3.4 Log Set Placement
This burner requires an Empire "LS" log set of the same size (24-inch) for optimal performance and appearance. Follow the log set manufacturer's instructions for proper placement on the burner.
4. Operating Instructions
4.1 Pilot Ignition (Standing Pilot/Piezo)
- Ensure the gas supply to the unit is open.
- Locate the control knob on the Millivolt Safety Valve.
- Push the control knob in and turn it to the "PILOT" position.
- While holding the knob in, repeatedly press the piezo igniter button until the pilot flame ignites.
- Continue to hold the control knob in for approximately 30-60 seconds after the pilot ignites to allow the thermocouple to heat up. Release the knob; the pilot should remain lit. If it extinguishes, repeat steps 3-5.
4.2 Burner Operation
- Once the pilot is lit, turn the control knob from "PILOT" to the "ON" position.
- Use the integrated on/off switch on the Millivolt Safety Valve to turn the main burner on or off.
- If a remote control or wall switch is installed, use that device to control the main burner.
4.3 Shutting Down the Burner
- Turn the main burner off using the on/off switch or remote control.
- To turn off the pilot, turn the control knob to the "OFF" position.
- For extended periods of non-use, turn off the main gas supply to the appliance.
5. Maintenance
Regular maintenance ensures safe and efficient operation of your burner.
- Annual Inspection: Have the burner and gas connections inspected annually by a qualified service technician.
- Cleaning: Keep the burner and log set free of dust and debris. Use a soft brush or vacuum cleaner. Do not use abrasive cleaners.
