Outdoor Gas Duct FurnacesOutdoor Power Exhausted (HFP) Gas Duct Furnace
For Space Heating For Dehumidification Systems
The outdoor duct furnace was designed as a building’s heating system. Available in 11 power exhausted model sizes, the unit covers a wide variety of applications. They have input ranges from 75,000 to 400,000 Btu/Hr and can operate on either natural or propane gas. The airflow direction can be specified when ordering the unit. The duct furnace is certified for location downstream from dehumidifier and has holes to drain any condensate that may form onto the roof.
