2. Installation Guidelines and Fire Safety

Building Into Flammable Materials with Fire Wall

• Cavities in the structure must not be filled with insulation material.
• Use of fire walls such as 50 mm Jøtul Firewall, 110 mm brick, or equivalent materials with fireproof and insulating properties is mandatory.
• Minimum distances to flammable materials are specified in millimeters and must be strictly observed.
• Convection openings (upper and lower) are required in closed structures but can be omitted in open top structures, provided no top plate is installed.
• Cover plates protecting convection openings must be removed when installing into flammable materials protected by insulation.
• When installing insulated vertical flue pipes, the distance to the fire wall depends on the pipe extending fully to the insert.
• Floor plates and glass gaskets are recommended to tighten spaces and protect surrounding materials.

Minimum Distances and Clearances

• Distances to furniture from glass floor plates: minimum 800 mm.
• Minimum convection opening areas: 350 cm² (lower) and 500 cm² (upper).
• All distances indicated are minimum and must be adhered to for safety.

3. Material and Dimensions

• Materials referenced include ceramic stone and vermiculite for insulation and fire protection.
• Dimensions for various components are provided in millimeters, e.g., 75 mm, 40 mm, 15 mm clearances.
• Weight and area data are generally marked as N/A or not applicable.

4. Recommendations and Best Practices

• Do not fill cavities with insulation to avoid fire hazards.
• Ensure proper ventilation via convection openings unless the structure is open at the top.
• Use fire walls with proven fireproof and insulating abilities to separate flue pipes from flammable materials.
• Maintain minimum distances to prevent heat transfer and reduce fire risk.
• Remove protective cover plates when installing into flammable materials with insulation.
• Tighten gaps with glass gaskets to prevent heat leakage.

5. Summary of Critical Parameters

6. Limitations and Notes

• All distances are minimum and must not be reduced.
• Installation into flammable materials requires strict adherence to fire wall and clearance specifications.
• Open structures must not have top plates to allow proper convection.
• Weight and area data are not provided and should be verified separately if needed.

Conclusion

This document provides comprehensive technical specifications and safety guidelines for installing flue pipes and chimneys, emphasizing fire safety when integrating with flammable materials. Adherence to minimum distances, use of fire walls, and proper ventilation are critical to ensure safe operation.
