WARNING: Drilling, sawing, sanding or machining wood products can expose you to wood dust, a substance know to the state of California to cause cancer.

Avoid inhaling wood dust or use a dust mask or other safeguards for personal protection. For more information, go to www.P65warnings.ca.gov

STEP 1: Check Door Unit

Check width and height.

Measure size of frame (width and height), not brickmould.

Remove cleats and packaging, but keep door fastened closed with transport clip.

DO NOT remove the transport clip until instructed to do so later in Step 7.

STEP 2: Check & Prepare Opening

Is the opening the correct size for the door unit? Check it against the door frame size

now, before installation. The opening should be frame height plus 1/2 inch,

and frame width plus 1/2 inch to 3/4 inch. Fix any problems now.

Are the framing and walls plumb? Use a 6-foot level and check both sides of the

opening, both ways (front to back and right to left). Fix any problems now.

Is the sub oor level and solid? Provide a at, level, clean weight bearing surface

so the sill pan or sill can be properly caulked and sealed to the opening.

Scrape sand or ll as required.

NOTE: If additional oor covering clearance is required, attach the shim board to the

sub oor. Be sure to caulk well under the shim board.

Is the opening square? Check all corners with a framing square.

Double check by comparing diagonal measurements. Fix any problems now.

Check to be sure the framing walls around the opening are in the same plane.

Do this by performing a “string test” for plumb.

String Test for Plumb:

Attach a string diagonally across the opening from the outside, as shown. The string(s)

should gently touch in the center, if not the opening is “out of plumb” by twice that

distance and needs to be corrected. Flip the string over itself to check both planes.

Fix any problems now. NOTE: An “out of plumb” condition is one of the most common

reasons door units leak air and water.

STEP 3: Caulk the Sub Floor

On the sub oor at opening, place 3 very large beads of sealant.

Run beads full width of the opening.

Use only elastomeric or polyurethane sealant.

Use an entire tube when caulking along the sub oor.
