[QUOTE=heatingman;25940194]I sure hope that does not mean 80 hrs work gets you 40 hours pay.

:/ wondered same

Thanks for the links!!!!!
I might just send myself. I’m always in for quality training. Most classes I’ve had have seemed much more like a sales pitch and I ONLY do service which the classes don’t...

Could you advise me in applying that information? Say I find myself in that situation and suspect duct sizing so I take measurements. I’m sure that is information you want your tech to just have -...

If there is an actual tool you would recommend for measuring this I would greatly appreciate it. I was asked if I could feel with my hand which is too subjective for me. It seemed like air flow was...

Have not currently been testing TESP - yet. But I did pull the blower and climb inside. The secondary was very clean.

Was there for almost 3 1/2 hours testing as instructed over text by my boss. After about 45 min we had 90 degrees return air; seemed high to me and I thought I have read that is not right.

I’m not sure what you mean by the 6% o2 comment?
O2 is short for Oxygen content in the flue gas sample. I thought you did a combustion analysis and knew what the numbers mean

- we really don’t....

So I’m dumb! Reading this I’m not sure - does that mean if intake is disconnected it’s not working properly? The experienced tech advised me that he pulled and needs to stay off - he says it’s still...

No zones or dampers of any kind. I crawled around to make sure nothing was disconnected, lots of flex duct that is not pulled tight. Poorly insulated 1200 sq ft lake cabin with crawl space. ...

There is a 3” combustion air vent to the outdoors; but that was removed previously and the unit pulls from the damp Michigan crawl space.

So by not t-ing, my measurement is just wrong and gas pressure maybe the issue. I would love the installers guide if you could email - I will reread.

Blower wheel clean, no obstruction in secondary or a coil. I don’t yet know how to test TESP; but this unit has been running and being used for years.
Would a static pressure issue suddenly crop up...

Dang it! No!!!
And no excuses but this was the darkest, wettest, on your stomach crawl space I spent a lot of time in. Enough time to read properly :/

I am new to the field with very little training. I am trying hard to read and research and purchase all the necessary tools. I don’t know how to test for static pressure. I read it all the time; it...
