The All-Fuel Chimney Pipe is a system designed for low-heat residential appliances that are fueled by wood, coal, oil, or gas. This type of chimney is commonly known as a "Class A chimney" or "Factory-built chimney" and is frequently used for free-standing stoves, furnaces, and fireplaces. The product is offered in double-wall or triple-wall construction and is listed to UL 103, UL 103HT, ULC S629, or ULC S604.

It is important to note that the inside diameter is used to choose and classify all Stove & Chimney Pipe, and that components from different manufacturers and brands should not be mixed.
