Wood burning stoves are renowned for their efficient heating capabilities and versatility. For those interested in a wood stove that vents out the back, this technical overview will provide essential information on how these stoves work and what to consider when using them.
The Venting Process
A wood burning stove that vents out the back, often called a rear-vent stove, has a different venting system than traditional stoves. The key components include:
Stove Pipe: This pipe connects the stove to the chimney or vent. In a rear-vent stove, the stove pipe exits from the rear of the stove, directing smoke and combustion gases horizontally to the wall and then vertically to the chimney.
Chimney or Vent Pipe: The stove pipe connects to a chimney or vent pipe, which directs the gases outside.
Wall Pass-Through: When venting out the back, a wall pass-through is used to safely transition the stove pipe through the wall and into the chimney or vent pipe.
Chimney or Vent Termination: The chimney or vent pipe extends outside the house, where it terminates with a cap or terminal designed to prevent downdrafts and protect against weather.
Installation Considerations
Proper installation of a wood burning stove that vents out the back is essential for safety and efficiency. Here are key technical details to consider:
Clearances: Maintain specific clearances from combustible materials like walls, floors, and furniture. The exact clearance requirements vary depending on your stove model and local building codes.
Wall Thickness: Ensure the wall is of appropriate thickness and material to accommodate the wall pass-through assembly.
Fireproofing: Install non-combustible material like fireproof board or insulated stove pipe wall thimbles to protect the wall.
Chimney Height: The chimney or vent termination should extend above the roofline to prevent downdrafts and ensure proper draft.
Professional Installation: Due to the technical intricacies and safety concerns, professional installation by a certified technician is highly recommended.
Advantages of Rear Venting
Venting out the back offers some advantages, including:
Space Efficiency: Rear venting can save space in the room, as it doesn’t require the stove to be positioned far from the wall.
Aesthetics: The stove can be positioned closer to the wall, allowing for a neater appearance and a more centralized location in the room.
Maintenance
Proper maintenance is crucial for safety and stove longevity. Regularly check for the following:
Creosote Buildup: Inspect the chimney or vent for creosote buildup, which can lead to chimney fires. Cleaning may be required to remove creosote.
Airflow: Ensure that the stove pipe and chimney are clear of obstructions that might hinder airflow and draft.
Seals and Gaskets: Check seals and gaskets for signs of wear or damage, as they maintain an airtight seal, crucial for efficient operation.
In conclusion, a wood burning stove that vents out the back is a practical and efficient heating solution. Proper installation and maintenance are vital to ensure safe and effective operation. Understanding the technical aspects of the venting system is essential for making the most of your wood stove while enjoying a warm and cozy environment.
