Enhance Your Safety With Professional Masonry Chimney Relining for Gas Appliances by Northeastern Masonry & Chimney
More and more homeowners are opting to convert their masonry fireplaces to gas-burning appliances like gas log sets, gas fireplaces, or gas inserts. This switch is driven by a variety of factors, including the mess-free nature of gas-burning appliances, which eliminates the need for loading, cleaning, and dealing with ash. Gas-burning appliances also offer more convenience, as they require no chopping, hauling, or storing of wood. With a simple push of a button, a cozy fire can be enjoyed without the hassle of building one. Gas is a cleaner-burning fuel compared to wood, making it an attractive option for eco-conscious homeowners, and these appliances are low-maintenance. This makes them ideal for busy individuals who value a hassle-free and efficient heating solution.
With all the bonuses of having a gas appliance, it’s easy to forget that these machines and their venting systems are still under constant stress and require regular maintenance.

Can a Chimney Liner Improve the Efficiency of My Gas Appliance?
A properly sized and installed chimney liner can significantly boost the efficiency of your gas appliance. Gas-burning systems produce cooler exhaust compared to wood or oil appliances, which means the chimney flue needs to be appropriately sized to maintain adequate draft. If the flue is too large, the gases cool too quickly, leading to condensation buildup inside the chimney. This moisture can mix with acidic byproducts, causing corrosion and reducing the liner’s lifespan.
A correctly fitted liner prevents these issues by ensuring that the exhaust stays warm enough to exit the chimney efficiently. This not only improves the performance of your gas appliance but also minimizes the risk of condensation-related damage to the chimney structure. Relining is a smart investment that enhances safety and helps your appliance operate as intended, delivering consistent warmth and comfort to your home.
What Type of Liner Is Best for Chimneys Venting Gas Appliances?
When it comes to gas appliances, stainless steel liners are the usual go-to option. These liners are durable, resistant to corrosion, and designed to handle the cooler exhaust temperatures associated with gas-burning systems. In contrast, older clay liners or liners designed for wood-burning systems may not perform well with gas appliances due to their inability to withstand acidic condensation over time.
If you have a high-efficiency gas appliance, the liner material becomes even more important. These systems produce exhaust that is not only cooler but also higher in moisture and acidic content, making stainless steel or aluminum liners a better choice. Flexible stainless steel liners are often used to retrofit older chimneys, as they can accommodate bends and irregularities in the flue.
The Northeastern Masonry & Chimney team will assess your chimney and appliance to recommend the best liner material and size to ensure performance and longevity.
Can a Gas Appliance Share a Chimney With a Wood-Burning or Oil-Fueled Appliance?
Sharing a chimney flue between different types of appliances is not recommended and – in most cases – violates building codes and safety standards. Gas appliances vent differently from wood-burning or oil-fueled systems, and combining these exhausts in the same flue can create a host of problems.
For example, gas exhaust is cooler and lighter than wood or oil combustion byproducts. If these gases are vented into a flue already occupied by heavier wood or oil smoke, they may fail to exit properly, leading to backdrafting or the accumulation of harmful gases like carbon monoxide. Additionally, the acidic moisture from gas exhaust can mix with soot from wood or oil combustion, accelerating corrosion and compromising the chimney’s integrity.
Each appliance should have its own dedicated liner to ensure safe and efficient venting. Our team can install separate liners for your appliances or reconfigure your system to meet current safety standards.
What Are the Differences Between Relining for High-Efficiency and Older Gas Appliances?
High-efficiency gas appliances have unique venting requirements that often necessitate relining. These systems extract more heat from the combustion process, resulting in cooler exhaust temperatures. While this is great for energy savings, it poses challenges for venting, as cooler gases are more prone to condensation inside the flue.
For older gas appliances, the exhaust temperature is typically higher, meaning the chimney draft is stronger and condensation is less of a concern. However, older systems may still require relining if the original liner has deteriorated or is made of materials incompatible with modern models.
In some cases, additional insulation is added around the liner to prevent the gases from cooling too quickly. At Northeastern Masonry & Chimney, we understand the nuances of relining for both high-efficiency and older gas appliances, ensuring your chimney system is set up to reflect your specific needs.
Can an Oversized Chimney Lead To Problems With Venting Gas Appliances?
Many homeowners are unaware of how crucial flue size is with gas-burning appliances. If you’ve had a gas-burning appliance installed in your masonry fireplace, your existing flue is likely too large for the new appliance. When high-efficiency gas appliances vent through oversized masonry chimneys, the acidic gases and vapor have more time to cool and settle on the masonry walls. Over time, this acidic condensation will eat away at the masonry, causing the entire system to suffer in regard to efficiency and function.
