Reznor's V3 Series UDAS gas-fired separated combustion unit heaters are available in 14 sizes ranging from 30,000 to 400,000 btu/h gas input (Sizes 30-125 are approved for residential application). Model UDAS heaters are designed for 82 to 83 percent thermal efficiency and are approved for installation in the United States and Canada by the Canadian Standards Association (CSA). The first ever separated combustion system in the commercial/industrial heating industry was introduced on a Reznor heater in the 1960's, and that proven technology is continued in this new separated combustion product. Model UDAS separated combustion units require installation of a specially designed combustion air/vent system including the unique concentric adapter box that allows for only one building penetration for both the vent and combustion air.
