In this episode of the HVAC Know It All Podcast, host Gary McCreadie dives into advanced combustion analysis with Jason Esteves from Seitron Americas Inc. The episode builds on previous discussions of basic and intermediate combustion principles, diving into the stoichiometric curve—a key concept for mastering combustion efficiency and safety.
Jason Esteves is a seasoned expert in combustion technology and training, representing Seitron Americas Inc. With over 20 years of experience in the field, Jason combines technical expertise with a passion for educating HVAC professionals, making complex combustion concepts accessible and practical for technicians in the field.
Expect to learn:
Theoretical Combustion: Stoichiometric combustion is a guiding principle but impossible to achieve in practice.
Efficiency with the Curve: Use the stoichiometric curve to balance efficiency and minimize CO emissions.
Analyzer Tools: Advanced features like "Pro Mode" simplify diagnostics for technicians.
NOx Emissions: Modern systems reduce harmful NOx emissions caused by high-temperature combustion.
Avoiding Errors: Proper venting and following manufacturer specs ensure safety and efficiency.

Gary McCreadie takes us on a commercial HVAC service call troubleshooting a Carrier rooftop unit.
The problem was not 100% apparent, it took a little leg work and a couple of visits to solve.

Hot surface ignitors or HSI for short vs. Direct Spark. These are two different methods that natural gas or propane appliances use to ignite the flame for heating purposes.

The changes are coming quick and fast in the HVAC and Refrigeration Industry. Keeping up and adapting will ensure we don't become complacent in our day to day.
We speak to HVAC business owner Zach Karre about how adapting quickly might be our best option.
Gauging up to systems is not always necessary but if you do, it's best not to lose refrigerant in the process if at all possible. Using low loss fittings, ball valves, gas retention valves or other can help with this.
In part 2 of 3 we speak to Jason Esteves from Seitron Americas. We discuss intermediate combustion analysis. Jason tell us how to get proper combustion efficiency in a 2 pipe system. We also briefly discuss how to find cracked heat exchangers using a combustion analyzer.

We speak to Keith Clark and John Fanetti from ICM controls about low ambient air conditioning and refrigeration operation. We compare fan cycling vs fan speed. We discuss the ICM 325A which can control fan speed based on temperature or pressure.
