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.
Disconnect power before attempting any maintenance or cleaning to reduce the risk of
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.
LOWER BULB REPLACEMENT
1. Remove the trim by turning the retaining fasteners counter clockwise ¼ turn until the
trim releases from the firebox using a slotted screwdriver. (FIGURE 1)
2. Hold the glass in place while removing the retaining clip from the upper center of the
firebox.
3. Lift glass out and store in a safe place.
4. Lift up the front edge of the log until it clears the front tabs. Pull out until the rear tab
clears the back ledge, then lift out.
5. Examine the bulbs to determine which bulbs require replacement.
6. Hold the socket while unscrewing the bulb.
7. Hold the socket while screwing in the new bulb.
8. Replace the log emberbed by placing the back lip of the log emberbed under the
mirror then push the front of the log emberbed down into the recess.
LOWER LIGHT BULB REQUIREMENTS
