This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, a valve leakage test and/or other tests may be performed on a valve assembly including a valve body with a first valve and a second valve, where the valves may be positioned across a fluid path in the valve body with an intermediate volume between the valves. A human machine interface (HMI) may be in communication with the valve assembly to initiate and/or monitor tests on the valve assembly. The HMI may include a start button on a user interface for initiating the tests on valve assembly. The HMI may receive results of the tests (e.g., valve leakage tests) in real time during the test and display the results of the tests on a display of the HMI in real time.

A controller monitors oxygen levels in a bio-fuel fired device and automatically controls dampers, blowers and the like to reduce generation of smoke or other pollutants, thereby promoting proper operation of a catalytic converter.
