Is it normal for the heating element in my Dimplex SF3003 Indoor Fireplace to glow red?

Small glowing sections of the heating element in your Dimplex Indoor Fireplace are considered normal. However, if larger glowing sections are causing the heater to trip the thermal cutout, unplug the unit, discontinue use, and replace the heater assembly.
