kiln for storage, nor should anything be propped up against the kiln.
  12. Do not store or use flammable products near your kiln such as gasoline, paint, aerosol cans, paper, curtains, plastic, etc.
  13. A qualified electrician or service person should be used for all electrical service or repairs.
  14. If the kiln power cord becomes damaged or corroded, replace the cord immediately.
  15. Unplug the kiln before servicing or vacuuming.
  16. Do not touch or attempt to replace the elements while the kiln is plugged in.
  17. Kiln must be properly grounded.
  18. Never allow the power cord to touch the kiln. Never use an extension cord.
  19. Do not drop or slam the lid shut.
  20. Let the kiln cool to room temperature before opening the lid.
  21. Make sure all switches are turned to “OFF” before opening the lid.
  22. If your kiln is equipped with a kiln sitter, be sure to have the correct cone in the sitter.(EXAMPLE: Do not use a Cone 6 in place of a Cone 06) This would ruin your ware.
  23. Be sure the kiln sitter is adjusted properly, as shown in the Dawson Kiln Sitter Manual. Check the adjustment periodically (about every 20-30 firings or if the tube assembly in the kiln has been bumped by a shelf while loading.
  24. NEVER LEAVE THE KILN FIRING UNATTENDED.
  25. Use common sense while installing and using.

NOTE: If you are in doubt about anything turn the kiln off , call your dealer or the factory at 863-648-0585 M-F 8-4 Eastern Time

CHOOSING A LOCATION

The proper location is as important as choosing the right kiln. Below are some safety guidelines:

  • The best and safest place for your kiln is on a cement floor. (If not, some type of adequate fireproof material should be used beneath the kiln to prevent a possible fire hazard or prevent discoloration of the floor.)
  • Concrete blocks may be used to raise the kiln or a metal stand that is available from JEN-KEN Kilns.
  • Proper electrical service must be available. Refer to the section on Electrical Specifications.
  • Area should be free from flammable or combustible materials such as gasoline, paper, paints, plastics, etc.
  • Area should be covered, dry and with good ventilation to the outside. Kilns do not produce foul odors and fumes, but some products (like glazes, china paints and glass) go through a chemical change in the kiln. They could release fumes in the air, that with ample cross-ventilation to the outside, can be kept to a minimum. If ventilation is a problem, then call to see if an Orton Vent System is applicable.
  • A minimum of 12 inches should be allowed between the kiln sides and the nearest non-combustible wall or object 18 inches is recommended for ceramic and pottery kilns.
  • Never place the kiln in a small enclosed area (such as a closet, cabinet or very small room). The room temperature will increase past a reasonable level quickly. Air circulation and ventilation are needed to remove heat and vapors that may be released in the firing. In a larger room, the exterior of the kiln will stay cooler than in a very small room.
  • Since the exterior of the kiln gets very hot, place the kiln out of the way of children, traffic and work areas.
  • Never install a kiln outside and avoid undue moisture.
  • Never let the power cord come in contact with the kiln. The kiln may need to be rotated a little for the cord not to touch the kiln.

The kiln receptacle should be located to the back right of the kiln, about 1 to 2 feet from the ground. Review the diagram below

Installation Diagrams

Jen-Ken-AF3C-Kiln-Choice-of-Controller-1

Kilns must have an Air Space Under the Kiln. Kilns Cannot sit directly on a floor or any surface. Use a kiln stand or concrete blocks with the holes up and down at a minimum. Small Table Top Kilns can be used with a kiln stand or the kiln bricks supplied as long at the material under the kiln is not combustible.

ELECTRICAL SPECIFICATIONS

To operate the kiln safely and efficiently, your kiln needs the proper electrical outlet with the correct electrical capacity and voltage. The chart below will assist you the selection of the proper wire and breaker size for your JEN-KEN Kiln. A licensed electrician or the local power company should determine if you have the proper voltage. A kiln that is manufactured for 240 volts of service will not run properly on 208 volts. This difference of 32 volts is about a 25% reduction in power, which hinders a kiln from reaching high temperatures. Likewise, if you have 240 volts and you install a kiln manufactured for 208 volts, it will heat so rapidly it will hurt the ware in the kiln. Improper elements can be dangerous. Be sure to have the proper elements in your kiln to match the electrical service.

If you have 208 volts of service, you NEED 208 volt coils for Ceramic and Pottery Kilns. If you have 240 volts of service, you NEED 240 volt coils for Ceramic and Pottery Kilns. Most 240 volt Glass Kilns will work on 208 volts fine as they only go to about 1500F to fuse the glass. Call to ask about your situation.

Any changes to your kiln or improper electrical installation will void the warranty.
ELEMENTS: Elements are the coils of wire that produce heat inside the kiln. They are made from a high quality, high-temperature wire. During the firing, they become very soft and when cool become brittle. Life expectancy of the elements will depend on the number of firings, the firing temperatures, and the products fired. At lower temperatures, the elements will last longer than firing at higher temperatures. Care should be taken to make sure that no foreign matter (such as glazes, clay or kiln wash) come in contact with the elements. This will greatly reduce their life expectancy. Regular vacuuming of the kiln lid, bottom and the element grooves is recommended.

  • The 2829, Oval, JK Squared Series can be ordered as a 45 amp kiln or a high-fire 55 amp kiln, requiring direct wire installation. The higher amperage means the kiln can fire to higher cone numbers more times with the added power.
    NOTE: Call before installing new electrical lines for a kiln if you have questions. Kiln amperage and the distance from the breaker to the kiln is important. Call first if there are any questions, we want it to be wired up correctly the first time.
    For kilns ordered with the 208 volt elements, the amperage, wire size, breaker and receptacle may change to keep the watts the same as the voltage lowers.

IF YOUR KILN IS OVER 30 FEET FROM THE BREAKER YOU MAY HAVE TO GO TO THE

NEXT HEAVY GAUGE OF WIRE, PLEASE CALL. KILNS PREFER HEAVIER WIRE. THE FARTHER THE ELECTRICAL RUN THE HEAVIER THE WIRE HAS TO BE!!!!

Note:

  • 120 volt kilns work the best if they are within about 40 feet of the breaker. For 120v 13 amp kiln models on 14 gauge wire 40 feet and up to 65 feet for 12 gauge wire
  • Call before installing new electrical lines for a kiln if you have questions. Kiln amperage and the distance from the breaker to the kiln is important. Call first if there are any questions, we want it to be wired up correctly the first time.

KILN BRICK:
All JEN-KEN KILNS are made of hand selected 2300°F refractory brick. This brick is an insulating fire brick that has holes inside and throughout the brick to give it an insulating value. If it was solid brick it would not hold the heat inside the kiln, but transfer the heat through the solid material to the outside. The brick is strong as a whole as has a very long life. The brick can chip easily and care should be taken to avoid bumps while loading and unloading shelves. Frequently vacuum the brick lid, the groves that the elements are in and the bottom of the kiln. This will remove the dust, sand and loose kiln wash from the kiln.

KILN JACKET:
Your JEN-KEN KILN is encased in a stainless steel jacket and is also equipped with handles for easy moving. Due to the high temperatures, discoloration may appear on the stainless. A good metal polish can remove this discoloration, but most do not worry about the looks of the kiln after years of use.

ACCESSORIES

SHELVES: Shelves help you make the most of the inside of your kiln. Shelves are sized a few inches smaller than the inside diameter of the kiln so that they can be placed in and out of the kiln easier. They are made of refractory material so that they should be handled carefully. Shelves come in full and half sizes. Half shelves enable you to fire tall pieces on one side of the kiln and smaller ones on the other side. Should a crack appear in a shelf, break the shelf along the crack and use it as two separate pieces. A good coat of kiln wash should ALWAYS be maintained on top of the shelves. Ceramics uses ceramic kiln wash with silica in it and glass requires glass kiln wash with no silica, because the silica (powdered glass) will to stick to your glass. Store shelves upright on edge leaning on a sturdy structure. Shelves stacked flat can put to much pressure on the bottom shelf and cause it to stress and crack. It usually breaks in the kiln during the next heating. Kiln shelves are not perfect and are made from a high temperature clay. The may be sanded to make smoother on to take out gouges in the surface. Using a sanding block and emory cloth about 150 to 200 grit can make easier work of sanding a shelf. Sand outside with a dust make to be safe.

POSTS: Posts are also made from refractory material and should be handled carefully. Post sizes range in heights from ½” to 14”. They are used to support the shelves in your kiln at different levels depending upon the height of the ware you are firing. Usually, three posts allows you to level the shelf easier (though some prefer four). Glass kilns with lid elements usually only use one shelf at a time. The lid element does most of the work heating the one shelf and would not provide the direct radiant heat to a lower shelf. The top shelf would fire fine with the bottom shelf lagging behind by a large temperature differentiation. Posts do not need to be to outer edge of the shelf. Move the posts in several inches so that the posts help support more of the middle of the shelf. This will help keep the middle of the shelf supported from underneath without a post there. For large shelves this is required so that the shelf is not supported at the edges, but more towards the center.

CERAMIC KILN WASH: Kiln wash is a protective coating used to keep glazes and porcelain from sticking to the kiln shelf and the kiln floor. Mix the desired amount of dry, high fire kiln wash with water to the consistency of a thick cream and stir thoroughly. Apply several thin coats of kiln wash with a haike brush to the kiln floor and the tops of the shelves, alternating directions. Let dry. When areas wear thin they may be re-coated. If glazes r glass have dripped onto the shelves or the kiln floor, chip the glazes off, sand and smooth the area then reapply the kiln wash. To test kiln wash, slide your hand over the surface of the kiln washed shelf. If you hand is white and powdery, the kiln wash is satisfactory. Perform this test periodically. When the palm of your hand is clean, then re-apply kiln wash to the shelf to prevent the ware from sticking.
Apply a thin coat of kiln wash to the cone supports on the kiln sitter and to the bottom of the sensing rod (where they come in contact with the cone). However, do NOT apply kiln wash to the cone or to the side of the porcelain tube.

GLASS KILN WASH: Glass kiln wash is a coat that keeps glass from adhering to the kiln shelf and the kiln floor in the event of a glass run.

If applicable, scrape the old kiln wash off with a putty knife. It is best to wear a dust mask while cleaning and working with the kiln wash. Stir the kiln wash powder first with a spoon to mix the clays. The add the kiln wash to water. The most common mixture is 4 cups of water to one cup of kiln wash powder. Stir to get most of the lumps out. Apply a protective coating of kiln wash to the floor of the kiln. Hot glass can create holes in the fire brick of the kiln.

Apply kiln wash using a soft bristled brush to the kiln shelf. Feel free to stir the kiln wash in a mixing container with the brush (as this will keep the clays from settling). Load the brush heavily with kiln wash when dipping it in. Flow the first coat on in one long brush stroke. Repeat this with parallel brush strokes. Allow the shelf to absorb most of the moisture then apply another coat in a cross direction to the first. Repeat this for 8-10 coats. A thick layer of kiln wash will be easier to remove later and will last longer too. Too much kiln wash on a shelf is not a problem (unless it is uneven) but not enough will cause glass to stick to the shelf and eventually break. Store the unused kiln wash (liquid or powder) in a sealed container.

Let the shelf stand for several days to dry or place it in the kiln and heat it up to 500°F with the lid propped open a few inches. If the shelf surface is not smooth when dried, use the palm of your hand and rub the kiln washed shelf gently in a circular motion till smooth.

PYROMETER: A pyrometer is a meter used to measure temperature inside the kiln. A thermocouple (sensing device) is attached to the meter and the end is inserted into the kiln (through either peep hole or thermocoupler hole) obtain the temperature reading. It is useful, as a guide, to show how fast the temperature is rising and when you are nearing your desired temperature.

WHEN USED FOR CERAMICS:
A pyrometer used for ceramics measures only temperatures and should not be used as a substitute for a pyrometric cone in the kiln sitter. A pyrometer can help prevent a potential over-fire. If the pyrometer reads a higher temperature than the cone firing temperatures the time is longer than usual. Then you can turn the switch(es) to “OFF”. If you are in doubt about a firing, turn the kiln off, let it cool to room temperature, then inspect the cone and the firing. It is far cheaper to put a new cone in and refire than to over- fire the load.

WHEN USED FOR GLASS:
A pyrometer used for glass work is a useful tool that can gauge the rise in temperature over a period of time. Example: take the temperature reading, wait 10 minutes and take the reading again. Subtract the first reading from the second to find the difference. The divide this number by 10 minutes to give the rate of rise per minute.

  • First temperature reading 500°F, Second temperature reading 725°F for a difference of 225°F. Divide 225°F by 10 minutes equals 22.5°F per minute rise in temperature.

There is a ½” thermocoupler hole (in the steel jacket) located on the back right side of the kiln. If the hole is to be used, you will need to drill through the brick using a ½” drill bit for large thermocouplers or a ¼” for small ones. The hole is easy to drill by just spinning the bit with your fingers. Slowly push the bit in and out of the hole clearing the dust each time. Be sure to vacuum up the brick dust. If there is not a hole in the steel jacket, then a peephole plug may be ordered that has a hole pre-drilled through it. Then the thermocoupler can slide in through the peephole plug in the kiln.
Insert the thermocoupler at least 3” into the kiln and do NOT allow the tip to touch anything inside the kiln. Make sure the ceramic block or the alloy rods never touch the outside metal jacket of the kiln.

NEVER FIRE A KILN UNATTENDED NO MATTER WHAT BRAND KILN, MAKE OR  MODEL
LET THE KILN FIRE AND SHUT-OFF. IF THE KILN CANNOT BE MONITORED WHILE ON, THEN IT IS FAR BETTER TO TURN THE KILN OFF AND REFIRE AT A LATER TIME. THE ONCE THE KILN HAS SHUT DOWN AND IS COOLING AND POWER HAS BEEN SWITCHED OFF, THEN AND ONLY THEN, CAN THE KILN BE CONSIDERED READY TO BE UNMONITORED.
DO NOT LET ANYONE NEAR A HOT OR COOLING KILN.

KEEP ALL CHILDREN AWAY!
