EL296UHE Gas Furnace

The EL296UHE Category IV gas furnace is shipped ready for installation in the upflow or horizontal position. The fur­ nace is shipped with the bottom panel in place. The bot­ tom panel must be removed if the unit is to be installed in horizontal or upflow applications with bottom return air.

The EL296UHE 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 ap­ plications. A conversion kit (ordered separately) is re­ quired for use in propane/LP gas applications.

NOTE - In Direct Vent installations, combustion air is taken 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 are discharged outdoors. See figures 1 and 2 for applications in­ volving roof termination.
