ULTRABlack is designed to be used as a connector between a freestanding oil, wood or coal burning stove and a masonry or metal chimney. There are four primary advantages to ULTRABlack over single wall connector pipes:

• It offers reduced clearance to combustible materials.
• It is designed to last the lifetime of the stove and/or chimney system.
• It offers reduced creosote formation.
• It is certified for use with mobile home stoves.

Clearance to Combustible Materials
ULTRABlack is certified for 6" clearance with the following exception. When ULTRABlack is used as the connector on a mobile home certified stove the clearance is determined by the installation instructions for the specific stove model being installed.
