Key Takeaways:
-
The Setup: A "Through-the-Wall" install connects an interior stove to an exterior chimney stack by passing through a combustible wall.
-
Critical Safety: You must use a "Wall Thimble" and insulated "Class A" pipe when passing through the wall to prevent fire hazards.
-
Interior vs. Exterior: Use black stove pipe inside the room and transition to stainless steel Class A pipe for the exterior run.
-
The Solution: A pre-bundled wood stove chimney kit ensures you have all the necessary brackets, tees, and caps for a code-compliant install.
Installing a wood stove is one of the best ways to add warmth and value to your home. However, figuring out exactly which parts you need can be frustrating. You have the stove, but how do you get the smoke safely from the living room to the outdoors?
One of the most common installation methods is the "Through-the-Wall" setup. This configuration involves running the pipe up from the stove, turning 90 degrees to pass through an exterior wall, and then running vertically up the side of the house.
To help you plan your project, we have broken down the essential components you will need.
The Interior Connection
Inside the house, you will typically use single-wall or double-wall black stove pipe. This is the pipe you see. It connects directly to the collar of your wood stove.
Stove Pipe: This rises vertically from your stove.
Elbow: A 90-degree elbow turns the pipe horizontal to aim it at the wall.
Passing Through the Wall
This is the most critical safety point. You never pass standard black stove pipe through a wall. Instead, you must transition to insulated Class A chimney pipe using a specialized kit.
Chimney Adapter: This connects your black interior pipe to the insulated exterior pipe.
Wall Thimble: This is a safety sleeve that goes into the wall framing. It ensures the hot pipe maintains the required clearance distance from your drywall and studs to prevent a fire hazard.
The Exterior Stack
Once the pipe is outside, it needs to turn vertical again and rise above your roofline.
Tee with Cap: This piece connects the horizontal pipe coming through the wall to the vertical pipe going up. It usually includes a removable cap on the bottom for easy cleaning.
Wall Straps: These brackets secure the heavy pipe to the side of your house every few feet.
Class A Chimney Pipe: These are the insulated lengths of pipe that form the chimney stack itself.
Chimney Cap: As we discussed in our previous guide, this tops off the system to keep rain and animals out.
The Simple Solution: A Complete Kit
If tracking down these individual part numbers sounds complicated, you are not alone. That is why we created our 6 inch through the wall chimney kit.
Instead of guessing, you can get a pre-bundled package that includes the wall thimble, tee, cap, straps, and supports in one click. You simply add the lengths of pipe needed for your specific height. It is the fastest and safest way to ensure you have every component required for a code-compliant install.
