An important line of defense for the ones you loveThis is of particular concern to me. Several years ago I lost a friend to (CO) cxarbon monoxide. This was a needless loss. I had warned him about the danger and he ignored me. It cost him his life. I was not in the Heating bussiness at that time, but now I am and it is something I take very seriously. I test for any carbon monoxide in the living area and I use an exhaust gas analyzer to check the efficiency on the gas combustion. By code you are allowed 300 parts per million of CO in the exhaust. With proper adjustment the exhaust should be less tha 50 PPM. I recently checked a new customers furnace and the exhaust was over 2000 PPM. I cleaned the burners and adjusted the flame and got the exhaust down below 50 PPM. If the furnace happens to develop a crack in the heat exchanger you have a lot better chance of living long enough to figure out what is going on if the combustion is clean.Not too long ago, carbon monoxide detectors were only for people who had sophisticated alarm systems in their homes. Today most every family is aware of the dangers of carbon monoxide poisoning and have at least one CO detector in their home. The smartest families have CO detectors installed on every level of their home, including one next to their heating equipment. This is the safest way to protect your family from deadly carbon monoxide poisoning.
