I started typing this as a question, wondering who else might check but instead rewrote as a heads up..
That said if you want to add to this, please reply..
In a previous life I installed many oil and gas boilers. I always commissioned the equipment as per manuf. install instructions...
In a less previous life I did combustion safety testing on equipment to make sure of proper function before any building shell work was performed and also tested new houses at final..
Im no stranger to verifying #2 smoke or less and making sure the CO is within acceptable range.
I personally have tested brand new gas fired boilers above 2,000 PPM CO. I have seen Oil systems pushing 400 PPM.
Typically in undiluted flue gases we expect LP/NG to be under 100PPM and oil to be under 50 PPM
Now, Im a code official. Im blown away with the lack of knowledge many contractors actually have as far as this goes...
I have found 98% of new installs not tested. I have found 80% of existing systems never tested.
I find at least in my jurisdiction this is considered special knowledge...
The testing location on an oil boiler (needs to be between the boiler and barometric damper).
Many Gas fired boilers have ports by the manuf, but I have never seen this on natural draft equipment...
We all know the PMC requires the owner to maintain the mechanical equipment. My word of advice, a reciept of service is NOT enough.
Inspect the flue to be sure there is evidence of proper commisioning.
Almost ALL burner, boiler and testing equipment manuals specify a holde to be drilled in the flue below the damper.
I can bet you a BEER you will find almost ALL equipment has never been checked !
