3. Setup and Installation

Installation of the Fagor FE-11D PLUS/1 N water heater requires adherence to specific technical and safety standards. It is mandatory that installation is performed by a licensed professional.

3.1. Site Selection

• Install in a dry, frost-free area, protected from direct sunlight and extreme temperatures.
• Ensure adequate space for maintenance and servicing.
• The appliance must be installed on a solid, non-combustible wall capable of supporting its weight when full.

3.2. Gas and Water Connections

• Connect the natural gas supply line according to local codes. Use appropriate shut-off valves.
• Connect the cold water inlet and hot water outlet pipes. Ensure all connections are watertight.
• Install a pressure relief valve as required by local regulations.

3.3. Flue System

As a sealed (Estanco) appliance, it requires a specific concentric flue system for combustion air intake and exhaust gas expulsion. Follow the manufacturer's instructions and local building codes for flue installation.

3.4. Electrical Connection

Connect the appliance to a grounded electrical outlet as specified in the technical data. Ensure the power supply matches the appliance's requirements.

4. Operating Instructions

Once installed and checked by a qualified technician, the Fagor FE-11D PLUS/1 N is ready for operation.

4.1. Initial Start-up

1. Ensure all gas and water valves are open.
2. Plug in the appliance. The digital display should illuminate.
3. Open a hot water tap. The water heater will automatically ignite and begin heating water.
4. Allow water to run for a few minutes to purge any air from the system.

4.2. Temperature Adjustment

Use the right rotary knob on the control panel to adjust the desired hot water temperature. The digital display will show the set temperature. Rotate clockwise to increase temperature, counter-clockwise to decrease.

4.3. Water Flow Adjustment

The left rotary knob controls the water flow rate. Adjusting this knob can influence the temperature stability, especially at very low flow rates. For optimal performance, set it to a position that provides sufficient flow without causing temperature fluctuations.

4.4. Digital Display

The digital display provides real-time information, including the current water temperature, error codes (if any), and operational status indicators.

Regular maintenance ensures the longevity and efficient operation of your Fagor water heater. It is recommended that a qualified technician performs annual checks.

• External Cleaning: Clean the exterior casing with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Pressure Relief Valve: Periodically check the pressure relief valve for proper operation. Consult your technician for this procedure.
• Flue System Check: Ensure the flue system is clear of obstructions and properly sealed.
• Gas and Water Connections: Inspect for any signs of leaks or corrosion.
• Professional Servicing: Schedule annual maintenance with a certified technician to check internal components, clean the burner, and ensure optimal performance and safety.

6. Troubleshooting

This section provides solutions for common issues. For complex problems or if you are unsure, contact a qualified technician.

6.1. No Hot Water / Appliance Not Igniting

• Check Gas Supply: Ensure the main gas valve to the house and the appliance's gas valve are open.
• Check Water Supply: Ensure the cold water inlet valve is fully open.
• Power Supply: Verify the appliance is plugged in and there is power to the outlet. Check circuit breakers.
• Error Code: Check the digital display for any error codes and refer to the full service manual or contact support.

6.2. Insufficient Hot Water Temperature

• Water Flow: Reduce the hot water flow rate using the flow adjustment knob or by slightly closing the tap.
• Sediment Buildup: Over time, sediment can accumulate. Professional descaling may be required.

6.3. Unusual Noises

• Gurgling/Hissing: May indicate air in the system or mineral buildup.
