Why is the flame very week or appearing on only one side?

If your flame looks very weak, uneven, or only appears on one side, this guide helps you restore a full, balanced flame effect.

In most cases, the fix is simple: clean the atomizer/mist system using the correct cleaning solution.

Clean the mist system

Turn off the fireplace and let it sit for a minute.
Use the approved cleaning solution to clean the unit (this removes residue and improves mist output).
After cleaning, refill with clean water and test the flame again.

For the correct cleaning method and maintenance frequency, follow this guide:

Remove the factory protective film (first-time use):
Some units may ship with a protective film on the atomizer/mist component. If it’s still in place, it can block mist output and cause a weak/uneven flame. Remove the film and test again.
Check installation and airflow:
Poor airflow can cause mist to drift sideways or stay low, making the flame look weak or one-sided. Make sure you have proper ventilation space around the unit.

Avoid common mistakes that reduce mist output:
Using the wrong water, reusing drained water, or adding oils/fragrances can damage the mist system and reduce flame performance.
