Innovator Door Installation and Service Instruction P/N 0425683F Heat the Gasket Make sure the door is closed. Beginning at the top of the gap, use a heat gun or electric hair dryer (1500-1600 watt) to heat the gasket with a constant up and down motion. IMPORTANT: If a gap runs the entire length of the door, heat the area 4 in. (100 mm) above and 8 in. (200 mm) below the top-most point where the gap starts and work in 12 in. (300 mm) increments.
P/N 0425683F ® As shown in Figure 15, this can also be accomplished by pushing the magnet across the gap from the outside with a pencil or other non-heat conducting material. Use a soft cloth or paper towels, and a mild soap and water solution to thoroughly clean the gasket. Dry the gasket completely with a fresh cloth or paper towels before closing the door on a clean door frame. DOOR HANDLE REPLACEMENT Figure 15.
