The  furnace  is  equipped  for  installation  in  natural  gas 
applications.  A  conversion  kit  (ordered  separately)  is 
required for use in propane/LP gas applications.

from  outdoors  and  ue  gases  are  discharged  outdoors. 
In Non-Direct Vent installations, combustion air is taken 
from  indoors  and  ue  gases  are  discharged  outdoors.
