Wood Stove Pipe Installation: Straight Up or Flexible?

A wood stove pipe does not have to go straight up, but it is recommended to maximize the efficiency of your wood stove. A straight vertical pipe provides the least amount of resistance for the smoke and exhaust gases to rise up and exit the chimney.

When installing a wood stove pipe, it is important to consider the path and slope of the pipe to ensure proper ventilation and prevent potential hazards such as creosote build-up and chimney fires. A wood stove pipe that has too many elbows and turns can create obstructions that interfere with the airflow.

This can cause stove pipes to overheat and become a fire hazard. It is therefore important to follow the guidelines set by building codes, the manufacturer’s instructions, and consult with a professional installer to ensure proper installation of a wood stove pipe.

Straight Up Wood Stove Pipe Installation

For those who don’t have the space or the budget for a traditional fireplace, a wood stove is an excellent alternative. It’s cheaper, easier to install and more efficient when it comes to heating your home. But when it comes to wood stove pipe installation, it’s important to do it correctly.

In this section, we’ll explore the essentials when it comes to straight up wood stove pipe installation.

  • Straight up wood stove pipe installation means that the chimney runs straight up and through the roof of your home. This method is the most common and simplest way of installation.
  • The first thing to consider when installing a wood stove is the location of the stove. It should be installed in a central location in the home, away from combustible materials.

  • The chimney should extend at least three feet above the roofline.
  • The minimum clearance from combustible materials for the chimney is two inches.
  • Chimneys should never pass through an attic or roof space where there is no fire protection.
  • The chimney pipe should be kept straight with no more than two bends, and each bend should not exceed 45 degrees.
  • The chimney pipe should never be installed horizontally.
  • You should install a chimney cap to prevent rain, debris, and animals from entering the chimney.
  • It’s important to follow all the manufacturer’s guidelines when it comes to materials and installation instructions.

Straight up wood stove pipe installation is an excellent way to heat your home while remaining energy efficient. By following all the necessary safety guidelines and consulting with a professional when necessary, you can install a wood stove and ensure your family’s safety.

Flexible Wood Stove Pipe Installation

Wood stoves are an excellent way to heat a home, and many homeowners believe they must install straight vent pipes. Flexible wood stove pipes are available, but is it necessary to make the switch? Let’s explore the basics of flexible wood stove pipe installation, highlighting the benefits and drawbacks to make an informed decision.

The Basics Of Flexible Wood Stove Pipe Installation

Installing a wood stove pipe is crucial to ensure proper ventilation and safety. A flexible pipe is made of stainless steel, and it bends according to the angle you need for your installation. Here are the basics you should consider.

  • A flexible pipe’s length ranges from 25 to 100 feet.
  • The diameter is usually 6 inches, but other sizes are available.
  • Flexible pipes can bend up to 90 degrees, whereas straight pipes cannot.

Benefits Of Using Flexible Pipes Over Straight Pipes

Flexible wood stove pipes offer several benefits that make them worth considering, such as:

  • Flexible pipes are ideal for tight spaces since they can bend and curve more easily than a straight pipe.
  • You don’t have to cut the pipe to fit your installation.
  • The installation time of a flexible pipe is usually shorter than that of a straight pipe.
  • Flexible pipes are more affordable than traditional straight pipes.

Drawbacks And Limitations Of Flexible Pipes

Although flexible wood stove pipes offer several benefits, they also come with a few limitations and drawbacks.

  • Flexible pipes require more support than straight pipes due to their lack of rigidity.
  • They cannot be used for extended horizontal runs. The pipe must be installed at a slope up to the roofline.
  • The bends and curves of a flexible pipe must be gentle and gradual. Sharp bends can cause kinks, constrictions, and poor air flow.
  • Flexible pipes may be unsightly when visible in a room, and they do not have the same aesthetic appeal as a traditional straight pipe.

As with all home projects, it’s essential to understand the installation process and consider the benefits and drawbacks of flexible wood stove pipes carefully. If you have any doubts or concerns, it is advisable to contact a professional for assistance.

Factors To Consider When Choosing Between Straight And Flexible Wood Stove Pipe Installation

When it comes to wood stove pipe installations, there are two main options: straight and flexible. Choosing between the two can be a tough decision, as several factors should be considered before making a final decision. In this section, we will look at some critical factors that should guide a homeowner’s decision between straight and flexible wood stove pipe installations.


The budget is often the first factor to consider when choosing between straight and flexible wood stove pipe installations. Generally, flexible pipes are more expensive than straight pipes due to their additional features, such as the ability to bend and the insulation layer that covers the pipe.

If you’re on a tight budget, a straight pipe may be a cost-effective option.

Home Design

The design of your home plays a significant role in determining the best type of wood stove pipe installation. If your house has multiple levels or twists and turns in the ceiling, a flexible pipe may be the better option.

In contrast, if your home has a single-story design and a vertical chimney, a straight pipe would be more appropriate.

Availability Of Materials

Another vital factor to consider when choosing between straight and flexible stove pipe installation is the availability of materials. Depending on where you live, one type of pipe may be harder to find compared to the other. Generally, straight pipes are easier to come by than their flexible counterparts.

Home Heating Requirements

Finally, you must consider your heating requirements when choosing between straight and flexible stove pipe installations. A flexible pipe may be the best option if you need to direct heat to a specific part of your home. In contrast, a straight pipe may be more appropriate if you have a small home or need to heat only one room.

How To Choose The Right Pipe Diameter For Your Wood Stove

Installing a wood stove is a great way to add warmth and ambiance to your home. However, choosing the right pipe diameter for your stove is crucial for optimal performance and safety. Here are some things to consider:

Factors You’ll Need To Consider

  • Wood stove size: The size of your stove will dictate the diameter of the pipe you’ll need. Smaller stoves require smaller pipes while larger stoves need bigger ones.
  • Chimney height: The height of your chimney can impact the draft in your wood stove. The taller the chimney, the stronger the draft. So if your chimney is short, you’ll need a larger pipe to maintain proper airflow.
  • Draft conditions: The draft conditions in your chimney can also impact the diameter of pipe you need. For example, if the draft is weak, you’ll need a larger pipe to maintain good airflow.

Common Pipe Sizes And Suitability

  • 6-inch pipe: Suitable for small wood stoves and short chimneys.
  • 7-inch pipe: Fits most wood stoves with a heating capacity of up to 1,500 square feet.
  • 8-inch pipe: Ideal for larger stoves with a heating capacity of over 1,500 square feet and taller chimneys.

Choosing the right pipe diameter is crucial for the optimal performance of your wood stove. Consider the size of your stove, the height of your chimney, and the draft conditions to determine the right size. Don’t forget to consult with a professional before starting your installation.


Now that we have come to the end of this article, we can confidently say that a wood stove pipe does not always have to go straight up. Depending on the situation and preferences, a wood stove pipe can be installed with gradual slopes or with bends.

However, it is important to note that the straighter the pipe, the better it works. Any bends or offsets will increase draft resistance and can result in poor stove performance, which can lead to inefficient burning and potentially dangerous creosote build-up.

Therefore, if you are planning to install a wood stove pipe, it is recommended that you consult with a professional to ensure that it is installed correctly and safely, and that it conforms to local building codes and regulations. While a wood stove pipe can be installed non-linearly, the straighter and simpler the installation, the better.
