1. If uneven firing occurs persistently, distribute your load weight more evenly throughout the kiln or to match the firing characteristics of the kiln.
2. If elements typically fire hot at the top of the kiln put more weight in the top to absorb that heat, and vice versa.
3. The bottom shelf should be at least 1/2" to 1" above the floor of the kiln.
4. Badly distributed load weight can also affect the firing rate of the kiln and lead to Error 1.

TIP: The longer square posts can be laid down on their sides to get a perfect amount of space under the bottom shelf.
