The GUH95C Category IV gas furnace is shipped ready for
installation in the upflow or horizontal position. The furnace
is shipped with the bottom panel in place. The bottom panel
must be removed if the unit is to be installed in horizontal
or upflow applications with bottom return air.
The GUH95C can be installed as either a Direct Vent or a
Non-Direct Vent gas central furnace.
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 flue gases are discharged outdoors. In
Non-Direct Vent installations, combustion air is taken from
indoors or ventilated attic or crawlspace and flue gases
