The L&L Plug-N-Fire is the first cone 10 electric kiln that can operate on a standard 15-amp circuit. Measuring 8 inches square by 9 inches high (0.33 cubic feet), this compact test kiln offers the durability and features you expect from L&L in a versatile, small package.

  • Designed for almost all 15 amp 120-volt circuits (for USA models).
  • Great test kiln and hobby kiln.
  • Please follow these instructions to assemble and install your kiln.
  • Be mindful of where you use the kilns because of heat.
  • Also, be sure to use it in a well-ventilated area.

  • No Vent Needed: Compact design eliminates dedicated vent system.
  • Ventilation Tips: Use in a well-ventilated area for performance, air quality, and safety.


  • Floor Surface: Use non-combustible surfaces (cement, ceramic, stone, slate, cinder blocks, brick).
  • Avoid: Wood, vinyl, carpet; protect linoleum with a non-combustible covering.
  • Work Table: May be placed on a non-combustible raised table.
  • Clearance: maintain 18" clearance from non-combustible walls, 12" minimum; 3 feet from combustible surfaces.

Your Plug-N-Fire will arrive in two separate boxes. Box 1 (blue) contains the main ring and the Genesis mini controller, while Box 2 (red) contains the stand, bottom, lid, and furniture kit. Unpack both boxes and keep everything organized.

If you need to relocate the Plug-N-Fire kiln, you can easily disassemble and reassemble it at the new location. However, it's crucial to be aware that kilns expand and contract during the firing process, which can cause the steel case to loosen over time. Therefore, if the kiln has been fired, ensure you tighten the steel case before moving it. This precaution helps maintain the kiln's structural integrity and ensures safe transport.


Due to the additional backup insulation in your Plug-N-Fire kiln, it may tend to fire hotter than your control is programmed to. To address this, we recommend reviewing our detailed calibration page to thoroughly understand the calibration process.

However, a simpler workaround that you might consider before diving into calibration is to program the kiln to fire at a lower cone than your target. For instance, if you aim for a cone 6 firing but notice the kiln is reaching cone 7, try setting the program to fire at cone 5 instead. For lower firings, such as cone 06, try setting the kiln to fire two cones lower at cone 08.

Additionally, incorporating a custom slow cool segment at the end of your firing, which can be beneficial for certain glazes, may increase the heat work. You'll need to compensate for this accordingly. Always use witness cones to monitor the firing process and make necessary adjustments.
