Important Information and Disclaimers

Fire Rated Frames
Fire-labelled frames will be provided for those openings requiring fire protection ratings, as determined and scheduled by the architect. Such products have been tested in strict conformance with CAN4-S104, ASTM E152 or NFPA 252 as listed by a nationally recognized agency having a factory inspection service, in conjunction with the Canadian Steel Door Manufacturers Association, and will be constructed as detailed in the follow–up service procedures.
Frames will be blanked, reinforced, drilled and tapped for mortised template hardware. Mortised cut-outs will be protected with steel guard boxes (may be omitted on drywall applications). Frames will be reinforced, where required, for surface-mounted hardware. Drilling and tapping are to be done by others in the field, at the time of installation. Frames will be prepared for single stud rubber door silencers, three (3) per single door openings.
Unless specified otherwise the location of hinges, strikes and closer reinforcing will be All Steel Doors 2000 standard locations.
All frames should be thoroughly inspected upon receipt and all discrepancies, deficiencies and/or damages must be reported in writing to All Steel Doors 2000 within 3 days of receipt of shipment. All shipments are FOB All Steel Doors 2000. All damages incurred during shipment is to be claimed by the distributor directly from the freight carrier. Frames must be removed from any wrapping or covering and be stored in a protected location in an upright position, on wood sills or planks.
All frames must be set plumb, square and level at the correct elevation. Fire-labelled frames must be installed in accordance with NFPA 80, most current edition.
