OK.
Carbon monoxide is produced when carbon-containing materials are burned in the absence of adequate oxygen. The result of this incomplete combustion is the production of CO gas rather than CO2.

Something is amiss with your combustion air- first, you would have to have insufficient combustion air to form an appreciable amount of CO. Its usually less than 1% of exhaust gases. to get enough concentration to explode and cause damage, there would have to be serious defficiencies to block off air flow to the combustion chamber.
Then, you would have to introduce a sufficient amount of combustion air in the exhaust gases to have enough oxygen to allow combustion. I dont really have a good explanation for this without having more knowledge of your system. There could be a leak or maybe a sabateur took the combustion air pipe and moved it from the combustion chamber to the exhaust ductwork.

that could have happened anywhere.
faulty pipe lines, unusual spike in temperature, faulty material - excessive corrosion of material by flue gas components like SOx, NOx, etc.
Carbon Monoxide usually oxidizes into CO2 at boiler temperatures, so that is quite harmless.

Incomplete combustion of fuel gasses and an overheated exit flue.
Who hasnt been keeping the flues clean?

No sufficient O2 or low temperature will be more CO
