Install The Ceiling Firestops - Quadra-Fire EPA Certified Woodburning Fireplace 7100FP-GD-B Owner's Manual

7100FP EPA Woodburning Fireplace
WARNING
Fire Risk
• The flex hose must never be
compressed or deformed!
Restricting the airflow inside the flex pipe
may increase flue pipe temperatures causing
a chase fire.
Figure 24.1 Installing Flex Pipe
F. Install the Ceiling Firestops
• Mark and cut an opening in the ceiling for the ceiling
firestop being used. See Figure 24.2.
• 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 25.1 and 25.2 on page 25.
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 24.2). When the attic insulation shield is used
the ceiling firestop may be above or below the joist of an
insulated ceiling.
