Multiple Venting
The EL280UH(X) furnace can vent in multiple positions.
See figure 11.
The make up box may be removed and the combustion air
inducer may be rotated clockwise or counterclockwise 90°
to allow for vertical or horizontal vent discharge in a vertical
or horizontal cabinet position. Remove the four mounting
screws, rotate the combustion air inducer and gasket
(pressure switch should be above the combustion air in-
ducer in all positions), then reinstall the mounting screws.
See unit Installation Instructions for more detail.
IMPORTANT
The combustion air pressure switch must be moved
for horizontal discharge air left position.

In all positions route the wires away from moving parts and the heat of the inducer
motor to prevent damage to the wires. The pressure switch must be installed above
the CAI to prevent moisture from collecting in the hoses or switch.
