This hotel is very fortunate to have you doing their much needed maintenance. This level of workmanship using specific test instruments and meters is from a time in the past when people took pride in their work! That combustion gas analysis test has probably not been performed since it was installed new. Attention to details makes the difference in life! Top notch quality JMT!

[chrisgotgame]

Nice job JMT these tests are very important and for safety for everyone! 👍

[jrh]

Solid Gold Tutorial very helpful as always and useful 💯👍👍👍

[keovongvilaykeo]

Always great maintenance is key thanks 🙏 you

[zekenzy]

Another Great Video as always. Thank you for sharing. Have a nice weekend.

The analyser calculates combustion efficiency by comparing the temperature of the boiler room (inlet temp) with the temperature of the flue gases. When you turn the analyser on it takes the inlet temperature reading from the probe and stores it. After that it switches to reading the flue temperature. You could also connect another temperature sensor so the analyser can read both temperatures in real time for better accuracy.

[robertpenczar]

Your videos are always interesting and informative

[nicolerennie]

went from Saturday morning cartoons to Saturday mornings with JMT. great video!! ⭐️

[JesseDoesHVAC]

Also open/natural draught flued gas appliances should really be negative pressure tested on cold draw to rule out combustion gases being pulled back into the room with exhaust air etc

[coreyr]

You should print out or leave documentation of your test results. Very interesting video

[avi-tar]

Does that boiler have NOx catalysts? If so, that might be the reason for lack of free O2 in the flue gas.

[maniek]

Omg galvanized sheet flue pipes? In Europe (greetings from Poland :D) acid-resistant steel is used and such cases never occur. Well, every country has different laws ;)

[kevinryan]

@david-ml1be looks like a badged up version of a 'kane 358' analyser we use in the uk, they have a solid reputation.

[hh-oqgc]

🫡 been looking for one of those meters for testing hobart ovens nice info

[David-mlbe]

Can you link the video of you testing gas pressure ?

Also what do you think of UEI? I like their interface

[danielblackall]

Perhaps you need to set up your 02 calibration because as you say you should be reading something for 02 and excess air. Air will have approx 20.9% 02 for a reference.

[gantmj]

Fresh air outside? More like 20 miles away.
Man, that Water Worker tank is crap from Home Depot. Need a real tank in that place.

[alimohame]

If you dont have O, you will have a lot CO maybe sensor is not reading
