If unit was operating prior to servicing allow at least 10 minutes for light bulbs and
heating element to cool off to avoid accidental burning of skin.

electric shock or damage to persons.
Light bulbs need to be replaced when you notice a dark section of the flame. There are
four bulbs under the log set which generate the flames and embers.

the unit to replace the light bulbs.
