| To meet positive pressure requirements per UBC 7-2 (97) part 1, doors must be installed with Pemko S88 fire-rated smoke and draft control gasketing (category H) on both door jambs and header (See Drawing S). An intumescent seal is also required (category G), as noted below. Refer to gasketing and intumescent manufacturer's installation instructions for frame preparation and application guidelines. |
| Frames must be installed in accordance with the Marshfield DoorSystems™ Care and Handling brochure. Hang doors in accordance with NFPA 80, maintaining a uniform clearance between door and frame. If a threshold is being used, install per manufacturer's installation instructions. Position thresholds prior to adjusting door clearance. Where bottom seals are being used (See Drawing R), seals must be adjusted for proper pressure to maintain acoustic rating, refer to bottom seal manufacturer's installation instructions. |
| When installed per the above instructions Marshfield DoorSystems acoustic positive pressure frame mounted intumescent door meets part 1 of UBC 7-2 (97) Category B considerations and meets ASTM E90-90 and E413. |
