4. Assemble Chimney Sections
Attach either a straight chimney section or an offset to the top of the fireplace (depending on your installation requirement). Chimney sections are locked together by pushing downward until the top section meets the stop bead on the lower section.
The inner flue is placed to the inside of the flue section below it. The outer casing is placed outside the outer casing of the chimney section below it. See Figure 10.
WARNING!
Carefully follow the instructions for assembly of the pipe and other parts needed to install this fireplace system. Failure to do so may result in a fire, especially if combustibles are too close to the fireplace or chimney and air spaces are blocked, preventing the free movement of cool- ing air.
5. Install Firestop Spacers
Mark and cut out an opening in the ceiling for the firestop spacer being utilized
Install the firestop spacer.
These firestop spacers are designed to provide the minimum 2 in. 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 insulation from falling into the required 2 in. air space around the chimney. See Figure 11.
CAUTION:
Firestop spacers must be used whenever the chimney penetrates a ceiling/floor area.
