Install Sill Pan
1. Install a sill pan in a weatherproof manner on the rough sill (refer to
ASTM 2112 for types of sill pans). Always allow water to drain out of
the pan and onto the building wrap, drainage plane or to the exterior.
2. If installing a metal sill pan on concrete, cut a piece of self-adhered
ashing the length of the sill pan and adhere it to the entire bottom
surface where the pan will sit on theconcrete.
3. Set the sill pan in the rough opening, aligning the front edge (for
continuous slab) or folded down edge (for step-down) with the
exterior of the rough opening.
4. Mark a line across the front and back of the sill pan.
5. Apply a 3/8" continuous bead of sealant across the sill pan back dam,
in each corner and over the ashing joints asshown.
6. Tilt patio door into the rough opening. Make sure the back of the
door makes solid contact with the sealant. Tool the sealant until
smooth. Add more sealant if necessary to create a continuous seal.

7. Apply three 3/8" beads of sealant between the lines.
8. Place the sill pan in the rough opening. Firmly press the sill pan into
the sealant with a J-roller.
