MAINTENANCE
 WARNING: Disconnect power before attempting
any maintenance or cleaning to reduce the risk of re,
electric shock or damage to persons.
CAUTION: Allow at least ve (5) minutes for the light
bulbs to cool before touching them to avoid accidental
burning of the skin.
Light Bulb Replacement
Light bulbs need to be replaced when you notice a dark
section of the ame or when the clarity and detail of the
log exterior disappears. There are four (4) bulbs under the
log set which generate the ames and embers and two (2)
bulbs up, in behind the grille, that illuminate the interior of
the replace.
Required Tools: Phillips #2 screw driver, Slot screw driver.
Approximate time: 15 minutes to change upper and lower
light bulbs.
Helpful Hints: It is a good idea to replace all 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 light bulbs.
To open the light bulb area:
Remove the trim by turning the retaining fasteners1.
counterclockwise 1/4 turn until the trim releases from
the rebox using a slotted screwdriver (Figure 5).
Hold the glass in place while removing the retaining clip2.
from the upper center of the rebox (Figure 6A, B).
Lift glass out and store in a safe place.3.
Lower Light Bulb Requirements
Quantity of four (4) clear chandelier or candelabra bulbs
with an E-12 (small) socket base, 60 Watt rating.
To replace the bottom light bulbs:
Lift up the front edge of the log until it clears the front1.
tabs. Pull out until the rear tab clears the back ledge,
then lift out (Figure 7).
Examine the bulbs to determine which bulbs require2.
replacement.
Hold the socket while unscrewing the bulb.3.
Hold the socket while screwing in the new bulb.4.
Replace the log ember bed by placing the back lip of5.
the log ember bed under the partially reective glass
then push the front of the log ember bed down into the
recess (Figure 7).
Upper Light Bulb Requirements
Quantity of two (2) clear chandelier or candelabra bulbs
with an E-12 (small) socket base, 15 Watt rating.
To replace the top light bulbs:
Locate the two upper bulbs inside the rebox at the top 1.
(Figure 8).
Examine the bulbs to determine which bulbs require2.
replacement.
Hold the socket while unscrewing the bulb.3.
Hold the socket while screwing in the new bulb.4.
Glass Cleaning
The glass is cleaned in the factory during the assembly
operation. During shipment, installation, handling, etc., the
clear door may collect dust particles, these can be removed
by dusting lightly with a clean dry cloth.
To remove ngerprints or other marks, the clear door can
be cleaned with a damp cloth. The clear door should be
completely dried with a lint free cloth to prevent water
spots. To prevent scratching, do not use abrasive cleaners
or spray liquids on the clear door surface.
Fireplace Surface Cleaning
Use a cloth dampened with warm water only to clean
painted surfaces of the electric replace. Do not use
abrasive cleaners.
