Redesigned LP gas and electronic ignition furnaces are now more efficient and quieter with a new burner and blower assembly. Annoying frequency spikes and overall noise have been removed with an increase in airflow. Compact, low profile, twelve volt DC furnaces can be installed vertically to better utilize space. All controls and crucial components are easily accessible from outside your RV, which eliminates the need to remove the furnace. Unlike competitive units, there is no carbon build-up maintenance required. It can be configured for side or bottom discharge. Cut-out size: 7-1/2" H x 19-1/2" W. Doors sold separately. 1/box.
