Well, I've got two of these and they generally start/stop simultaneously. So there's a fair amount of noise from the gas burners. I suppose the trade-off is that they heat the tanks rapidly. There in a basement and we really don't hear much. NS
You can find the parts list for that unit at the link below. It appears that you are looking for the gas control box, which is part # 11. The current part number for it is 9003407105. http://www.hotwater.com/lit/partslists/185080-000.pdf
The only other potential problem we can think of is that there is an issue with the incoming gas line.
Can't answer the first question and suggest that you have your plumber inspect the installation. These are warranted for 6 years as I recall. The second question sounds familiar as I have experienced somewhat the same thing. I should say that I have dual-tank installation as I have a gang of women in this house. They can use up hot water very fast in the morning. I don't think these tanks come with a top-notch thermostat or are well insulated for that matter, so resting overnight does let the tank water cool somewhat. It does recover pretty well given some time. These heaters are inexpensive and thus not the highest quality you can buy. They're contractor grade and are a good value for the price (I bought 2 from PEX for ~$750 shipped). I'm selling my house so I didn't want to invest more money in something that I would not be around to enjoy. Hope this helps. NS
The thermocouple is only available as part of the pilot assembly, which is part 9003542005 for this water heater.
