Burning out the coil can and will happen over time, and there are ways to extend the life span of the coil inside the cartridge, but again this will just happen over time with use.
Make sure never to fire the device without enough liquid inside the cartridge.
Prevent the coil from overheating too much from frequent use by just allowing some time between puffs. If you take puffs too quickly back to back, the coil can get rather hot, and you risk burning out the coil.
Make sure that you are not taking too long of a puff because this can also easily overheat the coil causing it to burn.
One last tip would be to make sure that the airflow control valve, which can be found just below the mouthpiece, is fully open so that you can allow the proper air to flow over the hot coils if this is closed when you go to fire the device you will starve the coil of the much needed cool air.
