Installing a wood stove in a space with a cathedral ceiling can be a challenging but rewarding project. To ensure safety and efficiency, it’s crucial to install the wood stove chimney correctly. In this guide, we’ll provide precise instructions for installing a wood stove chimney through a cathedral ceiling.
Materials and Tools:
Before you begin, gather the necessary materials and tools:
Materials:
- Stove Pipe: Double-wall insulated stove pipe suitable for your wood stove.
- Chimney Pipe: Double-wall insulated chimney pipe.
- Roof Flashing: A roof flashing kit designed for cathedral ceilings.
- Storm Collar: To create a weatherproof seal around the chimney pipe.
- Roof Support Kit: Designed for cathedral ceiling installations.
- Firestop Spacer: To maintain proper clearances through the ceiling.
- High-Temperature Silicone Sealant: To seal pipe connections.
- Anchor Plate: For securing the chimney pipe to the ceiling.
Tools:
- Tape Measure: For precise measurements.
- Screwdriver and Screws: For securing components.
- Level: To ensure the chimney is straight.
- Chalk Line: For marking guidelines.
- Hole Saw: To cut holes for pipe passage.
- Wrenches: For tightening connections.
- Safety Gear: Including gloves and safety glasses.
Installation Steps:
Check Local Regulations: Before beginning, check local building codes and regulations. Permits may be required for wood stove installations.
Determine the Location: Decide on the optimal location for your wood stove. Ensure it complies with clearance requirements from combustible materials.
Install the Stove: Place and secure the wood stove in your chosen location, following the manufacturer’s guidelines for clearances.
Determine Ceiling Penetration Point: Measure and mark the point on the ceiling where the chimney will penetrate.
Cut the Hole: Use a hole saw to create an appropriately sized hole in the ceiling. This hole should match the diameter of the chimney pipe you’re using.
Install Roof Support: Secure the roof support kit to the ceiling, aligning it with the hole. Use a level to ensure it’s plumb.
Attach the Firestop Spacer: Slide the firestop spacer over the chimney pipe and lower it onto the roof support kit. Ensure it’s centered over the hole.
Install Roof Flashing: Place the roof flashing over the chimney pipe, ensuring it fits securely over the hole in the roof. Attach it with screws, creating a watertight seal.
Attach the Storm Collar: Slide the storm collar over the chimney pipe and secure it to the roof flashing, creating a weatherproof barrier.
Connect the Chimney Pipe: Assemble the chimney pipe sections and secure them using the provided locking bands or screws. Make sure they fit snugly.
Secure the Anchor Plate: Attach the anchor plate to the chimney pipe, using screws to secure it to the ceiling joists.
Seal Joints: Use high-temperature silicone sealant to seal all the joints and connections in the chimney system.
Extend Above the Roof: Continue adding chimney sections to extend the pipe above the roofline. Follow manufacturer’s recommendations for height and clearances.
Complete the Exterior: Install a rain cap or termination cap to prevent weather and animals from entering the chimney.
Inspect and Test: Before using the wood stove, inspect the entire chimney system for any issues. Start a small fire and ensure the system draws correctly and there are no leaks or obstructions.
By following these steps, you can safely and effectively install a wood stove chimney through a cathedral ceiling. It’s essential to adhere to local regulations and the manufacturer’s instructions for both your wood stove and chimney components to ensure a safe and efficient heating system in your home.
