Description
Reznor's X duct furnaces are designed to provide 80% thermal efficiency for indoor application with gravity venting. They are certified for use with natural or propane gas, as specified, in sizes from 75,000 through 400,000 BTUH input.
These models are used as heating components in heating, heating/cooling or makeup air systems and require a separate blower system for air delivery. The furnace has a Thermocore aluminized steel heat exchanger with venturi-design tubes. The die-formed burners are of aluminized steel and include flared ports with a stainless steel insert. The model X furnace is approved for a temperature rise range of 50F to 90F and includes "finger-baffles" for proper air distribution at these lower air volumes.
Easy field conversion is possible for lower temperature rise, higher airflow applications. Check the Installation Manual with unit to determine if your application requires this. To convert the funace for higher airflow, remove air baffles per installation instruction manual.
