The HHT SL1100 Wood Venting System is intended to effectively vent wood-burning stoves and appliances. A critical component of this venting system is the Chimney Pipe Straight Section. This straight section is a vital part of the venting setup, and here's what you need to know about it:

  1. Material and Construction: Chimney Pipe Straight Sections for the HHT SL1100 Wood Venting system are typically made from durable and corrosion-resistant materials like stainless steel. This ensures that they can withstand the high temperatures and potentially corrosive byproducts produced during the combustion of wood.

  2. Diameter and Length: The specific diameter and length of the chimney pipe straight section can vary depending on your wood-burning appliance's requirements and the venting system's design. These sections come in various sizes, so it's crucial to select the right one that matches your appliance and the installation needs.

  3. Seamless Design: Most chimney pipe straight sections are designed to be seamless, which minimizes the risk of leaks and ensures an efficient, unobstructed flow of exhaust gases from your wood-burning stove or appliance.

  4. Easy Installation: The straight sections are often equipped with secure locking mechanisms or twist-lock connections, making them relatively easy to assemble and install. Follow the manufacturer's guidelines and local building codes to ensure a safe and reliable installation.

  5. Compatibility: These chimney pipe straight sections are designed to work seamlessly with the HHT SL1100 Wood Venting system, ensuring proper draft and venting performance for your wood-burning appliance.

  6. Insulation Options: Depending on your installation requirements, some straight sections may come with insulation. Insulated chimney pipe sections help to maintain the necessary temperature inside the venting system and reduce the risk of creosote buildup, which can be a potential fire hazard.

  7. Accessories: When installing a chimney pipe straight section, you may also need additional accessories such as adjustable elbows, storm collars, support brackets, and rain caps to complete the venting system and ensure it's weather-resistant and safe.

Remember that proper installation and maintenance of the HHT SL1100 Wood Venting system, including the chimney pipe straight section, are crucial for safety and efficiency. It's essential to consult the manufacturer's guidelines and local building codes or regulations, and it's often a good idea to have a professional installer or chimney sweep handle the installation to ensure it's done correctly.

Choosing The Perfect Venting System for Your Fireplace

To ensure security, effectiveness, and usefulness, it is crucial to select the ideal venting system for your fireplace. There are several factors to consider when selecting a venting system, including the type of fireplace, fuel source, local building codes, and your personal preferences. Here's a step-by-step guide to help you make the right choice:

Determine the Type of Fireplace:

  • Wood-Burning Fireplace: If you have a traditional wood-burning fireplace, you'll need a chimney or venting system designed to handle the combustion byproducts and smoke.
  • Gas Fireplace: Gas fireplaces can be vented through either a direct vent or a ventless (vent-free) system. Your choice will depend on local regulations and your heating needs.

Understand Venting Options:

  • Chimney: A traditional masonry or metal chimney is suitable for wood-burning fireplaces. Ensure it is in good condition and meets local codes.
  • Direct Vent: This system is commonly used for gas fireplaces. It has a sealed combustion chamber and draws fresh air from outside for combustion while expelling exhaust gases outside through a dedicated vent pipe.
  • Ventless (Vent-Free): Ventless gas fireplaces don't require a chimney or external venting. They burn gas cleanly and release heat and moisture into the room. However, they are subject to strict regulations in some areas due to air quality concerns.

Check Local Building Codes:

  • Before making a decision, check local building codes and regulations. Some areas have strict requirements for venting systems to ensure safety and air quality. Compliance with these codes is crucial.

Consider Efficiency:

  • Choose a venting system that maximizes energy efficiency. Direct vent systems are more efficient than traditional chimneys because they minimize heat loss.

Safety Considerations:

  • Safety should be a top priority. Ensure that the venting system is correctly installed and maintained to prevent carbon monoxide leaks and other hazards.

Aesthetics and Design:

  • The venting system should complement your home's design and aesthetics. It should be as unobtrusive as possible while still performing its function.

Professional Installation:

  • It's strongly recommended to have your venting system installed by a qualified professional who is familiar with local codes and regulations.


  • Regular maintenance is essential to keep your venting system working efficiently and safely. Schedule annual inspections and cleanings, especially for wood-burning chimneys.


  • Consider your budget for both the initial installation and ongoing maintenance. While ventless systems may be cheaper to install initially, they may have higher operating costs due to increased gas consumption.

Environmental Impact:

  • If you're concerned about environmental impact, consider the emissions associated with your chosen venting system. Wood-burning fireplaces, for example, can release particulate matter and other pollutants into the air.

Ultimately, your individual circumstances, such as the sort of fireplace you have, your local laws, and your own preferences for aesthetics and efficiency, will determine the ideal venting system for your fireplace.

A Comprehensive Guide to Buying a Fireplace Venting System

A fireplace venting system is an essential part of your fireplace that makes sure that smoke and combustion byproducts are securely removed from your home while providing a supply of fresh air for burning. Whether you're installing a new fireplace or upgrading an existing one, this comprehensive buyer's guide will help you understand the various venting options and make an informed decision.

1. Types of Fireplace Venting Systems:

There are three main types of fireplace venting systems:

  • Chimney Venting: Traditional masonry fireplaces typically have a brick or stone chimney. They rely on natural convection to draw air in and expel smoke out through the chimney. This type of venting is suitable for wood-burning fireplaces.

  • Direct Venting: This is a sealed system that draws combustion air from the outside and expels exhaust gases through a vent pipe. Direct vent fireplaces are highly efficient and can be used with various fuel types, including gas and propane.

  • Ventless or Vent-Free Venting: These fireplaces do not require a venting system, as they are designed to burn fuel cleanly enough that the combustion byproducts can be safely released into the room. They are typically gas-powered and can be installed almost anywhere.

2. Choosing the Right Type:

  • Consider Your Fuel Type: Determine whether you want a wood-burning, gas, or electric fireplace. Your fuel choice will influence the type of venting system you need.

  • Efficiency and Convenience: Direct vent and ventless fireplaces are typically more energy-efficient and easier to install than traditional chimneys. Consider your preferences for convenience and energy efficiency.

3. Sizing and Location:

  • Calculate Heating Needs: Determine the heating capacity you need based on the size of the room or area you want to heat. This will help you choose an appropriately sized fireplace and venting system.

  • Location: Decide where you want to install your fireplace. The location may impact the type of venting system you can use and the venting route.

4. Venting Materials:

  • Chimney Materials: If you're using a traditional chimney, consider the type of materials you want for its construction, such as brick, stone, or metal flue liners.

  • Vent Pipe Material: For direct vent fireplaces, the vent pipe is typically made of aluminum or stainless steel. Ensure the materials are suitable for your fuel type and meet local building codes.

5. Installation and Safety:

  • Professional Installation: Proper installation is crucial for safety and performance. Hire a certified technician or contractor experienced in fireplace venting systems.

  • Clearances: Ensure proper clearances to combustibles are maintained as per the manufacturer's guidelines and local building codes.

6. Venting Accessories:

  • Termination Caps: These protect the vent opening from weather and pests.

  • Chimney Liners: If you have a masonry chimney, consider installing a stainless steel liner to improve efficiency and safety.

7. Maintenance and Cleaning:

  • Regular Inspections: Schedule regular inspections and cleaning to ensure your venting system is functioning correctly and free from debris or blockages.

8. Legal and Safety Considerations:

  • Local Codes and Regulations: Check with your local authorities to ensure compliance with building codes and regulations regarding fireplace venting.

  • Carbon Monoxide Detectors: Install carbon monoxide detectors in your home, especially if you have a gas fireplace.

9. Budget Considerations:

  • Initial Cost: Consider both the upfront cost of the fireplace and venting system, as well as the ongoing operating costs (fuel, maintenance, etc.).

10. Aesthetics:

  • Design and Style: Choose a venting system that complements your home's aesthetic and blends well with your interior design.

Remember that safety should always be your top priority when selecting and installing a fireplace venting system. Consult with professionals and follow manufacturer guidelines and local regulations to ensure a safe and efficient installation.
