ABSTRACT:
The present invention encompasses a modular chimney having a fireplace, a smoke chamber, and a plurality of modular blocks, forming at least one stack of blocks, the stack of modular blocks defining a chimney passage that is in fluid communication with the smoke chamber for the passage of combustion products. Alternatively, in a second embodiment, the modular chimney may also include a plurality of angled blocks, forming at least one angled stack of angled blocks, the angled stack of angled blocks defining an angled chimney passage that is in fluid communication with the smoke chamber and the chimney passage. The modular chimney may also have a top plate that is disposed onto the upper surface of the smoke chamber and, upon which, the stack of modular blocks or the stack of angled blocks may be disposed, and the chimney may also have a ledger block, interposed between two stacks of modular blocks, so that a desired exterior surface treatment may be supported when it is applied to the exterior of the modular chimney. The modular sections of the top plate, the modular block, the angled block, and the ledger block are engaged in a nesting relationship that serves to orient the respective modular sections, to provide structural support to the modular sections and the modular chimney, and to provide a physical obstruction to the passage of flame, hot gases, and smoke through the joints of the modular sections when the sections are physically joined and mortared together.
