4.4. Gas Connection

IMPORTANT: Gas connections must be performed by a qualified professional in accordance with local codes and regulations.

1. Connect the natural gas supply line to the heater's gas inlet.
2. Use appropriate gas-rated sealant on all threaded connections.
3. After connection, check all gas fittings for leaks using a non-corrosive leak detection solution. Never use an open flame to check for leaks.

5. Operating Instructions

The heater features a push-button piezo ignition system and a thermostat control for adjusting heat output.

5.1. Initial Lighting (First Use)

1. Ensure the gas supply valve to the heater is open.
2. Locate the control knob on the heater. Turn it to the "PILOT" position.
3. Press and hold the control knob in while simultaneously pressing the IGNITOR button repeatedly until the pilot flame ignites. You should see a small flame at the pilot burner.
4. Continue to hold the control knob in for approximately 30-60 seconds after the pilot ignites to allow the thermocouple to heat up.
5. Release the control knob. If the pilot flame extinguishes, repeat steps 2-4.

5.2. Turning On the Main Burner

1. Once the pilot flame is stable, turn the control knob from the "PILOT" position to the desired heat setting (e.g., 1, 2, 3, 4, 5 or High/Medium/Low). The main burner should ignite.
2. The heater offers 5 variable heat settings via the thermostat control, allowing you to adjust the heat output to your comfort level.

5.3. Adjusting Heat Output

Rotate the control knob to select a higher or lower heat setting. The thermostat will automatically regulate the burner to maintain the set temperature.

5.4. Turning Off the Heater

1. To turn off the main burner, turn the control knob to the "PILOT" position. The main burner will extinguish, but the pilot flame will remain lit.
2. To completely turn off the heater (including the pilot), turn the control knob to the "OFF" position. It is recommended to also close the manual gas shut-off valve for extended periods of non-use.

6. Maintenance

Regular maintenance ensures safe and efficient operation of your heater.

• Cleaning: Keep the heater area clear and free from combustible materials, dust, and debris. Use a soft, dry cloth to clean the exterior surfaces. Do not use abrasive cleaners or solvents.
• Pilot and Burner Inspection: Periodically inspect the pilot and main burner flames. The pilot flame should be steady and blue. The main burner flames should also be predominantly blue with some yellow tips. Any significant changes in flame appearance may indicate a need for professional service.
• Ventilation: Ensure that any ventilation openings in the room are not obstructed.
• Annual Inspection: It is recommended to have the heater inspected annually by a qualified service technician.

7. Troubleshooting

Before calling for service, review the following common issues and solutions:

• Heater does not light:
  - Ensure the gas supply valve is fully open.
  - Check if the pilot light is lit. If not, follow the initial lighting instructions.
  - Verify that the control knob is set to the PILOT position and held long enough for the thermocouple to heat.
  - Check for proper gas pressure.
• Pilot light will not stay lit:
  - Ensure the control knob is held in for the recommended time after ignition.
  - The thermocouple may be dirty or faulty. Contact a qualified technician.
  - The ODS system may have activated due to low oxygen. Ventilate the area and try again.
• Main burner does not ignite after pilot is lit:
  - Ensure the control knob is turned to an ON position (e.g., 1-5).
  - There may be an issue with the main burner orifice or gas flow. Contact a qualified technician.
• Heater produces an unusual odor:
  - A slight odor may be present during initial use as manufacturing oils burn off. If the odor persists or is strong, turn off the heater and gas supply, then contact a qualified technician.
