Before changing heating elements, you must know if your kiln uses more than one type of element.
The top and bottom are the most difficult areas to heat in a typical top-loading electric kiln. Since these areas require extra heat, the top and bottom elements of most Paragon SnF and TnF kilns generate more heat than the center elements.
If a top/bottom element is reversed with a center element, the kiln will fire unevenly. So when you receive a new set of elements, check the element labels. Install elements marked TOP/BOTTOM and CENTER in the correct locations.
Your kiln's wiring diagram and the element price list will show if your kiln uses top/bottom and center elements. (Some kilns use only one type of element throughout the firing chamber.)
When ordering elements, give the correct kiln model number. This is shown on the kiln's electrical data plate-the small black plate riveted to the side of the switch box.
