LED LIgHT STRIPS REPLACEMENT
WARNINg: Disconnect power before attempting any
maintenance or cleaning to reduce the risk of electric
shock or damage to persons.
CAUTION: If unit was operating prior to servicing allow
at least 10 minutes for lights and heating elements to cool
off to avoid accidental burning of skin.
Tools required: Phillips head screwdriver
Wire snips
CAUTION: Follow “Preparation for Service” instructions
before proceeding.
Partially release the lower face panel, by removing 1.
the screw on the left side and on the right side of the
panel, inside the unit. Pull the front panel forward from
the topside by approximately 2” inches. There are 3
additional screws located underneath the front face but
do not need to be removed. There should be enough
“give” to allow the panel to pull slightly forward.
! NOTE: If the 3 bottom screws to the front panel are
accessible in your application, you can remove them to
obtain the most clearance for the repair. If they are not ac-
cessible, you can still proceed with them attached.
Remove the electrical junction box cover located on the 2.
bottom right hand side by removing the screw on the
front of the cover. Lift the cover out and set aside.
Remove the flicker rod by slightly bending the rod and
3.
pulling the rubber bushing off the motor arm located on
the bottom right. Remove the middle plastic bushing
by lifting it up off the center bracket. Slide the remain-
der of the flicker rod off the end bracket on the left.
CAUTION: When removing and replacing the flicker
motor try to keep any slight bending of the flicker rod
minimal so as to not damage it. If flicker rod is damaged, it
should be replaced to ensure proper operation.
On the top right side, just below the Remote Switch- 4.
board, remove the 2 screws that secure the upper
control panel cover. Remove the cover and set aside
to allow access to the LED Driver Board wires.
On the LED Driver Board (smaller board on the right),
5.
remove the two (2) orange wire connectors and sepa-
rate the wires - noting original configuration.
In the lower area of the fireplace, remove the 2 screws
6.
on each LED light strip, which secure the strips to the
light strip covers.
Cut and remove plastic cable ties that hold the wires in
7.
place from the LED light cover at the bottom and up to
the LED Driver Board at the top.
Gently pull the LED light strip wires up and around from
8.
the side of the light covers to free the strips. The cov-
ers may require a small amount of pressure upward, to
allow a little “give” when feeding the wires around the
covers.
Lift and remove LED strips out of the light covers and
9.
slide the wires out of the protective insulation.
Feed the wires from the new LED strip back through
10.
the same protective insulation up to the LED Driver
Board.
Attach the new LED strips to the LED cover with the
11.
screws from step 9.
Route wires around the light covers and re-attach the
12.
covers with the screws from the outer bottom panel of
the fireplace.
Reconnect the wires at the LED Driver Board at the top
