Come guys it was only up to 80ppm.........but I figured out the problem.........the dummy
that installed this boiler had not emptied out the fines for quite a while
and as I was reading the instructions for my new CO meter it said something about lack of air for combustion. As that rolled around in my brain after turning up the air
it hit me it doesn't matter how much air I give it, it won't do any good because the air is blocked by the fines. So I aired out the house and the meter says 16 PPM's which matches the outside. Thanks guys for all your help.
