Summary

Bill and Bryan discuss gas and combustion tools. These tools include manometers, combustible gas detectors, personal CO detectors, draft gauges, and combustion analyzers.

Manometers measure gas pressure, and they require calibration but are usually quite accurate. Before using a manometer as a diagnostic tool effectively, you must understand your targets and resolution. Some digital manometers come with BlueTooth technology, so you can log, convert, and store your data on mobile devices.

Gas leak detectors are relatively inexpensive tools. These should NOT be confused with combustion analyzers, which are different tools altogether. You usually cannot calibrate these tools. When using a gas leak detector, the leak detection process on gas pipes is similar to the electronic leak detection process on straight-cool A/C units.

Draft gauges measure very fine pressure differentials in the combustion air zone. These may use flappers or vanes to give you data about the direction and amount of draft. Most importantly, you want to ensure that you have no backdraft. These tools take very fine measurements, so they have high resolution. Because of their high resolution, they require frequent calibration to stay accurate.

Personal (or ambient) CO monitors are also important gas and combustion tools. Carbon monoxide (CO) is odorless and colorless, and it can be deadly. To avoid CO poisoning, use one of these monitors to remain aware of the CO content in your space.

Combustion analysis has evolved a lot over the years. Today, we perform combustion analysis with a single tool. When combustion occurs, a chemical reaction occurs. Combustion analyzers determine what happens post-combustion by taking temperature and oxygen readings. However, they also account for the presence of CO, which indicates incomplete combustion.

Bill and Bryan also discuss:

Analog and Magnehelic manometers
BPI-1200
Precision
CO monitor upkeep/disposal
Perfect combustion
AHRI-1260
Nitric oxide filters

0:00.0	and This episode of the HVAC School podcast is made possible by our fantastic sponsors.
0:21.2	Starting with Field Peace at Field Piece.com,
0:24.2	making all kinds of instruments and vacuum pumps
0:27.6	and recovery machines and all kinds of great stuff.
0:29.4	I'm sure you know Field Peace,
0:31.0	but it may have slipped my mind.
0:32.4	I may have never mentioned to you that my first meter in the trade was a Field Piece Meter.
0:38.0	So there you go. First Meter in the Trade Field Piece Meter. In fact, I still have a Field Piece in my van right now. I've used
0:44.8	Field Piece for many years and I especially like the VP 85 and MR 45 vacuum pumps and recovery machines.
0:50.8	Also, Air Oasis at airoasis.com, Navac Global.com,
0:56.8	makers of all kinds of stuff, all kinds of interesting tools for the HVC industry.
1:01.6	If you haven't looked at Navac yet yet I would encourage you to go to true
1:03.7	tech tools. Take a look at the navac tools and you can always get an 8% discount by using the offer code
1:09.0	get schooled. Also refrigeration technologies at refrige tech.com they make the viper cleaners and one thing that I love about viper cleaners is that they do the job but without nasty chemicals.
1:19.0	You can tell the first time you use viper that it just doesn't have that nasty punch that some of the other chemicals have and if you get a little bit of it on you for most of the products it's not going to be nearly as damaging as what a lot of the other competitors have out there.
1:31.3	So find out more by going to Refrigeech.com. And then finally,
1:35.2	our longest sponsor, the sponsor who stuck with us from the very beginning and really truly
1:38.9	made this podcast possible all the way from the start carrier and carrier dot com
1:47.0	Every man hits a certain stage in life, a stage where they become more serious.
1:55.0	This guy blew right past that stage straight to old man dad humor.
2:00.0	Brian Oar.
2:02.0	All right, Haiti, Heidi, Heidi, Heidi, haughty. I probably overdo the Haiti, Heidi Highty Hody thing.
