The first step is to develop a set of readings on your tunnel kiln. Select a manometer with sufficient sensitivity-0.001 in. resolution-so you can develop an internal pressure curve of the kiln. Try to measure the pressure in the kiln every 20 ft, and measure the pressure at the same elevation (preferably close to the kiln car base).Web
