6. Uputstvo za upotrebu
6.1 Initial Ignition
- Provjerite je li ventil za dovod plina otvoren.
- Insert the included AAA battery into the Piezo ignition unit.
- Turn the control knob to the 'Pilot' position and depress it.
- While holding the knob down, press the Piezo ignitor button repeatedly until the pilot flame ignites. Continue to hold the control knob down for approximately 30-60 seconds after ignition to allow the thermocouple to heat up.
- Release the control knob. If the pilot flame extinguishes, repeat the process.
6.2 Main Burner Operation (Thermostat Control)
The thermostat control allows you to set a desired room temperature, and the unit will automatically cycle on and off to maintain it.
- Once the pilot is lit, turn the control knob from 'Pilot' to the desired heat setting (1-5).
- The main burner will ignite, and flames will appear among the logs.
- To adjust the temperature, rotate the control knob to a higher or lower setting. The unit will automatically regulate the flame to reach and maintain the set temperature.
- To turn off the main burner while keeping the pilot lit, turn the control knob to the 'Pilot' position.
- To completely turn off the unit, turn the control knob to the 'Off' position and close the main gas supply valve.

7. Održavanje
Regular maintenance ensures safe and efficient operation of your fireplace logs set.
- Godišnja inspekcija: Have a qualified service technician inspect the burner assembly, gas connections, and logs annually.
- čišćenje: Keep the area around the appliance clear of combustible materials. Periodically clean the logs and burner area with a soft brush or vacuum cleaner to remove dust and debris. Ensure the unit is completely cool and the gas supply is off before cleaning.
- Stanje zapisnika: Inspect logs for cracks or damage. Replace any damaged logs to maintain proper flame patterns and safety.
8. Otkrivanje problema
If you encounter issues, refer to the following common troubleshooting steps. For persistent problems, contact a qualified service technician.
8.1 Pilot Light Will Not Stay Lit
- Snabdijevanje plinom: Ensure the main gas supply valve is fully open.
- termopar: The thermocouple may not be heating sufficiently. Ensure the pilot flame is directly impinging on the thermocouple. Hold the control knob down for the recommended 30-60 seconds after ignition.
- ODS Activation: The Oxygen Depletion Sensor may have activated due to low oxygen levels. Ensure adequate ventilation in the room.
- Pilot Orifice: A clogged pilot orifice can cause a weak pilot flame. This requires professional cleaning.
8.2 Main Burner Does Not Ignite
- Pilot Lit: Confirm the pilot light is actively burning. The main burner will not ignite if the pilot is out.
- Control Knob Position: Ensure the control knob is turned to a numbered heat setting (1-5) and not just 'Pilot' or 'Off'.
- Pritisak plina: Low gas pressure can prevent the main burner from igniting. Consult your gas supplier or a professional.
