Gas Connection

Connect the appliance to the natural gas supply line. All connections must be leak-tested using a non-corrosive leak detection solution. Do not use an open flame for leak testing.

Operating Instructions

Initial Startup

1. Ensure the gas supply valve is open.
2. Press and hold the control knob to the "PILOT" position.
3. Press the Piezo igniter button repeatedly until the pilot flame ignites.
4. Continue to hold the control knob for 30-60 seconds after ignition to allow the thermocouple to heat up.
5. Release the control knob. If the pilot flame extinguishes, repeat steps 2-4.
6. Once the pilot is stable, turn the control knob to the desired heat setting (e.g., "LOW" to "HIGH" or "THERMOSTAT").

Thermostatic Control

The DLS-N24T-1 model features thermostatic control. Once the control knob is set to the thermostat position, the burner will automatically cycle on and off to maintain the desired room temperature. Adjust the knob to increase or decrease the target temperature.

• Annual Inspection: Have the appliance inspected annually by a qualified service technician.

  • Clean the ceramic logs periodically with a soft brush or vacuum cleaner to remove dust. Handle logs carefully as they are fragile.

• Pilot and Burner: Check the pilot and main burner flames periodically. They should be blue with no yellow tipping. If yellow flames are observed, contact a qualified service technician.
