Features a simple modular water path which minimizes water pressure drop. The modular water path design makes maintenance and service easier to perform.
• Condensing technology uses the energy from the exhaust gases which lowers the temperature of the gases going out of the flue. It can therefore utilize PVC venting, which is not only easier to install, but less expensive.
• 2” PVC, CPVC, Polyprophylene Venting Up To 60’
• 2” venting option allows for a flue to be pulled through an existing vent.
• 3” vents can be used up to 150’ with standard 2” x 3” adapters.
