The Contura i5 is a versatile stove insert designed for installation in open fireplace openings. Known for its modern design, efficient combustion technology, and eco-friendly credentials, the i5 is a popular choice among homeowners looking to improve heating efficiency while maintaining aesthetic appeal. This guide draws from verified technical documentation and installation instructions to provide a detailed overview of the Contura i5, covering its key features, installation considerations, and maintenance requirements.
Overview of the Contura i5
The Contura i5 is designed to fit into most open fireplace openings, making it a suitable upgrade for existing fireplaces. It is available in two primary configurations: double doors and panorama door. The double-door version includes an integrated handle and easily accessible damper control, while the panorama door model emphasizes a large, clean glass surface for an unobstructed view of the flames.
The i5 model is certified under EN 13229 standards, ensuring compliance with European safety and performance regulations. It is also recognized with the Swedish Swan label, a certification for environmentally sustainable products, indicating its reduced environmental impact.
Installation of the i5 can be performed without affecting the existing chimney system, as it is designed to be removed for maintenance or replacement while the chimney remains intact. This feature simplifies future modifications and reduces potential disruption during installation.
Installation Requirements and Preparations
Before beginning the installation of the Contura i5, it is essential to ensure that the fireplace and chimney meet the necessary specifications for safe and efficient operation. The following factors must be considered:
Chimney Requirements: The chimney must meet specific height and length criteria to ensure proper draft. According to the technical documentation, the chimney should rise at least 1 meter above the roof ridge and have a total length of at least 3.5 meters. The cross-sectional area of the chimney is also important; for existing brick chimneys, the area should be between 150 and 200 cm². These dimensions help prevent poor draught, which can lead to inefficient combustion and potential smoke accumulation in the room.
Clearance and Ventilation: The area in front of the Contura i5 must be protected against falling embers. A non-flammable hearth of sufficient thickness is required, and the floor in front of the hearth must be accessible for cleaning and maintenance. Additionally, the soot hatch must remain easily accessible for routine inspections and cleaning.
Outdoor Air Connection: The i5 model supports the option to connect to an external air supply, which can improve combustion efficiency by providing fresh air directly to the firebox. This is particularly beneficial in homes with tightly sealed environments where indoor air may be insufficient for optimal burning.
Unpacking and Initial Setup: Before installation, the transport lock inside the insert must be removed. This is done by unscrewing the securing screws that hold the counterweight in place during shipping. Care should be taken to ensure that all loose parts are removed and that the hatch mechanism is properly lubricated with high-temperature-resistant grease, as specified in the installation manual.
Step-by-Step Installation Process
Preparation of the Fireplace Opening: Measure the dimensions of the fireplace opening to confirm compatibility with the Contura i5. Ensure that the area is clean and free of debris or obstructions that might interfere with installation.
Insert Placement: Carefully position the Contura i5 within the fireplace opening. Ensure that the unit is level and that all structural supports are in place to prevent shifting or vibration during operation.
Chimney Connection: Connect the flue outlet of the insert to the existing chimney system. The Contura i5 is designed for a backward flue outlet, and proper alignment is critical for unimpeded smoke flow.
Ventilation Setup (Optional): If an external air supply is to be connected, install the necessary ducting and ensure that the airflow is unobstructed. This step enhances combustion efficiency and can reduce the risk of smoke spillage.
Hearth and Floor Protection: Install a non-flammable hearth of at least the required thickness in front of the insert. Ensure that the floor in front of the hearth is also protected and that the soot hatch remains accessible for regular maintenance.
Final Inspection and Testing: Once installed, conduct a visual inspection to confirm that all components are correctly positioned and that there are no leaks or misalignments. A test fire may be lit to observe combustion performance and ensure that the chimney draft is functioning correctly.
Maintenance and Troubleshooting
Proper maintenance is essential for the long-term performance and safety of the Contura i5. Regular cleaning of the glass and soot hatch is recommended to maintain visibility and airflow. The technical documentation suggests using a specialized cleaning solution for the glass to avoid scratches or damage. Additionally, the hatch runners should be periodically inspected and re-lubricated with high-temperature grease, as specified in the installation manual.
If issues arise during operation, the following troubleshooting steps may be helpful:
Poor Draft or Smoke Spillage: Check the chimney height and cross-sectional area as previously described. Ensure that there are no obstructions or nearby structures that might interfere with airflow.
Difficulty Lighting the Fire: Confirm that the air supply is adequate and that the damper is fully open. If the problem persists, a blockage in the chimney or flue system may be the cause.
Glass Cloudiness or Soot Build-Up: This is typically a sign that the fire is not burning at an optimal temperature. Adjust the airflow settings and ensure that the firewood is dry and of high quality.
Damper or Handle Malfunction: Inspect the damper control for debris or misalignment. If the damper is difficult to operate, it may need to be cleaned or adjusted. In some cases, a Contura dealer may be required for repairs or replacements.
Performance and Efficiency Considerations
The Contura i5 is designed to deliver rapid heating through its efficient convection technology, which circulates warm air throughout the room. The large glass surface allows for an unobstructed view of the fire, enhancing the aesthetic appeal while maintaining functionality.
The use of advanced combustion technology ensures that the logs burn more efficiently, minimizing soot and extending burn times. This not only improves heating performance but also reduces the frequency of cleaning and maintenance tasks.
The insert’s design is optimized for a wide range of environments, including open and corner fireplaces. The double-door configuration, with its integrated handle and accessible damper control, offers a user-friendly interface for managing the fire. The panorama door model, on the other hand, emphasizes visual appeal with its expansive glass panel.
Environmental and Safety Certifications
The Contura i5 is manufactured in compliance with Sweden’s strict environmental standards, ensuring that it is produced using sustainable practices. The product is recyclable without the release of toxic substances, and the combustion process meets high efficiency standards to reduce emissions.
As the only Swedish Swan-labelled cassette in its category, the Contura i5 is recognized for its minimal environmental impact. This certification reflects the manufacturer’s commitment to sustainability and provides users with a product that aligns with eco-friendly values.
Safety is also a key consideration, with the insert designed to operate within a controlled and secure environment. The use of non-flammable materials and proper installation practices further enhance safety for users.
Conclusion
The Contura i5 represents a well-designed and efficient solution for homeowners seeking to enhance the heating capabilities of their existing fireplaces. With its modern design, advanced combustion technology, and environmental certifications, it offers a balance of functionality, aesthetics, and sustainability.
Installation requires careful attention to the specifications outlined in the technical documentation, particularly regarding chimney dimensions and airflow. By following the recommended procedures, users can ensure that the insert operates safely and efficiently for years to come.
Regular maintenance and troubleshooting practices are essential for preserving the performance and longevity of the Contura i5. From cleaning the glass to inspecting the damper and chimney, these tasks help maintain optimal operation and prevent potential issues.
