and fan control must also be located in the upper position on the casing when the
furnace is placed in the final installed position, refer to Figure 7. If the control
must be relocated, remove the cover of the control to gain access to the
mounting screws. Remove the mounting screws and the control. Insert the
control into the alternate mounting hole in the casing and mark the screw
locations. Drill pilot holes for the new screws. Install the control in the new
mounting location and secure it with the mounting screws. Replace the cover of
the control. A metal, snap-in cap is furnished with the furnace to close the
unused hole, for the control, in the casing.
