The performance of any building is dependent upon the design, installation, and workmanship
of the entire building system. Pella Corporation strongly recommends consulting an
experienced architect, contractor or structural engineer prior to installation of Pella products.
The individual (building owner, architect, contractor, installer and/or consumer) responsible
for the project must take into account local conditions, building codes, inherent component
limitations, the effects of aging and weathering on building components, and other design
issues relevant to each project.
The determination of the suitability of all building components for each project, as well as the
design and installation of flashing and sealing systems, are the responsibility of the building
owner, architect, contractor, installer and/or consumer.

ROUGH OPENING
PREPARATION:
A. Confirm the opening is plumb and level.
Note: It is critical that the bottom is level.
B. Confirm the door will fit the opening. Measure all
four sides of the opening to make sure it is 3/4"
larger than the door in width and 1/2" larger in
height. Measure the width at the top, bottom, and
center. Measure the height at the far left side, the far
right side, and in the center.
Note: 1-1/2" or more of solid wood blocking is
required around the perimeter of the opening.
Fix any problems with the rough opening before
proceeding.
