Sealed Chamber Boiler BAXI COPPER 280 FI Manual – Complete PDF Guide

The BAXI COPPER 280 FI floor-standing boiler is a sealed model with an integrated boiler. This type of boiler, supported on the ground for the boiler’s weight, is an ideal solution for those who need a large capacity for domestic hot water production.

Characterized by a sealed combustion chamber, the boiler controls the combustion process internally, ensuring safety and isolation from the external environment. Although it has lower energy efficiency compared to condensing boilers, this model compensates with a balanced combustion system and an effective smoke extractor.

Boilers of this type do not fully exploit the sensible heat due to the need to prevent corrosion from condensation. Consequently, the water vapor produced by combustion, along with the associated latent heat, is expelled through the chimney, an effective solution to maintain the safety and efficiency of the system.

Maintenance Tips

Regular maintenance of the COPPER 280 FI boiler is crucial to preserve its efficiency and safety. It is strongly advised against for inexperienced users to attempt any technical intervention on the boiler. Any doubts or anomalies in operation must be immediately reported to an expert technician. Annual maintenance, carried out by qualified technicians, is fundamental for the correct operation of the appliance.

Warnings for the Use of Electric Energy

For safe use of the boiler, it is important to follow some basic rules:

• Do not touch the appliance with wet or damp body parts and avoid doing so barefoot.
• Avoid pulling electrical cords and ensure they are not damaged.
• Do not expose the appliance to adverse weather conditions such as rain or direct sunlight, unless otherwise indicated.
• In case of damage to the electric cord, immediately turn off the appliance and contact a qualified technician for replacement.

Additionally, ensure that the boiler is installed, put into operation, and maintained by authorized technicians to guarantee the validity of the warranty and safety in use. Improper use of the appliance and any unauthorized alterations could pose safety risks.

In Case of Gas Odor

• Do not operate electrical switches, the phone, or any other device that may generate electrical discharges or sparks.
• Immediately open doors and windows to create an air exchange that can quickly clear the room.
• Close the gas taps.
• Request the immediate intervention of professionally qualified personnel.

Guide to Components and Spare Parts

This section is dedicated to providing a complete overview of the various components and spare parts available for the COPPER 280 FI boiler. You will find detailed information on each part, from its main function to advice on when it might need to be replaced.

Automatic Air Purger

The automatic air purger is an essential component in the BAXI COPPER 280 FI boiler for effectively removing air from the heating system. Its role is crucial for maintaining the efficiency and safety of the heating system.

This economical device plays a vital role in avoiding circulation problems, particularly in aluminum radiators where the presence of air can cause malfunctions, especially after periods of inactivity.

It is recommended to periodically check the air purger and replace it if necessary, to ensure a problem-free start of the heating system at the beginning of the cold season. Its functionality is crucial for the proper operation of the entire domestic heating system.

Possible Improvement Works

The BAXI COPPER 280 FI boiler requires special attention to the proper cleaning of the flue pipe. Especially at the bends leading to the vertical section, dirt can accumulate, compromising the functionality of the smoke fan. It is essential to have a qualified technician ensure that the pipes are in optimal condition.

Integrating a Gas Tap with a Test Well

Not always does the meter provide a connection for instrumental tightness testing. A useful tip is to replace the gas tap under the boiler with a valve with a well equipped with an instrumental take-off, essential for the tightness test of the system. This element can be crucial in case of inspections and safety checks and certainly facilitates the maintenance of the COPPER 280 FI boiler.

In fact, during the maintenance of the appliance, it is mandatory to perform a suitable test like UNI 11137:2019 that verifies the correct tightness of the gas system.

Flushing the Heating System

Flushing the heating system is crucial to prevent clogging of the primary exchanger of the BAXI COPPER 280 FI boiler. Over time, especially in cast iron or aluminum systems, a metallic sludge can form that can clog the narrow passages of the exchanger.

After flushing the system, it is highly recommended to install a magnetic sludge filter on the BAXI COPPER 280 FI boiler. This filter plays an essential role in protecting the exchanger from the buildup of dirt and debris, ensuring greater efficiency and longevity of the heating system.

Additional improvements can include the installation of an advanced thermostat with relay function. This device allows for more effective management of heating hours, helping to optimize energy consumption.

Innovative Accessories

Enhance the functionality of your COPPER 280 FI boiler with these cutting-edge accessories:

• Advanced Programmable Thermostat: Control the temperature of your home with intelligent solutions that offer flexible programming and interactivity.
• Magnetic Filter Dirt Separator: An indispensable accessory for maintaining the efficiency and cleanliness of your boiler’s hydraulic circuit.

Magnetic Filter for Heating

Considered the best accessory to block the entry of dust and debris from the heating system into the device.

The magnetic filter, installed on the heating return line to the boiler, is essential for maintaining system efficiency. It retains harmful elements like dust and debris, preventing boiler blockage and reducing the risk of overheating the primary exchanger. Additionally, it helps to reduce pressure on the diverter valve, thus increasing its lifespan and reducing the chances of leaks.

Maintenance of the Polyphosphate Doser

If the tap water hardness exceeds 20 French degrees, a polyphosphate doser is recommended for the BAXI COPPER 280 FI boiler.

The polyphosphate doser, which can use powder or liquid additives, is vital for reducing limescale in the BAXI COPPER 280 FI boiler. These additives require constant replenishment to ensure maximum effectiveness.

Available in different variants, polyphosphates include:

• Powder Polyphosphates
• Liquid Polyphosphates

The choice of polyphosphate determines the type of mixing mechanism required.
