Installation

Deliver door(s) to building site after plaster or cement is dry. If doors are stored at job site for more than one week, all edges should be sealed.
Handle with clean gloves and do not drag doors across one another or across other surfaces.
Store flat on a level surface in a dry, well-ventilated building. Cover to keep clean, but allow air circulation.
Doors should not be submitted to: abnormal heat, extreme dryness, humid conditions or sudden changes therein. They should be conditioned to average prevailing relative humidity of the locality before hanging.

The utility or structural strength of the door must not be impaired in the fitting of the door, the application of hardware, or cutting and altering the door for lights, louver, panels or any other special details.
For exterior doors, use three hinges on doors 7’0″ in height or less, and four hinges on doors over 7′ in height.
For all interior doors use three hinges, except two hinges may be used for 1 3/8″ doors weighing less than 50 pounds or 6’8″ or less in height. All doors 7’6″ or higher require four hinges. Allow a fitting clearance of 1/16″ on the hinge side and 118″ on the lock side.
Where installed for outward swing with no protection from the elements, doors must be properly protected by flashing or other suitable means.
Before finishing. remove handling marks or effects of exposure to moisture with a thorough, final sanding over all surfaces of the door using a 3/0 or 5/0 sandpaper and clean before applying sealer or finish. Some species of wood contain a chemical (oak particularly) which reacts unfavorably with certain finishes. Where possible, the surface should be tested for such favorable reactions.
Application of a sealer before finishing will usually prevent this difficulty. The full beauty of wood is best emphasized by the use of a satin or semi-gloss finish.
Immediately after fitting, or cutting for closures, weatherstrip and/or threshold, and before hanging any interior or exterior door on the job, the entire door, including the top and bottom edges, must receive an application of a primer and two coats of a good grade of paint, varnish or lacquer.
Adequate drying time must be allowed between coats. For job site finishing, do not use a water-thinned paint unless an oil base prime coat is first applied. Exterior finishes shall be used on the exterior face and all edges of exterior doors.
