The EcoFlex 90+ System packaged fan-powered flue gas economizer features a patent-pending design and can be installed in any part of the chimney,


including horizontally or vertically. It can be used in conjunction with any gas fired heating appliance — condensing or non-condensing, which makes the unit suitable for use with draft hood and draft-diverter equipped heating appliances as well as allowing multiple boilers to share a single economizer.
