Frequently Asked Questions
Will a chimney extension change how far the outdoor wood boiler needs to be from house?
A chimney extension will not change how far you put your outdoor boiler from YOUR house, but it will impact your comfort if you operate your boiler close to your home and during warmer weather when windows might be open. A chimney extension that extends above your roof line will eliminate this issue. Further, local codes and industry best practices recommend that if your outdoor boiler is less than 300 feet from the nearest neighbor’s home, that you extend the chimney above your neighbor’s roofline.
What are the benefits of a chimney extension?
A chimney extension will save you money and time. You will burn less wood, and the wood you burn will be more efficient. A chimney extension also gets the smoke up in the air better so working around your outdoor boiler is a much more pleasant experience. Everyone in our company who has an outdoor boiler, has the chimney extension and we all love them. It is believed that chimney extensions EXTEND the life expectancy of an outdoor boiler.
How is the chimney extension installed?
The 6” chimney extension is normally just attached to the existing chimney stack, using the Selkirk “Snap-Lock” feature. The 8” chimney extension is normally attached to the “adapter” via the “Snap-Lock” feature, and then the adapter (with the extension attached) is placed INSIDE the 8” chimney and sits down in there.
Do I need to support the chimney extensions in any way?
Chimney extensions up to 4’ in length do not need to be supported. Chimney extensions taller than 4’ will need to be supported by either the “Heavy Duty Roof Brace Kit” on this page, or by wires connected to the top of the extension and secured to firm locations.
