@DellAquila thank you very much for that info.
@Bronzeborg - Yes if you open the zip file, you will see a file called "control.lua". I simply renamed it to "control.lua.old". One thing to note, you have to make sure you do not have and big furnaces in place. If you delete the furnace after you make the change to the file, you can not remove the loaders. So here is the steps I took.
Removed all of my big furnaces.
Saved map and exit the game.
Open the file TheBigFurnace_0.0.5.zip located in C:\Users(your user name)\AppData\Roaming\Factorio\mods. I used Winrar to open it.
Go into the big furnace folder, rename control.lua -> control.lua.old
Exit the zip program.
Relaunch Factorio and load your map.
