What is Wall Stove Pipe?
A stove pipe is used to vent a wood-burning stove. It can be used only inside the room where the stove is attached. It is placed between the bottom of the ceiling and the top of the wood stove.
The main purpose of a stovepipe is to ventilate the excessive temperature made by the wood burning outside the house.
Types of Wall Stove Pipe
You will find 3 types of stove pipe available:
- Single-wall stove pipe
- Double-wall stove pipe
- Triple wall stove pipe
Single Wall Stove Pipe
It’s the most used stove pipe. It has a vertical clearance of 12’’. Again, when used horizontally, it requires an 18” clearance to the ceiling. It also emits some heat from the pipe into the room.
Double Wall Stove Pipe
It is a double-layered stove pipe. It requires only 8” of clearance to the ceiling and 6” clearance to the wall. It is more durable at higher temperatures and also has an internal air-cooling system.
Triple Wall Stove Pipe
It is generally used to protect the room from high temperatures, created by a stove. It requires only 1.5” clearance to the combustibles. It is more durable than single-wall and double-wall stove pipes.
Through the Wall Stove Pipe-How to Connect
Stovepipes are not recommended to use through the wall. Yet if it’s a must, then you can use a double stove pipe with help of a through-the-wall kit.
- Select a location
- Take the measurement and mark the outer line
- Cut and remove the wall
- Place the thimble known as the “Through the wall stove kit”.
- Connect the stovepipes to the 45 degrees or 90 degrees elbow
- Connect the stovepipes to the thimble
- At last transition a high-temperature chimney pipe to the double wall stove pipe

When to Use Wall Stove Pipe
To select what type of stove pipe you should use, you need to know the difference between them.
Single Wall vs Double Wall Stove Pipe
The purpose of a wall stove pipe is to emit excessively hotter air out of the room through the chimney.
Single Wall Stove Pipe
A single-wall stove pipe is cheaper to buy. It needs a clearance of 18”. It emits heat in the room from the pipe and also can be cut according to your requirement. And the single wall stove pipe’s temperature rises maximum where it is connected to the stove.
As a single wall stove pipe doesn’t have an air-cooling structure inside it so it becomes too hot and maintains the temperature throughout the pipe. It also radiates some temperature to the room.
Double Wall Stove Pipe
A double-wall stove pipe might be more costly but it has superior quality. In a double-wall stove pipe, the pipe consists of two walls and an air cooling system internally.
So it keeps the pipe’s outside cool and safe by keeping the temperature inside it. Yet, it becomes quite untouchable hot in the lower parts near the stove.
But while going through the upper side, it gradually becomes cooler. The double-wall stove pipe can also withstand higher temperatures compared to a single-wall.
It provides more floor space as it needs only 6” clearance. So it is obvious that a double wall stove pipe is better and safer to use.
Benefits of Transitioning from Single Wall to Double Wall Stove Pipe
It is rare for a single-wall stove pipe to be better than a double-wall stove pipe. Let’s look at some benefits you get by transitioning to a double wall from a single wall stove pipe –
- The double-wall stove pipe needs less space.
- The outside gets less hot.
- It keeps the heat inside the pipe.
- It has an internal air-cooling system.
- It is more durable in high temperatures.
Single to Double Wall Stove Pipe Adapter
As you know, an adapter is needed for single and double-wall pipes. So let’s learn about it.
A single to double-wall stove pipe adapter is used to ensure that the connection between the pipes has enough support to hold each other. It reduces the risk of disconnection between the pipes and other leakages.
Types of Single to Double Wall Stove Pipe Adapters
There are two types of adapters available.
- Single wall pipe to the male end of the adapter & female end to double wall pipe
- Single wall pipe to the female end of the adapter & male end to double wall pipe
How to Connect Single Wall Stove Pipe to Double Wall in 3 Steps
Already you know all about wall stovepipes, the benefits of the transition from a single wall to a double wall stove pipe, and the adapter. So, it’s time to learn how to connect them.
For this purpose, you need to follow the single to double-wall stove pipe construction. Remember to use an adapter to connect the pipes while following the procedures stated below-
Step 1: Connect the Single Wall Pipe to the Stove
You need to connect the single wall pipe to the stove. For that, you have to go through the following steps-
Step 1: Measure the diameter of the circular flange extending from the stove. It may exit vertically from the top, or horizontally from one side or the back. Most stovepipes are 6 inches wide, but make sure to check.
Step 2: A stovepipe will have slightly different ends. One end is indented on one side, while the large end fits on the flange. For more confirmation, the smaller end will be crimped or crinkled on one side. After confirming, fit the large end to the flange.
Step 3: Set the single-walled pipe on top of the flange. Push the pipe through the flange while twisting it gently. Once it has slipped over the flange, start rotating it.
Step 4: Push the pipe down on top of the stove until the flange disappears inside the pipe. It will ensure that the flange is located correctly.
Step 2: Connect the Adapter
Now it’s time to connect the adapter. There are various brands of single-wall to double-wall adapters. All of them have two ends.
- Male End
- Female End
Once the adapters are picked, you must connect them to the stovepipes. There are two ways to do this.
Way 1: Connect the female end to the double-wall pipe and the male end to the single-wall pipe. Insert the adapter between the pipes. Slip the female end of the adapter into the double-wall stove pipe and attach the male end to the single-wall pipe.
Way 2: Connect the male end to the double-wall pipe and the female end to the single-wall pipe. Place the adapter between the double-wall stovepipe and the single-wall pipe. Attach the male end to the double-wall stovepipe and the female end to the single-wall pipe.
Step 3: Tighten up The Clamp
You need to tighten the clamp connected to the adapter. This will help to hold the lips of the pipes together. So there is less chance of leaks. There you have it. Your stove pipe installation from single wall to double wall is done.
Thermometer for Double Wall Stove Pipe
A stove pipe thermometer is used to measure the temperature of the air going through the pipe. In the case of a double-wall stove pipe, you need to use a stove pipe probe thermometer.
It is used by inserting into a drilled hole in the pipe right in the way of the blowing air. By monitoring the temperature readings provided by the probe thermometer, you can adjust the stove temperature accordingly. There are certain temperature levels to maintain. Which are-
- 100°F to 400°F for Low Temperature
- 400°F to 900°F for Safe Temperature
- 900°F to 1200°F for High Temperature
Does an electric fireplace need a stove pipe kit?
No, you don’t need to install any stove pipe kit with your electric fireplace. Because an electric fireplace doesn’t have any fumes or gas.
Should I use a single or double-wall stove pipe?
Although it depends on your requirements to determine whether to go for a single-wall or double-wall stove pipe. But quite every time a double wall is more beneficial than a single wall stove pipe. It requires less space, keeps the heat inside the pipe as well as more durable in high temperatures. As long as the budget isn’t an issue, we recommend you go for a double-wall stove pipe.
Is double wall stove pipe better for fire?
A double-wall stove pipe is more durable in high temperatures. It has an internal air-cooling structure. So while blowing off the air through the pipe, it cools off the outside of the pipe. On the contrary, a single wall stove pipe becomes too hot and maintains the temperature throughout the pipe. Yet whether it is a single wall or double wall stove pipe, the main reason for a chimney to catch fire is the lack of clearance and stored creosote. If the creosote on the chimney wall becomes ⅛” to ¼” and has air blowing at 451 degrees Fahrenheit or hotter, it has the possibility to catch fire.
Can I connect a double-wall stove pipe to a single wall?
Yes, you can connect a double-wall stove pipe to a single-wall stove pipe using an adapter. You need to connect the male or female end of the adapter to the double-wall stove pipe and the opposite to the single-wall stove pipe.
Is a double-wall stove pipe necessary?
A double-wall stove pipe is way better when it is used for going through the ceilings or walls. It is more durable in high temperatures. It keeps the hot air inside the pipe with its two-layered walls. On the contrary, a single wall stove pipe gets too hot and can cause damage to the attached materials. So, using a double-wall stove pipe is necessary for certain purposes.
Does the crimped end of a stove pipe go up or down
The crimped end of a stove pipe goes down where the pipe is attached to the Stove. So the creosote stays inside the stove when the chimney cools down. It protects the chimney from storing creosote that can result in chimney fire at a certain temperature.
Can I run a wood stove pipe through a wall?
You can run a double or triple-wall stove pipe through a wall if necessary. But stove pipes are designed to be used in an interior property. Yet you can run a double wall wood stove pipe through a wall using a kit called “ Thimble ”. We recommend using a chimney pipe rather than a stovepipe while going through a wall.
Is single-wall stove pipe safe?
No, a single-wall stove pipe is not safe compared to a double-wall stove pipe or chimney pipe for a chimney installation. As it is a one-layered simple black-painted pipe without any internal air-cooling system, it fails to keep the high temperatures inside the pipe. That causes damage to the nearly attached materials.
How hot does double wall wood stove pipe get?
A double wall stove pipe is designed to withstand about 1700-2100°F inside the pipe. But according to some studies, the outside can get up to 110 to 250°F maximum.
