Description

Reznor's RP duct furnaces are built with a weatherized cabinet and control compartment. Each model is completely pre-packaged, factory wired, and fire tested. Units are designed for use with standard air handling systems in air conditioning, heating or makeup air applications.
Can be installed upstream or downstream from cooling coils.

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.
