Proper chimney pipe installation is crucial to ensuring a safe and efficient heating system. This process not only guarantees the correct flow of combustion gases but also protects your home or space from potential risks. In this article, we will explore the key steps for installing chimney pipes, common mistakes to avoid, and Exojo’s recommended products to optimise performance.
Essential Steps for Installing Chimney Pipes
1. System Planning
Before starting the installation, it is important to carefully plan the route of the pipes. Ensure that the path is as straight as possible, as excessive bends can hinder airflow and make smoke extraction difficult. Calculate the necessary pipe lengths and identify key points such as joints and outlets.
2. Selecting the Right Components
Choosing pipes designed for the specific fuel type and operating conditions is crucial. For example, at Exojo, we recommend:
- Exoleña and Exoleña Premium for wood-burning appliances.
- Exopellet for pellet-burning stoves.
- Exoinox single-wall for gas boiler installations in internal sections.
- Exoinox DW and Exoblack DW for external sections.
- Exogalva for ventilation systems.
3. Assembling the Pipes
- Begin by assembling the pipes from the base (stove or chimney) towards the exit.
- Connect the male and female ends of each section, ensuring the female end is always on top.
- When changing direction, keep horizontal sections as short as possible.
- When passing through floors or ceilings, switch to double-wall pipes before returning to single-wall pipes when feasible.
- For external sections, always use double-wall pipes.
- Secure the pipes using brackets to ensure a firm and stable installation.
- Complete the installation by fitting the terminal piece. Ensure that smoke evacuation is carried out through the roof, maintaining the required clearance distances from the chimney termination, the roof, and other obstacles such as buildings, walkways, or neighbouring structures.
Installing Additional Accessories
- Anti-downdraught terminals: Prevent airflow issues. These should always be placed on the roof at the final exit point.
- Fixing brackets: Secure the pipes by inserting them into the bracket and attaching it firmly to the wall.
- Inspection modules: In systems with a rear smoke outlet, it is essential to install a T-module at the beginning of the system.
Final Testing and Adjustments
Once the installation is complete, perform thorough tests to check for any leaks and ensure the system functions correctly. Inspect the joints and verify that the airflow is constant throughout the system.
Common Mistakes and How to Avoid Them
With over 50 years of experience, we have identified several common installation mistakes:
✔ Using non-certified materials: Choosing low-quality pipes can compromise safety and durability. Always opt for certified products.
✔ Excessive bends: Too many bends reduce system efficiency and can cause soot build-up. Keep the installation as straight as possible and use 45° elbows instead of 90° elbows, as they allow for better airflow.
✔ Lack of maintenance: Installing inspection modules facilitates regular cleaning and helps prevent long-term issues.
✔ Infrequent cleaning and inspections: To ensure efficiency and longevity, schedule at least one annual maintenance check.
✔ Incorrect pipe orientation: Many installations are performed incorrectly. Always remember that the female end should face upwards.
The Key to a Successful Installation
Chimney pipe installation can be straightforward and effective if the correct steps are followed and high-quality products are used. At Exojo, we provide certified solutions that ensure safety, efficiency, and durability for all types of chimney installations.
