I've removed a couple of features in order to keep the script dialog from being too big (it's already big enough). One of these features is setting the speed of the animation (it automatically assigns 41 ms to each frame.) You can manually change the timing or use saulgoode's Animation Settings script found elsewhere on this forum.
If you had the previous Animated Fire script installed, please delete it.
Copy GIMPressionist presets to your GIMP Gimpressionist Presets Folder (ie..C:\Documents and Settings\username\.gimp-2.6\gimpressionist\Presets)
Copy script (.scm file) to your GIMP scripts folder (ie.. C:\Documents and Settings\username\.gimp-2.6\scripts)
Refresh your scripts (Filters > Script-Fu > Refresh Scripts)
Run the script (Filters > Animation > Animated Fire....)
Here's some sample previews of the new script:
