Installation Instructions

iv
Preserving Design Pressure Test Ratings
IMPORTANT: Thoroughly read and follow these instructions. Failure to install as
recommended will void any warranty, expressed or implied. Before installation, check building
codes for the area in which the doors are being installed, to ensure proper compliance.
The installation instructions that follow are based on typical frame construction. Specific applications
may differ. The door manufacturer recommends that you consult a qualified installation professional.
The door manufacturer is not responsible for installation.
IMPORTANT: A number of jurisdictions have adopted building code Design Pressure
Requirements (DPR) that require window and door products be installed in the same way they were
installed for laboratory testing. To comply with these requirements, we are pleased to supplement the
installation instructions with the following:
Sealant must be applied in all installations. Additionally, to maintain design pressure ratings,
there must be continuous contact with a generous bead of sealant between the bare
sheathing and the door unit’s nailing fin around the door’s entire perimeter.
The following additional steps must be taken as appropriate to maintain design pressure
ratings.
• Exterior weather resistant barrier (WRB) must be cut and temporarily taped back away
from rough openings.
• When sealant is applied to the rough opening it must be applied directly to the building’s
sheathing and NOT
the weather resistant barrier.
• The nailing fin or brickmould must contact the sealant continuously along the entire
perimeter of the unit and must fully contact exterior face of the wall around the door’s
entire perimeter.
• Exterior weather resistant barrier must be trimmed and reapplied over the nailing fin. It
must be sealed to the fin along the entire perimeter with silicone sealant.
• A shim space is required around the sides and head of the door to allow for structure
movement, seasonal expansion and contraction, and to provide space for insulation.
The shim space for DPR installations cannot exceed 1/4" on all sides (1/2" total for
either width or height). For Non-DPR installation, the shim space may be 1/4" to 3/8"
(1/2" to 3/4" total for either width or height).
Accessories, such as jamb extension, may alter unit width and height. Check rough
opening size vs unit size accordingly.
If a shim space greater than listed above exists on the interior or exterior of the unit, use
solid continuous furring material to fill this space until the maximum shim allowance is
achieved. Doors do not require a shim space at the sill.
• Furring material must be solid, continuous, and run the full height and/or width of the
rough opening. Furring strip depth must be at least equal to the door’s jamb depth.
Furring material must be securely fastened to the rough opening framing.
• Fastening methods must conform to those used to install test units. See the following
page for correct fastener type, application spacing, and additional silicone sealant
requirements.
ADDITIONAL NOTES FOR ALL INSTALLATIONS:
• For any installation that has exposed fasteners, it is recommended to use fasteners made
of 300 series stainless steel. Follow your local codes if they specify a different series of
stainless steel.
• Certain options, accessories, and warranty considerations require the unit be installed
using installation clips. The clip install method has not been tested for design pressure
ratings and should not be used where design pressure ratings must be maintained.
