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.
It is a good idea to replace all of the light bulbs at one time if they are close to the end of
their rated life. Group replacement will reduce the number of times you need to open
the unit to replace the light bulbs.
