Nice description of the picture (chandelier), Jim.
My folks have had a setup like Jon's since just before the Y2K scare. Mom was sure they would be out of power for weeks. Of course it didn't happen but the generator came in handy now and then.
We had been trying to get the guy who originally installed it to move it away from the house but he kept stalling. It was located under the window to my Dad's bedroom and he could smell the exhaust each time it came on for the test run or when the power had gone out. I spoke to the installer myself after Hurricane Irene and he kind of looked at me like I was paranoid but agreed that he would do it.
More than one year later, after a few days of the generator being on after Hurricane Sandy, the carbon monoxide alarms in the house went off. I put boards up over the windows and wall near it and it ran for another couple days before finally dying. It was over revving, eventually shutting down and could not be fixed. One company came out near midnight and worked for 45 minutes or more on it but ultimately gave up, said the part needed was not available since it was too old. (Would you believe they didn't charge anything? Just apologized for not fixing it and left. Amazing!) The original guy installed a new one and turned it 90ª so the exhaust was not going toward house. Two days later, carbon monoxide again so we shut it off. 'Fortunately' the power came back after day 12.
We insisted he move it this time and it is now located up next to the propane tank about 35 feet from the house where it should have been in the first place. My folks had a yearly maintenance agreement with this guy for 12 years but suffice to say we don't have one with him now. It is important to check the oil and battery regularly, though as the test runs each week do make these things subject to eventual failure if not maintained.
