Fireplace Clone Help

Hi I followed a tutorial on replacing an objects tuning with sims 4 studio. I'm trying to make a fire pit cloned from a plant. After adding the fireplace tuning in the Star version of studio everything seemed ok. When in game the fireplace gets lit by the sim but no fire appears. Do I need to do more than just adding the tuning to my package? Is there any tutorials on this subject I can learn from.

I'd rather not mess with cloning from a fireplace. The lit texture drives me crazy!  

Any help is very much appreciated!
