IMPORTANT

The unit will not vent properly with the flue transition pointed down in the 6 o’clock position.

The combustion air inducer may be rotated clockwise or counterclockwise by 90° to allow for top or side vent discharge in all applications. When the unit is installed, the flue transition must be in the 9 o’clock, 12 o’clock or 3 o’clock position.

If necessary reposition the combustion air inducer, pressure switch and/or make-up box as needed per the following steps. See Figures 16 through 22.

1.Remove the four mounting screws (Figure 15) which secure the combustion air inducer / pressure switch assembly to the orifice plate. Lift the assembly and rotate it 90° clockwise or counter clockwise to either the 3 o’clock position. Resecure with four secrews. Gasket should be left in place.

2.Use tin snips to cut preferred opening on the cabinet for repositioning the flue outlet. Use the cut-out piece as a cover plate to patch unused opening on cabinet.
