One of the most important tasks in maximizing efficiency and safety in heating appliances is to perform an accurate combustion analysis test. Understanding how to measure oxygen, carbon dioxide, carbon monoxide, and draft pressure will improve the efficiency, performance, and reliability of the heating system. In this session by Tony Gonzalez, attendees will gain a better understanding of what combustion analyzers do and how to use them on several types of heating appliances effectively. This session is loaded with a-ha! moments and some neat discussions about tools.
