Frequently Asked Questions - ASA 4000-IN Baxi
What is the recommended water pressure for the Baxi ASA 4000-IN?
The recommended water pressure is between 1.5 and 2.5 bar. Ensure the pressure is stable to maintain optimal performance. If the pressure drops below 1 bar, the low water pressure cut-off will activate.
How often should I service my water heater?
It is recommended to have your water heater serviced annually by a qualified technician. Regular servicing ensures safe operation, maintains efficiency, and extends the lifespan of the unit.
What should I do if the pilot light keeps going out?
If the pilot light repeatedly goes out, first check the thermocouple for damage and clean the burner. If the issue persists, inspect the gas supply and pressure. Contact a professional if unsure.
Can this unit be used with propane instead of natural gas?
The Baxi ASA 4000-IN is factory-set for natural gas. Conversion to propane requires a conversion kit and must be performed by a licensed technician. Do not attempt to modify the gas valve yourself.
How do I adjust the water temperature?
Use the temperature adjustment knob on the front panel. Turn it clockwise to increase temperature and counterclockwise to decrease. Wait a few minutes for the water to reach the new setting. The maximum temperature is typically 60°C.
What does the flashing LED on the display mean?
A flashing LED indicates a fault condition. Refer to the error code table in the user manual. Common causes include ignition failure, overheating, or low water pressure. Reset the unit by turning it off and on after correcting the issue.
Is this water heater suitable for a small apartment?
Yes, the ASA 4000-IN has a 40-liter capacity which is ideal for 1-2 persons. It provides a continuous supply of hot water for showers and kitchen use. It is compact and wall-mounted to save space.
What maintenance is required for the burner?
The burner should be cleaned annually to remove dust and debris. Use a soft brush and vacuum. Check for corrosion and ensure all jets are clear. This helps maintain proper combustion and efficiency.
Does the unit require a dedicated electrical circuit?
Yes, the water heater requires a dedicated 220-240V electrical circuit with a proper earth connection. It draws power for the electronic ignition, fan, and controls, typically around 50-100 watts. Do not use extension cords.
How can I improve the energy efficiency of my water heater?
To improve efficiency, set the temperature to 55-60°C, insulate hot water pipes, and service the unit regularly. Additionally, use low-flow showerheads to reduce water consumption. The condensing technology already recovers heat from exhaust gases.
