In this episode of HVAC Know It All, host Gary McCreadie talks with Tyler Nelson, Master HVACR, HVAC Sales Manager & Trainer - Americas at Seitron Americas Inc., about testing combustion at light-off, steady state, and shutdown. They examine what each phase can reveal about burner operation, heat exchanger integrity, and fuel delivery. Technicians will learn why steady-state readings alone can miss diagnostic clues and how analyzer protection affects testing practices. Tyler wrote Combustion Analysis: The Essentials and recently joined a collaborative team of trainers at Seitron Americas Inc. His teaching connects analyzer readings to a diagnostic thought process: what a technician observes, what it might mean, and what to check next. That approach also informs his use of multiple tests when evaluating a suspected heat exchanger breach.   Key Takeaways How testing at light-off, steady state, and shutdown reveals different operating characteristics that steady-state testing alone can miss. Why Nelson uses CO air-free readings to evaluate combustion and distinguishes light-off thresholds from steady-state thresholds. How monitoring oxygen after the blower starts can help identify a suspected heat exchanger breach as part of a broader verification process. How shutdown readings can reveal clues to a leaking gas valve, residual oil, or a secondary heat exchanger drainage problem. Why light-off testing requires close attention to analyzer sensor protection, and why temporarily closed supply registers must be reopened after static-pressure testing.   Key Timestamps 00:00 - Factory Direct Filters Ad 00:42 - Guest and Episode Introduction 02:24 – Defining light-off, steady state, and shutdown 09:20 – CO air-free readings and combustion evaluation thresholds 15:58 – Analyzer protection and focused attention during light-off testing 17:48 – Static-pressure testing within a multi-step heat exchanger evaluation   This Episode is Kindly Sponsored by: Cintas: https://www.cintas.com/hvacknowitall Cool Air Products: https://www.coolairproducts.net/  Factory Direct Filters: https://www.factorydirectfilters.com/  SupplyHouse: https://www.supplyhouse.com/tm  Use promo code HKIA5 to get 5% off your first order at Supplyhouse!   Follow the Guest and His Company on: Tyler Nelson, Master HVACR - LinkedIn: https://www.linkedin.com/in/tyler-nelson-master-hvacr-9a8a981b/ Seitron Americas Inc. - LinkedIn: https://www.linkedin.com/company/seitron-americas-/inc Seitron Americas Inc. - Company Website: https://www.seitronamericas.com/    Follow the Host on: LinkedIn Profile: https://www.linkedin.com/in/gary-mccreadie-38217a77/ LinkedIn - HVAC Know It All: https://www.linkedin.com/company/hvac-know-it-all-inc  Website: https://www.hvacknowitall.com Facebook: https://www.facebook.com/people/HVAC-Know-It-All-2/61569643061429/  Instagram: https://www.instagram.com/hvacknowitall1/   Follow the Podcast on:  YouTube: https://www.youtube.com/@HVACKnowItAll  Spotify: https://open.spotify.com/show/6LCBJGw0EHG03rdWHxUMce Apple Podcasts: https://podcasts.apple.com/us/podcast/hvac-know-it-all-podcast/id1359253455
