Frequently Asked Questions - Assento CPG 6TF AUTO DISP BLA Haceb
What type of gas does the Haceb Assento CPG 6TF AUTO DISP BLA water heater use?
This model is compatible with both natural gas (NG) and liquefied petroleum gas (LPG). Before installation, check the gas type label on the unit or the manual to confirm and adjust the gas nozzle accordingly.
How do I set the desired water temperature?
Use the digital control panel to adjust the temperature from 35°C to 65°C. Press the up/down arrows to select the desired temperature; the current setting is shown on the LCD display.
What does the error code E1 or E2 mean?
Error codes are part of the self-diagnostic system. E1 typically indicates a flame failure or ignition issue, while E2 may reference an overheating condition. Check the user manual for a complete list and troubleshooting steps, but common fixes include checking gas supply, ignition batteries, or venting blockages.
Can I use this water heater during a power outage?
The ignition system requires electrical power. If your model uses batteries (2 × 1.5V D cells), it can operate without mains power, provided the batteries are fresh. Models with AC-only ignition will not work during a power outage.
How often should I perform maintenance?
It is recommended to have a qualified technician inspect and clean the water heater at least once a year. For areas with hard water, descaling the heat exchanger every 6 months can prevent scale buildup and maintain efficiency.
What is the minimum water pressure required?
This tankless water heater needs a minimum water flow of about 3 liters per minute to activate. Ensure the incoming water pressure is between 0.02 MPa and 0.8 MPa (0.2–8 bar) for optimal operation.
Can the unit be installed outdoors?
The Assento CPG 6TF AUTO DISP BLA is designed for indoor installation only unless specifically labeled as an outdoor model. It requires proper venting to the outside, so it should be installed in a well-ventilated room or connected to an appropriate flue system.
How do I clean the external surfaces?
Use a soft, damp cloth with mild soap to wipe the exterior. Do not use abrasive powder, steel wool, or chemical solvents, as they may damage the finish. Make sure the unit is cool and disconnected from the power before cleaning.
What should I do if the water heater produces no hot water?
First, check that the gas supply valve is open and the gas supply is sufficient. Then verify the batteries or AC power to the ignition system. If the display shows an error code, refer to the troubleshooting section. If nothing works, contact a certified Haceb technician.
Are spare parts available for this model?
Yes, Haceb provides spare parts such as thermocouples, gas valves, water flow valves, and electronic boards through authorized service centers. The modular design makes replacement simple, and the repair is cost-effective compared to replacing the whole unit.
