Why is my Dimplex DF2550 Indoor Fireplace making excessive noise when the heater is on?

If there is excessive noise when the heater is on in your Dimplex Indoor Fireplace, it could be due to a dirty Heater Assembly. Ensure that the exterior intake louvers and firebox cavity are free of dirt and dust. Another possibility is a defective Heater Assembly, which would need to be replaced.
