4. Install Firestops
For Horizontal Runs -
Firestops are
REQUIRED
on both sides of a combustible wall through which
the vent passes.
NOTE
Model DVK-01TRD or SLK-01TRD do not need an
exterior firestop on an exterior combustible wall.
To install firestops for horizontal runs that pass
through either interior or exterior walls:
Cut a 12-inch by 12-inch (305 mm X 305 mm)
hole through the wall for D-series or a 10-inch by
10-inch (254 mm X 254 mm) hole for SL-D-
series pipe. The center of the hole is one (1) inch
(25.4 mm) above the center of the horizontal vent
pipe.
