INSTALLATION INSTRUCTIONS
for Wood Patio Doors with Exterior Trim or Nailing Fin (JII026)
Newer construction methods have led to an increase in air and water 
tightness in buildings. This frequently leads to negative air pressure 
inside the home, which can draw water through very small openings. Our 
installation method seals the patio door to the weather barrier (typically 
building wrap) and uses a sill pan to capture and drain incidental water 
from under the patio door.
Thank you for selecting JELD-WEN products. Attached are JELD-WEN’s 
recommended installation instructions for wood patio doors with 
exterior trim or nailing n. Read these instructions thoroughly before 
beginning. They are designed to work in most existing applications, 
however; existing conditions may require changes to these 
instructions. If changes are needed, they are made at the installer’s 
risk. For installations other than indicated in these instructions, contact 
a building professional. Areas such as Florida and the Texas TDI region 
have different anchoring requirements based on product certification. 
For information on specific products, visit www.floridabuilding.org 
or www.tdi.texas.gov and follow the anchoring schedule given in 
the drawings for the product instead of the anchoring schedule in 
this document.
IMPORTANT INFORMATION AND GLOSSARY
LANDINGS
These instructions 
cover two patio door 
sill conditions: the 
step-down landing 
and the continuous 
slab landing. The 
installation methods 
vary slightly between 
landing types.
Not all patio door types may be installed into every wall condition in all 
areas. Consult your local building code official for applicable building 
codes and regulations. Local building code requirements supersede 
recommended installation instructions.
Please Note! Any patio door installation where the sill is higher than 
35 feet above ground level or into a wall condition not specically 
addressed in these instructions must be designed by an architect or 
structural engineer. Failure to install square, level and plumb and on a 
at surface (without twist or warp) could result in denial of warranty 
claims for operational or performance problems.
Note to Installer: Provide a copy of these instructions to the building 
owner. By installing this product, you acknowledge the terms and 
conditions of the limited warranty as part of the terms of the sale.

Self-Adhered Flashing (SAF)
