INSTALLATION
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
Figure 25
for
minimum framing dimensions.
CAUTION
Measure fireplace dimensions and verify framing methods,
and wall covering details before framing construction begins.

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:
Treatment of ceiling firestops 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. Therefore, you MUST check local building
codes to determine the requirements to these steps.
A chase should be constructed in the manner of all outside walls
of the home to prevent cold air drafting problems. The chase
should not break the outside building envelope in any manner.
Walls, ceiling, base plate and cantilever floor of the chase should
be insulated. Vapor and air infiltration barriers should be installed in
the chase as per regional codes 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.
FRAMING AND FINISHING
1. Choose fireplace location. See page 18.
2. Frame in fireplace with a header across the top.
3. Retrieve the four framing brackets from hardware pack and
hand bend them into a V shape as shown in
Figure 26.
4. Attach framing brackets to the fireplace with included #10 X
1/2-inch screws. Brackets can be either flush to the fireplace
or set back 1/2-inch, according to the desired finishing
method.
See Figures 26, 31 and 32.
5.
Secure fireplace to framing with nailing flanges.
See Figure 27.
