Installing a wood stove with a chimney that goes out a window can be a viable solution when a traditional chimney isn’t feasible. In this guide, we provide clear and concise technical details for both technical and non-technical audiences on how to correctly install a wood stove with a chimney that goes out a window.
Tools and Materials
Before you begin, gather the necessary tools and materials:
- Wood stove
- Stovepipe sections
- Wall thimble
- Chimney pipe sections
- Roof flashing
- Roof support bracket
- Insulation shield
- Anchor plate
- Chimney cap
- High-temperature silicone sealant
- Screws and anchors
- Measuring tape
- Screwdrivers, wrenches, and pliers
- Level
- Safety goggles and gloves
Step 1: Select the Location
Choose a location for your wood stove that allows for proper clearances. Place it near a window that is close to the desired installation point for the chimney.
Step 2: Assemble the Stove and Stovepipe
Assemble the wood stove per the manufacturer’s instructions. This includes attaching legs, handles, and dampers. Connect the stovepipe to the stove’s flue collar and extend it horizontally toward the window.
Step 3: Wall Thimble Installation
Measure and mark the location on the wall near the window for the wall thimble. Ensure it lines up with the horizontal stovepipe.
Cut a hole through the wall following the dimensions of the wall thimble, making it slightly larger than the chimney pipe.
Insert the wall thimble into the hole and secure it in place.
Step 4: Chimney Installation
Assemble the chimney pipe sections according to the manufacturer’s instructions, using high-temperature silicone sealant at the joints.
Connect the chimney pipe to the stovepipe using locking bands or clamps for a secure fit.
Extend the chimney pipe horizontally through the window, ensuring it maintains a continuous upward slope. The height should adhere to local building codes, typically extending 2 feet above any part of the roof within a 10-foot radius.
Step 5: Roof Support and Insulation Shield
Install a roof support bracket just outside the window to provide support for the chimney pipe.
Attach an insulation shield to the chimney pipe, just inside the window. This shield prevents contact with combustible materials.
Step 6: Roof Flashing and Anchor Plate
Slide the roof flashing over the chimney pipe, ensuring it is positioned flush with the window’s exterior.
Seal the flashing’s edges with high-temperature silicone sealant to prevent leaks.
Install an anchor plate just outside the window for stability.
Step 7: Chimney Cap
Install a chimney cap at the top of the chimney pipe to prevent rain, debris, and animals from entering.
Step 8: Final Checks
Ensure all connections are tight and secure. The chimney pipe should maintain a continuous upward slope without sags or dips.
Seal any gaps or joints with high-temperature silicone sealant to maintain an airtight and weatherproof seal.
Step 9: Safety and Maintenance
- Regularly inspect and clean your chimney to prevent creosote buildup, which can pose a fire hazard.
- Install a carbon monoxide detector in your home for added safety.
- Schedule an annual inspection by a professional chimney sweep to ensure proper function and compliance with local regulations.
In conclusion, installing a wood stove with a chimney that goes out a window can be a practical solution when a traditional chimney isn’t feasible. However, precision and adherence to safety standards are crucial. If you’re uncertain about any part of the process, it’s advisable to seek professional assistance to ensure safety and compliance with local building codes. A well-installed wood stove and window chimney will provide efficient and safe heating for your home.
