Dag, thanks. Pretty rude of Mari to dig up what was obviously a very difficult time in your life to make a very weak point/slam. Where's the compassion???
RS - you accept what Mari tells you as the truth, I do not. Thus, the difference in our opinions. Maybe if you read more than a thread or 2 here and there (as you told the AG'ers several times) you'd have a different opinion - maybe not, doesn't matter to me either way.
CO detectors do not replace the need to have your fuel-burning appliances serviced, by professionals, especially when you know they are faulty. And Mari claims she had one... but thanks for the PSA.
