The company offers a variety of chimney and vent products. They include a complete line of B-vent, Corr/Guard® special gas vent, solid fuel chimney and pellet chimney, flexible chimney liners, and fire dampers. The round and oval Type-B vent is listed by Underwriters Laboratories (UL) for use with approved category 1 gas furnaces, heaters, and boilers. They offer 360-degree rotation of small-diameter fittings using swivel tees, wyes, and elbows. Corr/Guard comes in several diameter sizes. The products in the pellet/biomass line have joint connections that utilize a Positive Twist-Lock and a Sure-Lock locking tab for easy installation (and disassembly if required). The pellet/biomass joint connections also include a rope gasket to prevent fly ash leakage, and the elbow gores are sealed at the factory. Chimney liners can be used to help masonry chimneys from deteriorating due to acidic gases. Available fire dampers include static curtain-type fire dampers and dynamic curtain-type fire dampers. Orders for standard vent products can be shipped within one to two days. When ordered, the customer receives an email confirmation within an hour, then the order is pulled and shrink-wrapped on a skid.
