We Won’t Overlook Your Smoke Chamber!
What is A Smoke Chamber?
The smoke chamber is one of the most important and overlooked areas of your chimney system. It is the area just above the firebox that acts as the gateway to the chimney flue. The main job of the smoke chamber is to guide smoke and toxic gases up into the chimney where they can safely exit the home. If the masonry of the smoke chamber is damaged, or if the dimensions of this part of your chimney are not correct, it can make using your fireplace inefficient and dangerous.
Unfortunately, many chimneys have smoke chambers that are damaged and not up to current standards. Here are some of the recommendations that the National Fire Protection Association (NFPA) lays out to ensure that smoke chambers are functioning properly:
- A smoke chamber should not be taller than the fireplace opening width
- A smoke chamber should not be deeper than the fireplace opening
- Smoke chamber walls should not incline more than 45 degrees from vertical
- The walls of the smoke chamber should be smooth to help reduce turbulence that can upset air flow
- The flue should start directly at the top of the smoke chamber and should be free of radical offsets or bends
Is your smoke chamber up to par?
Parging Can Make All The Difference
When it comes to repairing or correcting problems with a smoke chamber, parging can go a long way. Parging is the process of applying a specialized refractory mortar to the walls of the smoke chamber to give it a smooth surface. This allows the air and smoke to flow properly; it can also help redefine the dimensions if a smoke chamber was not built correctly.
Are there cracks and gaps in your smoke chamber? Parging it smooth can also help seal any voids in the masonry that could otherwise allow smoke, gases, and heat to escape into the surrounding walls and home. Parging is so incredibly beneficial that most building codes now require smoke chamber walls to be parged.
