FINISHING INSTRUCTIONS

TOLERANCES

1. Adequate finish on all door surfaces as detailed below.
2. Proper adjustment of hardware attached or fitted into the doors (including the hardware fasteners) as detailed below.
3. Proper storage and handling as detailed below.

1. Wood is hygroscopic and dimensionally influenced by changes in moisture content caused by changes within its surrounding environment. To assure uniform moisture exposure and dimensional control all surfaces must be finished equally.
2. Doors are not ready for finishing when initially received. Before finishing, remove all handling marks, raised grain, scuffs, burnishes and other undesirable blemishes by block sanding all surfaces in a horizontal position with a 120, 150, 180 grit sandpaper. To avoid cross grain scratches, sand with the grain.
3. All exposed wood surfaces must be sealed including the top and bottom rails with a minimum of 2 coats of a non-water base exterior grade sealer. The finish must be inspected once per year and refinished as often as required to maintain the protective integrity of the finish.
4. Cutouts for hardware in exterior doors must be sealed prior to installation of hardware and exposure to weather.
5. Dark colored finishes should be avoided on all surfaces if the door is exposed to direct sunlight, in order to reduce the chance of warping or face checking.

1. Size tolerance: thickness = 1.6 mm. (1/16") length = 1.6 mm. (1/16") width = 1.6 mm. (1/16")
2. A squareness tolerance of not more than 3 mm. (1/8") difference shall be allowed between the diagonal measurements, taken across the face of the door.
3. Doors which develop warp or twist in excess of 6 mm. (1/4") after hanging will be deemed to be defective unless there is evidence to indicate that the door has been improperly stored, finished, or hung, or has been subject to tension (e.g. by wedging). Warp is measured by placing a straightedge on the concave face and determining the maximum distance from straight edge to door face.
4. Stile, rail, and core show-through (telegraphing) will not be considered a defect unless the face of the door varies from a true plane in excess of 1/100" in any three-inch span.

STORAGE AND HANDLING INSTRUCTIONS

INSTALLATION INSTRUCTIONS

EXCLUSIONS

1. Doors to be stacked on 38 mm. (11/2") blocking with a cover sheet top and bottom to protect the face of the doors from sunlight, dirt, water, and abuse, but allow for air circulation under and around the stack. 3 blocks to be used for doors up to 2134 mm. (7'0") and 4 blocks for larger doors.
2. Doors shall not be subjected to extremes of heat and /or humidity, and the storage building must have these conditions controlled. Relative humidity should not be less than 25%, or more than 55%.
   
   Do not store doors in buildings with excessive moisture from newly poured concrete or new plaster/drywall.
3. Certain species of doors are very susceptible to discoloration from direct sunlight or some forms of artificial light, therefore all doors should be protected from light sources with coversheets and opaque wrapping material.
4. Heating, ventilation and air conditioning systems must be operational and balanced before door installation.
5. Doors must be sealed on the top and bottom rails within 5 days of storage on the jobsite.
6. Doors shall be handled with clean hands or while wearing clean gloves.
7. Doors shall not be dragged across each other or across other surfaces.

1. Doors shall be allowed to become acclimatized to finished building heat and humidity before hanging.
2. Do not impair the utility or the structural strength of the door in the fitting, the application of hardware, or cutting and altering the door for lights, louvers, or other special details. Approximately 24 mm. (1/32") clearance on each side and 24 mm. (1/32") to (1/8") clearance at the top shall be allowed.
3. Pilot holes must be drilled for all screws that act as hardware attachments. All hardware installations must follow the listing specifications as per the directions for an approved fire rated opening.
4. Three hinges shall be installed for doors 2134 mm. (7'0") in height or less. Allow one additional hinge for each additional 305 mm. (12") of door height or portion thereof.
5. Labels on fire doors shall not be removed. Doing so voids the label.
6. Properly protect top and bottom edges of exterior doors and bottom of lite or louver cutouts in exterior doors with flashing to prevent moisture from absorbing into the core. Exterior lip moldings must be used in lite openings in exterior doors.
7. Exterior installations must have a minimum roof overhang of 1 m (39") to protect the door from direct exposure to extreme weather conditions.

1. When concealed closers are used.
2. Edges exposed by lite or louver openings and hardware cutouts which are not double-sealed with an exterior sealer.
3. Openings which have no exterior lip moldings, or where the top and bottom of openings are not sealed with aluminum flashing.
4. A minimum of 1 m. (39") of roof overhang is not provided to protect the door from exposure to extreme weather conditions.
5. Exterior doors that are less than 45 mm. (13/4") thick.

1. Appearances of field-finished doors.
2. Natural variation in the color or texture of wood.
3. Normal wear and tear, including wear-through of the finish, or deterioration for reasons other than material and workmanship of the door itself.
4. Plastic laminate surfaced doors in exterior locations.
5. Appearances of high gloss on doors.
6. Incompatibility of hardware with a particular door construction.
7. Warp on doors less than 13/4" thick which are wider than 3'0" or higher than 7'0".
8. Doors over 7'0" in height hung with three or fewer hinges (pivot hardware included).
9. Doors altered by others (not to include machining for hardware).
10. Doors with different materials on either side.
11. Doors with face grooving into or through crossbands.
12. All claims asserted after the time limitation set forth herein are not covered by this warranty.
