rear of the unit carefully insert the manual reset high limit through the
fl ue pipe opening in the rear cabinet panel. Mount the high limit to
the economizer bracket as shown in Figure 3.

Place the small end of the vent adaptor through the vent pipe opening
in the rear cabinet panel. Position the vent adaptor so the high limit
