D. Install Ceiling Firestops
CAUTION! Risk of Fire! Ceiling restops must be used
whenever the chimney penetrates a ceiling/oor.
• Chase construction requires ceiling restops at each oor
or every 10 ft (3.05 m) of clear space.
• The ceiling restop slows spread of re and reduces cold
air inltration.
WARNING! Risk of Fire! DO NOT seal area between
restop opening and chimney pipe except where they
enter the attic or leave the warm-air envelope of the
home (use 600° F sealant).
