A wood burning stove with a horizontal flue system can be an excellent heating solution, especially when traditional vertical chimney installations are not feasible. In this article, we’ll explore the technical details and considerations of a wood burning stove with a horizontal flue, covering its components, installation requirements, and safety measures.
Components of a Horizontal Flue System
Stove: The heart of the system, the wood burning stove, is where the combustion of wood takes place, generating heat.
Flue Pipe: The flue pipe is the duct that connects the stove to the horizontal flue. It must be made of appropriate materials, typically stainless steel, and should have proper insulation to maintain high temperatures for an efficient draft.
Horizontal Flue: This is a horizontal section of the venting system that carries the exhaust gases from the stove to the exterior. It should have a slight upward slope to facilitate the proper draft.
Flue Elbows: To navigate around obstacles or to create the necessary rise, flue elbows are used. These should be installed according to the manufacturer’s guidelines.
Wall Pass-Through: When the horizontal flue passes through an external wall, a wall pass-through, often including a thimble, is installed to maintain a proper seal and prevent heat loss.
Installation Requirements
Proper Clearances: Ensure that the stove and flue components maintain the required clearances from combustible materials like walls, floors, and ceilings, as specified by the stove manufacturer and local building codes.
Slope and Rise: The horizontal flue should have a slight upward slope from the stove to the exterior to encourage the natural draft. This slope usually ranges from 1/4 inch to 1/2 inch per foot.
Sealing and Insulation: A horizontal flue system must be sealed and insulated properly to prevent heat loss and maintain the efficiency of the stove.
Thimble and Wall Pass-Through: When the flue passes through an external wall, the wall pass-through and thimble must be sealed correctly to prevent drafts and maintain safety.
Chimney Cap: Even with a horizontal flue, it’s important to have a chimney cap to protect the flue from rain and debris, preventing blockages.
Safety Measures
Carbon Monoxide Detector: Install a carbon monoxide detector in the room where the wood stove is located to ensure the early detection of any combustion issues.
Fireproof Wall Protection: Use fireproof materials or heat shields on walls near the stove and flue to prevent heat transfer and fire hazards.
Regular Maintenance: Perform routine inspections and cleaning to prevent creosote buildup, which can reduce the efficiency of the stove and pose a fire risk.
Conclusion
A wood burning stove with a horizontal flue can be a practical solution in various home setups. However, it’s crucial to follow technical details, adhere to clearances, and install the system correctly to ensure safety and efficiency. Always consult the manufacturer’s guidelines and local building codes, and if in doubt, seek professional assistance for the installation.
With the right setup and proper care, a wood burning stove with a horizontal flue can provide reliable heating while maintaining safety and compliance.
