Installation Instructions for Typical Wood Frame Construction.

These instructions were developed and tested for use with typical wood frame wall construction

in a wall system designed to manage water. These instructions are not to be used with any other

construction method. Installation instructions for use with other construction methods, multiple

units or bow and bay windows, may be obtained from Pella Corporation, a local Pella retailer, or by

visiting http://www.pella.com. Building designs, construction methods, building materials, and site

conditions unique to your project may require an installation method different from these instructions

and additional care. Determining the appropriate installation method is the responsibility of you, your

architect, or construction professional.

B. Verify the window will fit the opening. Measure all four sides of the

opening to make sure it is 3/4" larger than the window in both width

and height. On larger openings measure the width and height in several

places to ensure the header or studs are not bowed.

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.

6 SEALING THE WINDOW TO THE EXTERIOR WALL CLADDING

When applying siding, brick veneer or other exterior finish material, leave adequate space

between the window frame and the material for sealant. Refer to the illustration that

corresponds to your finish material.

Note: The sealant details shown are standard recommendations from the sealant industry.

Contact your sealant supplier for recommendations and instructions for these and any

other applications.

B. Check window operation (vent units only) by opening and closing the window.

Note: If the window does not operate correctly, check to make sure it is still plumb, level,

square and that the sides are not bowed. If adjustments are required, remove the foam

interior trim.

A. From the interior, unlock the window and raise the lower sash to

the fully open position.

B. Rotate the screen clips to the open position.

C. Grasp the screen to allow it to pass through the lower sash opening.

D. Position the screen into the window.

Note: The top rail of the screen must be below the bottom rail of

the upper sash.

E. Pull the bottom of the screen in using the screen handle.
