STEP 1: CUT OPENING IN GASKET

Remove an 8 1/8" portion of the weather seal gasket from the bottom right surface of the plenum.

To remove: Cut the gasket in the lower right corner of the plenum. Then make a second cut 8 1/8" from the

right corner. The gasket should peel away from the plenum leaving a clean mounting surface (See detail A).

STEP 2: SEAL AND SET PAN

Prior to placing the drain pan into the opening run a 1/4" bead of sealant the entire width of the removed

gasket. The pan should be placed against the right edge of the plenum and the secondary overow lip

inserted into the plenum NO DEEPER THAN 1.5 INCHES to prevent water leaks (See Detail B).
