• Under most circumstances we suggest that you have a plumb and level rough opening 1″ wider than the finished outside jamb width and 1/2″ taller than the finished outside jamb height.
• Make sure that the floor is clean and level. If it is not level, you will need to shim the bottom of the jamb to get it level.
• Apply a couple of generous beads of good quality construction adhesive to the floor area on which the jamb is to be installed.
• Place the Jamb into the opening (without door(s) or side lites installed) — usually the back of the brick mold will rest directly against the sheathing on the outside of the house. Check for plumb and level. You must check the threshold along with the outer jamb legs for level — both front to back and left to right.
• Starting at a top outside corner and working your way down, begin to shim the jamb leg to achieve level of the jamb leg that the door(s) hang on. (Make sure that you use an appropriate lever — at least a 72″ level should be used for vertical jamb legs) You should secure the jamb leg to the wall with 3″ dry wall screws or suitable substitute (this should be selected based on wall construction material or other contributing factors). Depending on the diameter of the screw that you use you may need to pre-drill. 80″ doors should be secured in at least <4> locations on either side and 96″ doors should be secured in at least <5> locations on either side. Shim and secure transoms or jamb headers as needed to get door(s) in opening and check for proper operation and adjust jamb, if necessary. For Jamb(s) with side lite(s) we suggest that you anchor the bottom of the side lite jamb (close to the door opening) to the floor with an appropriate fastener.
*** We suggest that jambs for door(s) only be secured with screws right behind permanent door stop (these will be covered by the kerfed weatherstripping). Jambs with door(s) and side lite(s), be secured in side lite opening just behind the permanent stop (these will be covered by the side lite(s) and/or transom(s) Please call for further information, if needed. ***
• After the door(s) is installed and works properly, you may proceed with the installation of the side lite(s) and transom(s). With stop removed, apply a small bead of clear silicon sealant to permanent stop. Next, insert side lite(s) and/or transom(s) and secure with stop and brad nails. Side lites should be installed with the removable stop to the inside.
• After the doors are installed and plumb and level, make and cut the strike plates for the lockset, deadbolt, and flush bolts.
*** We always suggest that all of your door units be installed by a qualified installer. If you or your installer have any questions, please don’t hesitate to call. We have tried to make these instructions as complete as possible, but please understand that every door unit and situation can be different. We will work with our customers to assist them achieve the best possible results. ***
