LightBulbReplacement
Allow at least ve (5) minutes for light bulbs to cool before
touching bulbs to avoid accidental burning of skin.
Light bulbs need to be replaced when you notice a dark
section of the ame or when the clarity and detail of the log
ember bed exterior disappears. There are four (4) bulbs
under the log set, which generate the ames and embers,
and two (2) bulbs above the log that illuminate the log
exterior.
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. Care must be taken when removing the
log set as the log set contains LED’s and wires.
LowerLightBulbRequirements
Quantity of four (4) clear chandelier or candelabra bulbs with
an E-12 (small) socket base, 60 Watt rating. Example: GE
60BC or Philips 60 CTC.

1. Disconnect power to fireplace.
2. Slide fireplace out from mantel.
3. Open the bi-fold doors and steel curtain.
4. Pull the front edge of the plastic ember bed or plastic
grate up and forward until the rear tab releases from the

!NOTE:Log set ts tightly into rebox, some force may
be necessary to remove.
5. Set log set in front of replace.
6. Disconnect the log set LED wire harness from unit
(Figure 5).
7. Pull the Flicker Rod to the far right, then bend it carefully
to free and lift the left side out of the mounting bracket.
! NOTE: When removing the Flicker Rod, damage may
occur if bent excessively. If the Flicker Rod is damaged,
replace to insure proper operation.
8. Replace bulb(s) as needed.
9. Reinstall the Flicker Rod.
10. Reconnect the log set LED wire harness.
11. Replace the log set by inserting the rear edge of the log
set and push down on the front edge of the ember bed
until it snaps into place (Figure 6).
!NOTE:Ensure the log set is installed tightly under the
back ledge to prevent light leakage.

avoid accidental burning of skin.
Disconnect power before attempting any maintenance or
cleaning to reduce the risk of electric shock or damage to
persons.
ReplacementProcedure
1. Slide fireplace out from mantel.
!NOTE:Use caution when removing bottom panel as
there are components attached to the panel which are
hard wired within the replace chassis.
!NOTE:The bi-fold doors are supported by the bottom
panel. When pulling the bottom panel away from the
chassis, do so carefully so that the doors do not get
damaged.
4. Carefully remove bottom panel from replace and swivel
it outwards to the right so as to keep wiring connected
but allowing sufcient room to work.
5. Slide the bi-fold doors out of the top frame track and set
aside.
6. Disconnect the log set LED wire harness.
7. Remove the six (6) Philips screws that hold the log set
support bracket in place. Refer to Figure 10 for a side
view of the replace showing screw locations.
!NOTE:Some replaces have these three points riveted
instead of screwed in place. If this is the case, use a 1/8
inch drill bit to drill out the rivet.

screws on each side along the top edge; and two (2)
screws on the back along the top edge (Figure 12).
replace. Slide the bracket directly out the bottom of the
replace and set aside.
10. Slide Mirror down and out the bottom of the replace.
11. Align sides of replacement Mirror with grooves of rubber
extrusions and with brick effect facing out towards the
front of the replace, slide Mirror up into the replace.
The Mirror should slide into a holding track just beneath
the lter.
12. Slide Log Set Support Bracket back into place, the sides
of the bracket lining up with the grooves of the rubber
extrusions (Figure 11).
13. Reinstall Log Set while support bracket is loose within
replace. The back edge of the Log Set should t under
the bottom edge of the Mirror, and the front edge of the
Log Set should t in behind the top, inside edge of the
Log Set Support Bracket (see Figure 6, page 8).
14. Install Log Set Support Bracket using the six (6) screws
from step 7 (or, if rivets were originally in place, use the
screws supplied with RP kit for Mirror).
15. Reconnect the LED Wire Harness for the Log Set.
16. Reassemble the bottom panel of the replace following
steps 1-5 in reverse order.
