F. Install the Ceiling Firestops

Mark and cut an opening in the ceiling for the ceiling firestop being used. See Figure 23.2.

Frame the opening with the same size lumber used in the ceiling joists.

Install the firestop spacer.

These firestop spacers are designed to provide the minimum 2 in. (51 mm) air space required around the chimney. In all situations, the firestop spacers are to be nailed to the ceiling joists from the bottom or fireplace side, EXCEPT when the space above is an insulated ceiling or attic space. In this situation, the firestop spacer must be nailed from the top side to prevent loose insula- tion from falling into the required 2 in. (51 mm) air space around the chimney.

NOTE: See Figures 24.1 and 24.2 on page 24.

CAUTION

Ceiling firestops must be used at ceiling/floor.

Chase construction requires ceiling firestops at each floor or every 10 ft (3.05 m) of clear space.

Use same dimensional lumber as joists.

Ceiling firestop slows spread of fire and reduces cold air infiltration.

Note: The ceiling firestop MUST be nailed to the bottom of the ceiling joists EXCEPT when the space above is uninsulated and the attic insulation shield is not being used (see Figure 23.2). When the attic insulation shield is used the ceiling firestop may be above or below the joist of an insulated ceiling.
