Final Door Install (continued)
41. HAND CHAIN KEEPER
The emergency hand chain for this fire door can be locked.
• Instruct door users to wrap hand chain, as shown in Figure 46.
42. GUIDE SEAL INSTALLATION
NOTE: A Guide Bottom Seal is a UL requirement for each fire door (Model
800FR) with an unlevel floor to keep fire from passing thru the gap under the
guide mounted off the floor. The Bottom Seal is not optional and must be
installed, when required, to fill the gap.
Guide Angle Assemblies normally rest on the floor, but if one guide assembly
is installed above the floor because the floor is not level, then the gap
under the guide must be closed by a sheet of metal (Bottom Seal), as shown
Figure 46
in Figure 47. The sheet metal must be at least 24 gauge steel. It must be
sandwiched between the Guide Angles and bent, as shown below.
NOTE: If door is equipped with slide bolts, notch Bottom Seal, as required for
slide bolt to project through.
