ABOUT YOUR KILN
Introduction
The Delphi EZ- Pro
Kiln
15-6 is a professional quality Jen-Ken kiln.
The controller has been designed and programmed to Delphi specifications by
Orton Ceramics.
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 and the firing temperatures. 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 glass,
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.
In a digital kiln, the coils as a group turn on and off during firing. You will hear the
clicking of the relays. It will click more if a slow rate of rise in temperature is used and
less if the kiln is told to fire quickly. Your EZ-PRO kiln has separate relays for the top
and side elements to increase the life of the relays.
Glass kilns usually have coils in the lid and side walls. The lid coils do most of the work
in the kiln and get the hottest. Side coils are supplemental heat and help bring the kiln to
temperature. It takes the side and the lid coils to bring the kiln to fusing temperatures.
SAFETY FIRST: In a digital kiln, if a relay fails, the section that the relay controls might
not heat up, or could stay on continuously. If this happens, turn off the kiln at the
breaker and unplug. At this point, you will need to replace the relay. Call Jen-Ken Kiln
Company for assistance.
The EZ-Pro Kiln has multiple relays so that if one relay fails the kiln cannot heat too high
in temperature.
