Joined this site so I could become a member of the club. Purchased a LPG BFG1F5040T3PV in April 2008, worked fine until this weekend. Water Heater is the US CraftMaster version. Previous heater was American Standard, same manufacture just different brand, and had worked fine just was getting old, so purchased without reading. Really mad at self because I could have got a Bradford at same price. Anyway, reason I quoted this post is that I have done the same thing (installed Old Control Valve In Water Heater) because I didn't want to be without hot water for 2 days while new LPG control value is shipped. Don't know why but the valve is being shipped overnight at no cost and they even gave me a number to call for free installation. If I install the new valve I will do it myself as the installer is A & E Sears, and the reports on them are not that good. And installing the control valve/thermostat is not that hard.
Only thing I see that I am not getting with the old control valve is not having the thermal switch on the thermocouple, which may be a good thing. When I bought the new water heater it came with the skirt and it appears to do a good job as the screen on the bottom was clean.
Will not spend any money on this water heater and when it fails again will probably replace.
