Natural vs. Propane Gas. If you plan to use natural gas with your kiln, a large burner is necessary when used on natural gas pressure, you will need 6-8 inches of the water column. If you order your kiln for natural gas use, it will be equipped this way. The natural gas pipeline that connects to the kiln needs to be one that has a 3/4" inside …

Using the Trash Can Kiln. To heat the kiln, a propane burner torch is positioned at the burner port at the bottom of the kiln. It is best to position the torch an inch or so away from the entrance. This allows air to be drawn into the kiln. If you put the burner too close, less air gets in. You may find that the kiln struggles to heat up.
