@RJT posted:Found the removable Steam Dome primed the whistle smoke unit but can't seemed to get it turned on. No information in the downloaded MTH Manual looked at my Big Boy Manual and tried the softly feature of selecting the "SPW" key and then the "FSW" key but that does not seem to work. It is like there is one step missing. With both keys highlighted the whistle will not work and depressing the keys a second time removes the highlighting but still no whistle smoke. I am confused!!!! HELP!!!
The Steaming whistle is a small smoke unit with single resistor. Thus be careful to not overfill it compared to the normal main stack unit.
That unit also does not have a large fan impeller and so because steaming whistle has a small tube path for the smoke it exit, often may get a smoke fluid drop blocking the path that the fan is not strong enough to just blow past and out.
As such, it's recommended to check for function by holding the fill cover off since smoke can then flow out of the larger hole. Test and get it to smoke this way first, then attempt to clear the blockage in the smaller exit hole path for the whistle
Also, you may need to toggle the FSW (steaming whistle on and off a few times) to ensure it actually turns on. I know that is crazy and annoying, but that was my personal experience with the 2 heavy pacifics I also own.
