Furnace Commissioning w/ MeasureQuick 2.0
Jim Bergmann returns to the podcast to talk about furnace commissioning procedures and the development of measureQuick 2.0.
MeasureQuick 2.0 has been a collaborative effort between Jim Bergmann and Joe Medosch, and it comes with an upgraded user interface that allows for faster operation and easier system data access and storage, and it works with more tool manufacturers’ tools.
Gas furnaces need to be commissioned to reach their maximum potential (and lifespan). MeasureQuick 2.0 provides commissioning instructions and recommends starting with a visual inspection, including the flame rectification system (rod, circuit board, and grounding). Electricity is conducted during the flame rectification process—only in the microamp scale—so a dedicated circuit is crucial to keep it working as it should.
When commissioning a high-efficiency furnace, we should make sure the condensate drain cannot become clogged. The filter should block the airstream completely and not allow for any bypass, which could make the secondary heat exchanger, condensate drain, or circuit board dirty. The combustion air zone (CAZ) is also important; we don’t want contaminants in there, as those could create acids that rot out your furnace components.
Jim has also recently worked with the folks at TEC to make MeasureQuick 2.0 compatible with the TrueFlow grid and DG8. This integration allows you to identify airflow issues much more quickly and easily than before. MeasureQuick 2.0 also stores a lot more historical data, especially as it relates to the built-in visual inspection checklist.
