  Phillips head screw driver 

Small cutter or snips

  CAUTION: 

Follow “Preparation for Service” instructions 

before proceeding.

Remove the lower face panel.  5 screws in total are 

1. 

holding the panel. 3 are located underneath the front 

face, and 2 screws are (1) on the  left and (1) on the 

right, inside the unit. 
If the electrical junction box cover was not removed 

2. 

during the Removal Preparation steps, then remove the 

electrical junction box cover located on the bottom right 

hand side by removing the 1 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 manual control 

4. 

switches, 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. (One connects the red wire to the black/

orange wire; and the other connects the yellow wire to 

the solid black wire).    

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. 
Tuck 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 

13. 

using the 2 orange wire connectors from STEP 6. (One 

connects the red wire to the black/orange wire; and the 

other connects the yellow wire to the solid black wire).
Tuck wires back into control panel area.

14. 

Reassemble in the reverse order as above.

LED DRIVER BOARD REPLACEMENT

Tools required:

 Phillips head screw driver

Needle nosed pliers

Small cutter or snips

  CAUTION: 

Follow “Preparation for Service” instructions 

before proceeding.

On the top right side, just below the manual control 

1. 

switches, 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.
Remove the two (2) cable ties on the right to allow ac-

2. 

cess to the wires of the LED panel.
On the LED driver board (smaller board on the right), 

3. 

remove the two (2) orange wire connectors and sepa-

rate the wires. (One connects the red wire to the black/

orange wire; and the other connects the yellow wire to 

the solid black wire
On the same LED driver board remove the 2 wire con-

4. 

nectors that join the 2 white wires together and the two 

black wires together.
To remove the board off the 4 plastic mounts, it may 

5. 

be done in one of two ways.  If new mounts are sup-

plied with the board, cut the old mounts off at the LED 

driver board.  Pull the old board off.  Slightly raise the 

top of the firebox off your flat surface and push the old 

mounts out towards the back.  Insert and push the new 

mounts from the backside of the fireplace into the back 

panel Line up the holes on the 4 corners of the LED 

driver board and press the new board onto the mounts.  

Make sure the board is secure. 
Reassemble in the reverse order as above.

FLICKER MOTOR/FLICKER ROD 

REPLACEMENT

Tools required:

  Phillips head screw driver.  

  CAUTION: 

Follow “Preparation for Service” instructions 

before proceeding.

Partially release the lower face panel.  Release (1) 

1. 

screw on the left side and (1) 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.
