The Covenant 36" Electric RV Fireplace remote control does not require pairing, but it operates via infrared (IR) and depends on several factors for proper functionality. First, ensure the rocker switch on the fireplace itself is turned ON, as the remote won't work if the fireplace power is off. The remote must have a clear line of sight to the fireplace's IR sensor, with no obstructions, and should be used within 8 to 10 feet. Verify that the battery is installed correctly in the remote. If the fireplace responds to its built-in control panel but not the remote after these checks, the remote may be faulty. In that case, providing a photo of the powered-on fireplace can help facilitate a replacement remote. For further technical assistance, contacting Lippert Customer Service Tech Team is recommended.
