Dust and debris on the coils can potentially create a fire hazard, which is why it needs to be immediately removed. However, this will mean taking off the safety grate that covers them. First, you need to make sure that the fireplace is off and not plugged in. Then, you will need to remove the screws that hold them in place. After you do this, it's important to clean them with a cloth that is completely dry and will not leave any lint behind. Not only is this essential for preventing fires, but it's also a crucial part of optimizing the energy efficiency of your fireplace.
