Suburban RV Furnace Parts
All Suburban furnaces that are installed in recreational vehicles are classified as direct vent sealed combustion furnaces. However, forced draft furnaces use sealed combustion chambers that are vented to the outside atmosphere. The intake air that is used for combustion is also taken from outdoors and is fully isolated from the room air. A motor is used to drive an impeller wheel that in turn draws air into the combustion chamber to support combustion and in turn force the exhaust gases through the furnace chamber to the atmosphere. A second impeller wheel (driven by the same moor but completely isolated from the combustion air) is then used to circulate room air across the furnace chamber where it is heated. A blower is then used to force hot air into the designated living area either through a duct system or front grille on the furnace cabinet if you are using a direct discharge model.
