Adjust Gas Pressure On A Furnace

In order to properly adjust and / or maintain a residential gas furnace, a manometer is needed. Digital manometers are prefers as opposed to U-Tube variations, due to the readout display. A manometer can read the incoming pressure of gas in a gas fired unit. Some combustion analyzers, such as the Wohler A 450, also offer the feature of measuring the gas pressure.
