Installing the Vent System in a Chase
A chase is a vertical box-like structure built to enclose the gas
fireplace and/or its vent system. Vertical vent runs on the outside
of a building may be, but are not required to be installed inside a
chase.
CAUTION
Treatment of firestop spacers and construction of
the chase may vary with the type of building. These
instructions are not substitutes for the requirements
of local building codes. Check local building codes to
determine the requirements for these steps. Improper
installation of the fireplace can cause serious injury or
death from fire, burns, explosions, or carbon monoxide
poisoning.
NOTICE:
Build the chase large enough to accommodate
the minimum clearance of combustible materials (including
insulation) to the vent system. When installing the vent system
in a chase, insulate the chase as you would the outside walls of
your home. This is especially important in cold climates. Upon
completion of chase framing, install the vent system by following
the instructions in this manual.
