Framing
This fireplace can be elevated off the floor provided that the
fireplace is properly supported by framing materials and the
ceiling clearances are maintained.
Fireplace framing can be built before or after the fireplace is
set in place. Framing should be positioned to accommodate wall
covering and fireplace facing material. The fireplace framing
should be constructed of 2 x 4 lumber. Refer to the figure below
for minimum framing dimensions.
NOTICE: Measure fireplace dimensions; verify both framing
methods and wall covering details before framing construction
begins.
NOTICE: Framing depth dimension C is appropriate for 1/2- inch
drywall or exterior sheathing. Adjust accordingly if 3/4-inch
material is used, or for flush interior wall applications.

Construction of a Fireplace Chase
A chase is a vertical box-like structure built to enclose the gas
fireplace and/or its vent system. In cooler climates the vent
should be enclosed inside the chase.
NOTICE: Requirements for ceiling and wall shield firestops 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 to these steps.
To prevent cold-air draft problems, construct the chase in
the manner of all outside walls. The chase should not break
the home's outside envelope. Insulate the walls, ceiling, base
plate, and cantilever floor of the chase and install vapor and air
infiltration barriers per code for the rest of the home.
Additionally, in regions where cold air infiltration may be an
issue, the inside surfaces may be sheet rocked and taped (or
an equivalent method may be used) to achieve maximum air
tightness.
To further prevent drafts, the wall shield and ceiling firestops
should be caulked with caulk rated for a minimum of 300°F
continuous exposure rating to seal gaps. Gas line holes and other
openings should be caulked or stuffed with unfaced insulation.
If the fireplace is being installed on a cement surface, a layer of
plywood may be placed underneath to prevent conducting cold
up into the room.
