Wood Burning Stove Through-Wall Kit: A Practical Guide

A wood burning stove through-wall kit is a key component when it comes to safely and efficiently venting your stove. In this article, we will provide precise technical details and instructions for installing and using a through-wall kit with your wood burning stove.

The Components

A typical wood burning stove through-wall kit consists of several essential components, each serving a specific purpose:

1. Stove Pipe

The stove pipe connects your wood stove to the through-wall kit. It’s often made of stainless steel or black stove pipe. The pipe should be of the appropriate diameter to match your stove’s outlet.

2. Wall Thimble

The wall thimble is a crucial part of the kit. It provides a passage through the wall for the stove pipe. Ensure that it is made of durable and fire-resistant materials.

3. Insulated Pipe

Insulated pipe, also known as a chimney pipe or class A pipe, is used to extend through the wall and beyond your home. It is insulated to prevent excessive heat transfer to combustible materials. This pipe is often double-walled with insulating materials in between.

4. Exterior Wall Termination

The exterior wall termination is the endpoint of the through-wall kit on the outside of your home. It usually includes a rain cap to keep water out. Some terminations also include a spark arrestor to prevent sparks from escaping.

Installation

Proper installation of the wood burning stove through-wall kit is essential for safety and efficiency. Follow these steps:

1. Planning and Positioning

Choose an appropriate location on the wall for the stove pipe. Ensure it complies with local building codes and manufacturer’s guidelines, including minimum clearances to combustible materials.

2. Cutting the Hole

Carefully cut a hole through the wall using the dimensions provided in the manufacturer’s instructions. Install the wall thimble into the hole, securing it to both sides of the wall.

3. Connecting the Stove Pipe

Connect the stove pipe to the stove’s flue collar. Make sure the connection is secure, and the pipe runs horizontally into the wall thimble.

4. Installing the Insulated Pipe

Extend the insulated pipe through the wall thimble and outside the house. Follow the manufacturer’s instructions for joining and sealing the sections. Ensure the pipe is properly supported and braced.

5. Exterior Termination

Attach the exterior wall termination to the insulated pipe on the outside of your home. This should be securely fastened to prevent wind or weather-related issues.

6. Final Inspection

Before using your wood stove, have your installation inspected by a professional to ensure it complies with safety standards and local regulations.

Using the Through-Wall Kit

Once the through-wall kit is installed, using it is relatively straightforward:

  • Start your fire as usual in the wood stove.

  • Ensure the stove’s draft controls are set correctly for efficient combustion.

  • The through-wall kit will safely vent the smoke and gases outside, providing a clean and safe heating experience.

Maintenance

Regular maintenance is crucial for the through-wall kit’s longevity and performance:

  • Inspect the entire system for any signs of wear or damage.

  • Keep the exterior termination clean and free from obstructions.

  • Have your chimney or venting system professionally cleaned and inspected annually to remove creosote buildup and ensure safety.

A wood burning stove through-wall kit is a valuable addition to your heating setup, providing efficient and safe venting. By following the manufacturer’s instructions during installation and conducting routine maintenance, you can enjoy the warmth and comfort of your wood stove with peace of mind. Always adhere to local building codes and regulations when installing your through-wall kit.
