If the fireplace insert is registering an E3 code, it simply means that the heater is not working. An E3 code may appear on both new and used units, but there are some steps you can take to correct this.
- It is important to allow the insert to acclimate to its new environment. Regardless of the time of year you've purchased the unit, the temperature inside your home is different from the temperatures of the factory, warehouse, and any other spot along the journey. Allowing it to settle in for 24-48 hours before plugging it in is a best practice for smooth operation.
- Unplug the fireplace insert between uses.
- Do not overload the circuit. Do not plug any other items into the same outlet as the fireplace insert, as it draws a significant amount of power.
- Ensure that the connection between the plug and outlet is tight. A loose outlet will draw too much power, resulting in an error code.
- Only plug the power cord directly into the outlet and NEVER use an extension cord or surge protector.
In addition to the points mentioned above, also check the vents for dirt or clogs. Unplug the unit and clean any dust or debris from the vent area. Leave the fireplace insert unplugged for 24-48 hours, plug the power back in and turn on the heater.
