Remember I attributed my problems to greed and stupidity. I purposely had adjusted my draft to .02. I run my combustion fan 24/7. Keeps the chimney warm and holds a pretty steady draft. I've been running it this way for a good part of this cold season.
When the stuff hit the fan here Tuesday evening and I determined there was a real CO event, I went into immediate shut down and ventilation mode. No real diagnostics or observations made. I guess I went tactical instead of scientific. In doing so I lost maybe some valuable information. I've never had the CO detectors in my home go off other than the first day I fired the boiler and had no restrictor plate on the combustion fan. That overpressurized the combustion chamber and caused flue gaes to be expelled out of the hopper too.
I just pushed the limits alittle to far. Fortunately I have backup for my backup when it comes to CO protection. I appreciate all the well wishes that I'm still on the green side ( or white side now) of the earth but we were never in any danger due to the CO protection we have installed. No substitute for having current model detectors with good interconnected power source and fresh batteries. An early warning throughout the house is essential.
