The compact Patriot 80 series oil furnaces comes in a variety of configurations to fit virtually anywhere, including utility rooms, alcoves, closets, crawl spaces and attics. In addition to upflow, downflow/horizontal, and front flue versions, models come in heat only and heating / cooling combinations. Patriot 80 furnaces feature foil-faced fiberglass insulation, a ceramic high temperature combustion chamber, and a harmonically balanced blower which keeps operating noise to a minimum.

(Note regarding air conditioning: If you will be adding a Goodman air conditioner or heat pump system to an oil furnace, you must replace the air conditioning evaporator coil's drain pan with a high temperature one such as Goodman models HTP-A, B, C or D. Please call Alpine for assistance.)

Please read this Important Safety Notice.
