Join hosts Bryan Orr, Matt Bruner, and Adam Mufich as they moderate a panel of HVAC experts including Jim Bergmann, Jim Davis, Tony Gonzalez, Bill Spohn Sr., Tyler Nelson, and Louise Kellar. The panel discusses Practical Uses of Combustion Analysis.
Topics covered in this livestream include:
The importance of combustion analysis for HVAC technicians
When and how often combustion analysis should be performed
Protecting yourself and your customers with CO monitoring
Common challenges with combustion analyzers
Practical applications for improving combustion efficiency
Getting the most out of your combustion analyzer
Real world tips for proper system setup from industry veterans
With decades of combined field experience, the panelists will share their insights, opinions, and advice for properly using combustion analyzers in both residential and commercial applications. Whether you're new to combustion analysis or looking to improve your skills, this info-packed discussion will give you the knowledge and confidence to start testing and tuning systems for peak performance and safety.
Join us for an insightful and engaging conversation you won't want to miss! The livestream will be archived on the HVAC School RU-vid channel afterwards if you can't watch live.

I always liked your jokes Bryan. Liked how you added SOME personality to the weekly Tech Tip Emails I would get from you, when I could afford to read them, since I have not been able to in years do to work. And/or being so overwhelmed by the information in them that I knew if I opened it, I would be losing hours worth of time now becoming a specialist in whatever tech tip you were going over.

This has been a great conversation about CO. I would have like to hear more about combustion analysis in regards to Nox, temp. Lean and rich fuel. With adjusting your settings. Thanks for sharing all your great knowledge

" happiness is in the air rich line " Oh, if only the Automotive industry wouldn't disappear every Engineer, in the decades past, that said that to them. :(

Damn what a powerhouse panel, thank you Brian for putting this together. Could Tyler provide more information about the studies he was citing about longterm low-level CO exposure on HVAC Technicians?

@HVACRSurvival 8 месяцев назад

Great information!.. But I wish more time was spent on the relationship of co2 and access air readings. From my prescriptive once you adjust your gas pressure and temp rise to meet factory spec and if your CO level is under 100ppm (normally is under 18ppm) what's left to adjust? Are you suggesting someone sacrifices the CO levels to reach a certain CO2 level or excess air levels. There's only so much adjustment on today's 90% & 80% furnaces after the basics are completed.

You adjust the furnace by clocking the meter and setting it to the rated input. The furnace in engineered, it just has to be set to it specifications. So gas input and temperature rise are the main two adjustment. That said, 3.5" is a nominal pressure. After clocking the meter you will adjust the manifold pressure to between 3.2-3.8" to get the input correct then verify correct/safe combustion.

You adjust the furnace by clocking the meter & setting it to the rated input (of course to actually do this you have to disregard the facts provided by the gas wobbe regarding actual fuel content values not being known). The furnace is engineered (and of course we see numerous engineering short comings in the real world of all the things that were never considered in the laboratory). So gas input & temperature rise are the main two adjustments (if you don’t consider barometric dampers to control draft, spill switches to ensure safety & residence time in the heat exchanger on 80% equipment to ensure optimal heat exchange & ball valves giving adjustment of excess air on 90% equipment). There are two different approaches presented here & they both have the potential to solve some problems. One of them just makes a lot of assumptions, which is concerning. One of them involves making corrective changes & measuring, adjusting & testing to confirm the solution. The other involves making assumptions, the adjustments & then assuming the problem is solved, while other potential issues are avoided entirely because the engineers & manufacturers didn’t consider them in the laboratory. There is no question that both ways have good intentions, unfortunately intentions alone do not guarantee to make the world a safer place. Every day is a school day & open minds will evolve & solve problems with the best facts available to them.

@@MrLaffertyheating that is why we set it up for average heat content and provide excess air in the design. It is geared towards safety rather than efficiency.

Bryan, thanks for this video. What is the best personal CO detector? Is the UL-2034 standard the only requirement?

@MR-backup 8 месяцев назад

36:30 Does anyone know which Code he's stating here?

@mathman0101 8 месяцев назад

The US is seriously behind Europe and UK around combustion testing of heat appliances, in fact it’s a legal requirement for many rental properties and is a key part of annual service plans in those countries. Just doing this would save lives in the US. Around 400-2000 people in the USA die from CO poisoning the higher number reflects unintentional or deaths linked to longer term CO exposures. While testing is the most important what is even more important is for people to think about these test results and think about the exhaust path and identify other sources of CO from gas ranges, water heaters and CO from garages coming into the residential space.
