The M2 series gas furnaces are listed drect vent (sealed combustion) forced air furnaces (type FSP) for use with both natural and propane (LP) gases. A furnace that uses sealed combustion doesn't face any of these problems. Efficiency is defined as the annual heat output of the furnace divided by the annual energy it consumes.This ratio is called the Average Fuel Utilization Efficiency (AFUE). A sealed combustion chamber draws the air it needs through a plastic pipe that runs to the outside of the house. Such units are over 50% more fuel efficient than older heating units and approximately 20% more efficient than a new, mid-efficient unit. Because all furnaces that generate heat with a flame produce carbon monoxide, they need to be vented, and those vented gases allow some of the heat to escape. Damp basements now that is a bigger problem.
