Tyler is awesome. We had him at our shop.
Thats awesome!
I did your preventative maintenance for AC 2023
Awesome re-education on the value of using a combustion analyzer
Thanks for this video
Thank you very much for all this information! it inspired me to get this tool for my new one man company. I understand the general idea of what this tool does and how it's done, however I would like to see videos of how it's used in the field. I noticed the Manuel ,and what this video says is a bit different . so I to be honest the Manuel doesn't have a lot go info as far as instructions. I would love for you Craig to show a how to , step by step, how to use this tool. examples of when to start the furnace up, when to have the probe in, when doing a heat exchanger test. a pass and fail. how long should a test take and so on. again I thank you for all of your content and all your help! God Bless!
Great video, thank you for sharing. As a fellow instructor I can appreciate sharing good information to the instructors and Technicians. I was wondering if there is a way to get a copy of the venting images shown in the beginning of the training video.
Greatly appreciate these type of videos thanks for all the good work you guys do to help technician
Great Presentation Tyler!!
Earl
Great presentation. Thanks.
Also, please make an on the job demonstration. And explain the importance of the other gases in Combustion Analysis
Great feedback. This is where coming to one of my live classes comes in where we do hands on. I do them all over the Americas.
@@tyty3022 when & where?
I FGA every unit I isolate. Be it for a strip or cleaning a condensate trap. Always go home with a clear conscience. That flue piped to the basement is paying for death.
The UK has very high standards; retrain every 5 years mandatory. Its bloody hard work here hence £90 per hour rates.
Great presentation. Thank you .
You are welcome!
Great video thanks for sharing
Can you please make a video on chamber vacuum sealer machine. Please❤️
great information
Very informative video thank you and Craig 👍👍👍👍👍
Glad you enjoyed it!
Great presentation, very digestable for a novice. As a home owner, i wonder why we use gas in residential applications at all? I gather price is the main factor but it seems to me that electric system like heat pumps are far safer and qsuming a competent installer, better for ghg emissions
There is some push back on the pvc vs. pp change over. PP has it's own problems such as it's prone to oxidation in some environments and it doesn't withstand heat as well as pvc.
I am certified in this been doing it for many many years in Los Angeles Orange County retired now people talk about cleaning up the atmosphere I did there are many other safety factors
Great presentation gentlemen! Curious on your thoughts about adding a valve on the inlet air (NCI often talks about this)? Also - I'm in canada - we have different codes as far as penetrating the flue pipes. You mentioned PVC is going away, but we're required to use the ULC S636 rated PVC - not sure if that's going as well - or anything else (polypro) rated to s636. the pipe manufacturers have a fitting for combustion analysis that is basically a 2x2x1/2 FPT fitting. Will the threads of the cone thread into this ok? I previously carried around a 1/2 plug cap that I drilled a little hole in to put the probe into because I was worried about the threads not matching. Thanks again! Appreciate your hard work!
Unrated PVC is going away. 636 is rated and listed as a venting material. Polypropylene (polypro, centrotherm, and others) are also rated, and some glue “PVC” products are as well, 1738 and 636 for example. As approved fittings and systems, they offer test ports. Great idea in my opinion, use approved fittings and avoid liability problems
Why are those carbon monoxide detectors allowed to be sold if they’re not effective at all? Can we sue them?
How does someone get a hold of Tyler? Anyone?
Nice training, but I see only CO reading on your combustion examples, I didn’t see COaf, on you combustion examples.
It was farther down on the display. You can change what you see and in what order on the analyzer. I have since moved it up as number 2 under O2.
I understand how a high setting of manifold pressure could increase the dimensions, particularly the length, of the flame, reducing distance to the heat exchanger walls until the point of causing flame impingement. But, at 40:02, Tyler reads from the slide that a LOW setting of manifold pressure can cause flame impingement. How would a decrease in flame dimension cause impingement? Have I misunderstood somewhere or is it just an error on the slide?
Error on tbe slide my friend. Transposition error. Apologies.
Is there a resource to download the power point presentation as a pdf
What training material are those chapter references at the top of the screen from?
29:11 Wouldn't keeping the hoses attached mean that the startup would negate any contamination from past analyses left over in the hoses?
Great question my friend. If you had kept the hoses attached at start up you run the risk of pulling the remnants of a previous combustion test into the analyzer and thus skewing the auto zero process. Auto zero is always done with no probes or hoses attached and away from potential contaminants.
@@tyty3022 I appreciate the quick replies. Let me know where I can learn more. I'm also looking to upgrade from my Testo analyzer
I’ve always heard to not have your analyzer in the flue during light off due to it damaging your sensors from the high CO on ignition, is this not true?
Little of both. Newer machines have a “cutoff” threshold you can program to protect them from spikes, many older machines did not just make sure yours does, and it’s programmed to work!
It was true. However, with the Sauermann SICA combustion analyzers we give you a robust 8000 PPM limit with programmable pump cut off so you won’t over range your CO sensor. That is why I want those who use ours to test at all firing rates. This is another reason why NCI uses us as well as a great deal of others switching to us. We also have sensor life indicators and end of life indicators plus other class leading features.
Install those boards often. Just half to rotate them sideways and will not have to extend any wires!
38:54 - I have a challenge for you: how do I clock the meter in a restaurant with four RTUs, two gas griddles (one - 2 foot and one 3 foot) and one two eye burner?
Hi!😊
How about proves? No mani.
this was more a selling piece for that too.. my fieldpiece cat85 is way better than that tool.
It's too general, not enough specifics. Also he just talks and never actually says anything useful.
If you didn't find anything useful then you are unteachable. Hopefully you're happy as a barista.
@@timdestasio3367 nobody cares what you have to say.
@@CybekCusal 👏👏👏 I'll have a large black, 1 sugar please and thank yoy.
@@timdestasiohvac you guys have no life but to be Internet small d trolls
What would you have added?
