Dura-Vent DuraFlexAL Aluminum Chimney Liner


DuraFlexAL is Dura-Vent's flexible aluminum liner for gas burning appliances (not for use with wood, oil, pellet or coal burning appliances).  If you have a straight down installation DuraFlexAL is a good choice, especially if price is a concern.  We recommend you study the brochure and installation instructions to become familiar with the product.  Follow manufacturer recommendations whenever applicable. Never use a chimney liner that is smaller in diameter than the flue size of the appliance it is being connected to.  See DuraFlexSS for wood, oil, pellet or coal burning appliances.
