Installation Instructions for Warnock Hersey and Underwriter's Laboratories Labeled Frames, Doors and Windows for Positive Pressure Applications.
Frames Hollow metal fire door frames are labeled for compliance with UBC 7-2-1997 and UL 10C positive pressure requirements. These frames also meet the requirements of UL 10B, NFPA 252, and ASTM E-152. A door labeled for UBC 7-2-1997 or UL 10C positive pressure compliance must be installed in each of these door frames. See the appropriate door installation instructions. Intumescent seals are not required for hollow metal frames with hollow metal doors to comply with UBC 7-2-1997. If a wood door is being installed in a hollow metal frame, the door must be installed in accordance with the wood door manufacturer’s labeling procedure and installation instructions. Intumescent seals may be required for wood doors. Fire door frames (and approved doors) must be installed with the manufacturer’s instructions (or SDI-105 “Recommended Installation Instructions for Steel Frames” or HMMA 840-99 “Installation and Storage of Metal Doors and Frames”) and in accordance with NFPA 80. 1/2” penetration of gypsum wall board is required at all drywall frames. However, it is permissible to notch the wallboard at mortar boxes and electrical junction boxes to allow for a minimum of 1/4” penetration at hardware preps provided the wallboard penetration elsewhere into the frame remains a minimum of 1/2” deep. Listed hardware is to be used in accordance with NFPA 80. SMOKE AND DRAFT CONTROL: Smoke and draft control openings require the use of "Category H" gasketing that is labeled for compliance to UBC 7-2-1997 part 1 (for fire) and part 2 (for smoke and draft control). See the gasketing manufacturer's installation instructions. Louvers are not permitted in smoke and draft control openings and the installation of a louver in a fire door or fire door frame renders void any "S" that may be indicated on the door or frame label.
Doors Hollow metal fire doors are labeled for compliance with UBC 7-2-1997 and UL 10C positive pressure requirements. These doors also meet the requirements of UL 10B, NFPA 252, and ASTM E-152. Doors must be installed in frames labeled for UBC 7-2-1997 or UL 10C positive pressure compliance, or at the discretion of the Authority Having Jurisdiction, in a frame labeled for compliance with UL 10B, NFPA 252 or ASTM E-152.

Listed hardware is to be used in accordance with NFPA 80. Door clearances must also meet the requirements of NFPA 80. Lite kits must be approved for positive pressure requirements and must be installed in accordance with the lite kit manufacturer’s installation instructions. Listed louvers are permitted in positive pressure fire rated doors (see individual door listings). Doors with unchanneled light or louver cut-outs are intended for use with Anemostat kits utilizing HM-Clips or with those Air Louver kits which are approved for installation without channeling. SMOKE AND DRAFT CONTROL: Smoke and draft control openings require the use of "Category H" gasketing and bottom sweeps that are labeled for compliance to UBC 7-2-1997 part 1 (for fire) and part 2 (for smoke and draft control).
