Garage Chimney Pipe Kits Through the Wall 

When to choose a through-the-wall wood stove pipe kit?

You should choose a through the wall wood stove pipe kit when a roof penetration isn’t possible or would create structural or layout challenges.

Garages, basements, cabins, sheds and workshops frequently rely on this configuration because the stove sits near an exterior wall. Other factors that make this option more practical are:

• Shorter interior runs;
• Easier routing around framing;
• Flexible exterior chimney height.

How does a through the wall chimney kit work?

When your stove is operating, hot exhaust gases rise naturally and create draft inside the chimney. In a through-the-wall setup, the stove connects to a short interior pipe that directs exhaust toward the exterior wall.

At the wall, the system transitions to a class A insulated chimney pipe. From there, the chimney runs vertically outside the building, where proper height supports stable draft and consistent airflow.

• The interior stove pipe handles the connection.
• The insulated chimney pipe handles the wall penetration and exterior run, keeping the surface temperatures controlled and draft reliable.

Installation overview and planning tips for through the wall wood stove pipe kits

MANUAL Installation Guide

Successful through-the-wall systems start by mapping the entire chimney path first, rather than assembling parts one at a time.

1. The layout begins at your stove’s collar;

2. Runs through a short interior stove pipe section;

3. Transitions at the wall and then continues vertically outside the building.

Keeping the interior run short and direct helps you keep draft before the wall pass-through. The chimney height is then built upward after the tee, based on draft needs, building height and exterior exposure. For step-by-step guidance, check our wood stove chimney pipe installation resources.

Quick tips for beginners

1. Start by planning the chimney height from the tee outlet upward, since exterior vertical rise plays a major role in draft and smoke evacuation. Many installers mention the 3-2-10 rule as a general guideline, but it should always be checked against local requirements and your specific layout.

2. Wall brackets aren’t decorative hardware. Spacing them roughly every 6 to 8 feet helps stabilize the chimney against wind and movement.

3. The base wall support carries the chimney’s vertical load, while brackets prevent lateral stress on the wall thimble and tee.

4. Use high-temperature sealant only where the instructions specify, not everywhere joints meet.

5. Respect the required clearances around interior stove pipe sections, especially if you’re using a single-wall pipe.

6. Before the final assembly, double-check your measurements, wall thickness and clearances, as small planning errors can affect draft, alignment and long-term reliability.

Why class A insulated chimney pipe is required for an installation through-the-wall

Passing a chimney through an exterior wall brings high flue temperatures close to framing, insulation and siding. That’s why building codes require insulated chimney systems at all wall penetrations.

A single-wall stove pipe is designed only for short interior connections. It must not pass through a wall because it:

• Has no insulation
• Transfers heat quickly
• Cannot keep safe clearances near combustible materials

Our class A chimney pipes are built specifically for wall and ceiling penetrations. Its insulation:

• Keeps exterior surface temperatures within safe limits
• Stabilizes flue gas temperature for consistent draft
• Helps reduce creosote buildup

A stove pipe and class A chimney pipe serve different roles. Using each in the right location supports safe, code-compliant and reliable stove performance.
