6ABOUT YOUR KILNIntroductionThe Delphi EZ- Proļ Kiln 15-6 is a professional quality Jen-Ken kiln.The controller has been designed and programmed to Delphi specifications byOrton Ceramics.ElementsElements are the coils of wire that produce heatinside the kiln. They are made from a high quality,high-temperature wire. During the firing, theybecome very soft and when cool become brittle. Lifeexpectancy of the elements will depend on thenumber of firings and the firing temperatures. Atlower temperatures, the elements will last longer thanfiring at higher temperatures. Care should be takento make sure that no foreign matter (such as glass,glazes, clay or kiln wash) come in contact with the elements. This will greatly reducetheir life expectancy. Regular vacuuming of the kiln lid, bottom and the element groovesis recommended.In a digital kiln, the coils as a group turn on and off during firing. You will hear theclicking of the relays. It will click more if a slow rate of rise in temperature is used andless if the kiln is told to fire quickly. Your EZ-PRO kiln has separate relays for the topand 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 workin the kiln and get the hottest. Side coils are supplemental heat and help bring the kiln totemperature. 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 mightnot heat up, or could stay on continuously. If this happens, turn off the kiln at thebreaker and unplug. At this point, you will need to replace the relay. Call Jen-Ken KilnCompany for assistance.The EZ-Pro Kiln has multiple relays so that if one relay fails the kiln cannot heat too highin temperature.
