8. Troubleshooting
If you experience issues with your log set, refer to the following common problems and solutions. For persistent issues, contact a qualified service technician.
- Unit does not ignite: Check if the gas supply is on. Ensure the AAA battery in the Piezo ignitor is fresh and correctly installed. Verify the pilot light procedure is followed correctly.
- Pilot light will not stay lit: Ensure the control knob is held down long enough after pilot ignition (30-60 seconds) to heat the thermocouple. Check for drafts or blockages around the pilot assembly.
- Main burner does not ignite: Ensure the pilot light is lit. Check that the control knob is turned to a heat setting beyond the PILOT position.
- Unit shuts off unexpectedly: This may indicate the ODS system has activated due to low oxygen levels. Ensure adequate ventilation in the room. Do not operate the unit in unventilated spaces.
- Unusual odors: A slight odor may be present during the first few uses as manufacturing oils burn off. If strong or persistent odors occur, shut off the unit and ventilate the area, then contact a service technician.
