How To: Test/Adjust Gas Pressure Measure the inlet static pressure (valve off) & load pressure (valve on / energized). Step 1 Measure the outlet manifold pressure (valve on / energized), as shown below. Step 2 The static & load values should be within the levels listed on the data plate, example on Page 17. Manifold reading should be between 1.8"- 2.0" w.c for natural Gas or 6.8"- 7.0" w.c for propane. NOTE: Please refer to Installation Manual for proper gas line sizing. 16

.
Manifold reading should be
between 1.8”
-
2.0”
w.c for natural
Gas or 6.8”
-
7.0”
w.c for propane.
