Well got my guts up to set the fan to auto, and set to furnace at 87 degrees ( since it is at least 85 here now but without the propane on and the fan ran just fine. When I selected off from the A/C console the fan ran for about 2 minutes then shut down- so that's out of the way. Will run on propane tomorrow to burn off fumes.
Now the only pending question is the switch below the converter, and by the process of elimination, it must be for the water pump. Will fill the reserve tank tomorrow and flip that switch to try it out.
Sure would be nice if FR would make just a little quickie start up paper to address these things. I have a ton of paperwork, but have to hunt for answers everywhere. The manual they included pictures a pop-up camper! not my A-frame.
