Reznor's V3 Series UDAS gas-fired separated combustion unit heaters are available in 14 sizes ranging from 30,000 to 400,000 BTUH gas input (Sizes 30-125 are approved for residential application). Model UDAS heaters are designed for 82-83% 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. Note: Selection of either a horizontal or vertical combustion air/vent kit is required. Video Link: https://www.youtube.com/watch?v=WVtYBqJIWEA
