Troubleshooting the flame effect

Step-by-step repair procedure



Disassembly
- Unplug: Disconnect the fireplace from the wall outlet and move it away from the wall to access the rear of the unit.
- Loosen locknuts: Use a Phillips head screwdriver to turn the eight locknuts on the inner and outer walls counterclockwise.
- Remove top panel: With assistance, lift off the top panel and place it upside down on a clean, scratch-free surface. Be careful not to bend the connecting rods.
- Remove brick panel: Slide the middle brick panel upward out of its routed channel and set it aside.
Repair
- Connect USB: Locate the USB cable attached to the heater assembly. Pass the cable through the round hole at the lower left side of the metal base, then connect it to the bottom left corner of the log set assembly. Use the included twist tie to secure excess wiring to prevent it from getting caught or pulled loose.
- Test: Plug the fireplace back into the wall outlet. Turn on the power and adjust the flame using the Flame Brightness icon. If the flame operates correctly, proceed to reassembly.
Reassembly
- Reinsert brick panel: Ensure the unit is unplugged for safety. Slide the middle brick panel downward into the routed channel.
- Secure top panel: With assistance, place the top panel back onto the mantel, aligning the pins and dowels. Use a Phillips head screwdriver to turn the eight locknuts clockwise to secure the top in place.
