Installing a wood burning stove flue through a wall can be an efficient way to vent your stove, especially when a traditional chimney isn’t available. In this guide, we will provide accurate and concise information on how to safely and effectively route a wood stove flue through a wall, suitable for both technical and non-technical readers.
1. Assess Your Setup
Before you begin the installation, take the following factors into consideration:
Stove Location: Ensure that the stove is placed in a suitable location near an exterior wall, as this is where the flue will exit.
Clearances: Check local building codes and the stove manufacturer’s guidelines for required clearances from the wall. These clearances are crucial for safety.
Wall Composition: Assess the wall’s composition. Some materials, like brick or stone, may require additional considerations compared to standard drywall.
2. Choose the Flue Route
There are two common methods for routing a wood stove flue through a wall:
Direct Vent: This method involves installing a horizontal flue pipe directly through the wall to the exterior. It’s a simpler and more cost-effective approach but may limit where you place the stove in the room.
Chimney Chase: A chimney chase is a framed enclosure built around the flue pipe inside the house. It provides more flexibility for stove placement but is more complex to construct.
3. Install the Flue Pipe
For a Direct Vent:
Mark the Wall: Determine the ideal exit point for the flue. Measure and mark the locations on both sides of the wall.
Cut Openings: Cut a hole through the wall at the marked locations using a reciprocating saw or a hole saw.
Install Wall Thimble: Insert a wall thimble into the hole, which acts as a protective passage for the flue pipe.
Attach Flue Pipe: Connect the flue pipe to the stove’s flue collar and pass it through the wall thimble. Secure it in place.
Exterior Wall: On the outside, attach an exterior wall thimble and a rain cap to protect the flue opening from the elements.
For a Chimney Chase:
Build the Chase: Construct a framed enclosure inside the house that surrounds the flue pipe. Ensure proper clearances from combustible materials.
Flue Pipe Installation: Connect the flue pipe to the stove and pass it through the chase. Secure it in place.
Exterior Termination: At the exterior, install a termination cap on the chase to prevent water infiltration and protect the flue opening.
4. Ensure Proper Clearances
Maintain the specified clearances around the flue pipe to prevent heat transfer to combustible materials. These clearances are typically specified by your stove’s manufacturer and local building codes.
5. Insulation
For added safety and efficiency, it’s advisable to insulate around the flue pipe as it passes through the wall. Insulation will help minimize heat loss and prevent drafts.
6. Professional Inspection
After installation, it’s recommended to have your wood stove and flue system inspected by a professional to ensure compliance with safety standards and local regulations.
Conclusion
Properly routing a wood stove flue through a wall is an efficient way to vent your stove when a traditional chimney is not available. Remember that safety and adherence to local building codes are paramount. Always consult with a professional, follow the manufacturer’s guidelines, and consider local regulations to ensure a safe and efficient wood burning stove installation.
