Yes Nick.

Normal burner pressure is 3.5 Inches Water Colunm or IWC (also called
Inches Water Gauge or IWG). That is about 2 ounces per square inch.
Th check the proper firing of the water heater, you want to measure the
burner pressure, also called manifold pressure. There is a pressure
regulator built into the water heater thermostat assembly. Your
incoming pressure should be less than 1/2 PSI which is 14 Inches Water
Column. Normally the incomming pressure should be between 7 and 14
Inches Water Column, but check the label on the water heater.

SQLit, 11 ounces sounds like too high incoming pressure. 11 Inches
would be more correct.
