Is this true about c02

Low Carbon Monoxide Risk
Carbon Monoxide (CO) is an odorless and colorless gas that is the by-product of combustion of any carbon-based fuel and which can pose serious health risks. Oil, coal, wood, propane and natural gas all emit CO and when functioning properly all heating units are safe. Nevertheless, in the event that a malfunction occurs, oil heat units will emit smoke prior to accumulating dangerous levels of CO. Naturally, this serves as a warning sign. When a natural gas or propane burner malfunctions, however, it will emit dangerous levels of CO before a smoke build-up.

It is my understanding...

... that oil-fired systems can produce carbon monoxide with or without the presence of smoke. I would not rely on zero smoke to convince me that the combustion is set up well. The only way to know is to test.

zero smoke CO !!!

Years ago I did some testing to see how differant settings would effect an oil boiler .

I had the boiler running with zero smoke and 1,200 PPM CO !!!
Don't just rely on the zero smoke on setting up an oil boiler.

All Carbon based fuels , All !! will generate large amounts of CO if not set up correctly.

False


Oil can produce high CO with no smoke. I've seen it happen.

I too have seen high monoxide with zero smoke. A combustion analyzer is the only way to insure proper set-up and combustion. Is it possible to have low/no C/O and smoke??

the secret weapon

They're using calibrated smoke! Don't you have your color cards that work like a smoke number only for CO?
