Vaillant Ecofit Pure 418 Boiler Details

The Vaillant Ecofit Pure 418 Boiler is a highly efficient, condensing heat generator designed for closed heating installations and hot water generation. It is engineered with safety as a top priority, requiring installation and servicing exclusively by qualified, competent professionals to prevent risks such as gas leaks, electric shock, or material damage.

This boiler adheres to the Benchmark Scheme, ensuring that it is installed and maintained according to industry best practices and Building Regulations. A key feature is its room-sealed design, meaning it does not require compartment ventilation. This provides flexibility in installation location as combustion air is not drawn from the immediate room.

Accessibility for maintenance is facilitated by the product's design, including easily removable front casings and side sections. However, it is crucial to remove only one side section at a time to prevent mechanical distortion. The unit is designed for a fixed installation and is not suitable for use in vehicles.

Operation is intuitive, guided by an interface detailed in the accompanying operating instructions. For installers, a dedicated "installer level" provides access to diagnostic codes (D), status codes (S), fault codes (F), and various check programmes (P) for comprehensive system management and troubleshooting.

The system also incorporates a burner anti-cycling time in heating mode to prevent frequent on/off switching, thereby enhancing energy efficiency and component longevity. This smart feature helps manage heat demand fluctuations effectively.

Critical aspects of installation include proper heating water quality management. The manual emphasizes checking and treating heating water to prevent corrosion, particularly for aluminium components. It advises against unsuitable additives and lists approved solutions for cleaning and frost protection.

The boiler's condensate trap needs to be filled with water during start-up to prevent flue gas escape. Regular checks for gas flow rate, gas connection pressure, and CO₂ content are mandatory to ensure safe and optimal combustion.

Troubleshooting is supported by a robust fault code system (F.xx) which stores the last 10 fault messages. This allows quick identification and resolution of issues. If faults persist, Vaillant customer service is readily available.

Routine inspection and maintenance are vital for the Ecofit Pure 418, with annual checks recommended. These include inspecting flue integrity, connections, condensate drainage, and the overall condition of components. Specific tasks like cleaning the heat exchanger and condensate trap are also detailed.

Before handing over to the end user, installers must explain safety devices, product operation, and the importance of adhering to maintenance intervals. The manual also provides guidance on environmentally responsible recycling and disposal of the packaging.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Vaillant Ecofit Pure 418 Boiler, and we answer them below.

Who is qualified to install and service the Vaillant Ecofit Pure 418 Boiler?

Only competent persons who are sufficiently qualified should carry out installation, dismantling, start-up, inspection, maintenance, repair, and decommissioning of the boiler.

Does the Ecofit Pure 418 require compartment ventilation?

No, the Vaillant Ecofit Pure 418 is a high-efficiency, room-sealed appliance and does not require compartment ventilation. It can only be fitted with a concentric flue system.

What should I do if I smell gas in the building?

Immediately avoid rooms that smell of gas, open doors and windows for ventilation, extinguish any naked flames, do not use electrical switches or phones, close the emergency control valve, and warn other occupants. Then, leave the building and notify the gas supply company or National Grid from outside.

How often should the Vaillant Ecofit Pure 418 be inspected and maintained?

The manufacturer recommends adhering to minimum inspection and maintenance intervals, with an annual inspection. For products not under an annual service agreement, maintenance must be carried out at least once every five years.

What type of water is suitable for the heating system?

The heating water quality is crucial to prevent material damage. It should be checked for sediment and magnetite. The pH value at 25°C should be between 6.5 and 8.5. If the system volume or hardness exceeds specified limits, the water must be treated. Only approved additives for cleaning and frost protection should be used.

How do I access the installer level for diagnostics?

To access the installer level, press the and "i" buttons simultaneously. Then, press to access the installer level, set the code value to "17," and confirm. You can then navigate to check programmes (P), fault codes (F), and diagnostics codes (D).

What is the purpose of the burner anti-cycling time?

The burner anti-cycling time is an electronic restart lockout activated for a specific period each time the burner switches off in heating mode. This prevents frequent on and off switching of the burner, which helps conserve energy and extend the life of the components.

What does a fault code like F.22 or F.28 indicate?

Fault codes (e.g., F.xx) indicate specific issues. F.22 typically signifies a safety switch-off due to low water pressure, meaning no or insufficient water in the product. F.28 indicates a failure during start-up, such as ignition unsuccessful, which could be due to gas supply issues, air in the gas, or ignition system defects. A full list of fault codes is in the manual's appendix.

Can I replace components with non-original spare parts?

The manufacturer strongly recommends using only original spare parts. Using non-certified or unauthorized parts may void the product's conformity and compliance with applicable standards, potentially compromising safety and operation.

How is the condensate discharged from the boiler?

The condensate discharge pipe should have a continuous fall and terminate at a suitable, frost-free drain point. It must use PVC or other suitable material for non-neutralised condensate. If material suitability cannot be guaranteed, a neutralising system should be installed.

What is Benchmark and why is it important for my boiler?

Benchmark is a scheme ensuring boilers are installed, commissioned, and serviced by competent persons according to manufacturer's instructions and Building Regulations. Vaillant is a licensed member, and the Benchmark Checklist should be completed and kept by the customer as proof of compliance and for future reference.

What are the minimum clearances required around the boiler for installation?

Minimum clearances vary, but typically include 150 mm at the top (or 75 mm for rear air/flue connection, reducible to 20mm if removable surface above), 150 mm at the bottom, 5 mm on the sides (70 mm if side sections need removing), and 600 mm in front for servicing access.
