Raised Hearth Extension
A hearth extension may be used, but is not required for
these reboxes.
A combustible hearth extension can be constructed ush
with, but not above the rebox oor. On ush installa-
tions, carpet or vinyl is not allowed within 14 inches of
the rebox opening. See Figure 3.6.
Figure 3.6 Raised Hearth Extension
Firebox framing can be built before or after the appliance is
set in place. Construct rebox framing following Figure 3.3
for your specic installation requirements. Refer to Figure
3.1 on page 6 for rebox dimensions.
The rebox may be installed directly on a combustible
oor or raised on a platform. When the rebox is installed
directly on carpeting, tile, or other combustible material,
other than wood ooring, the rebox shall be installed on a
metal or wood panel extending the full width and depth of
the enclosure.
WARNING! Risk of Fire! DO NOT ll spaces around re-
box with insulation or other materials. This could cause a
re.
WARNING! Risk of Fire! The rebox must be installed
giving full consideration to the clearance and height re-
quirements identied in this manual.
E. Constructing the Appliance Chase
A chase is a vertical box-like structure built to enclose the
rebox.
NOTICE: 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.
Chases 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 oor of the chase
should be insulated. Vapor and air inltration barriers should
be installed in the chase as per regional codes for the rest
of the home. Additionally, in regions where cold air inltra-
tion 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, gas line holes and other open-
ings should be caulked with caulk with a minimum of 300ºF
continuous exposure rating or stued with unfaced insulation.
If the rebox is being installed on a cement surface, a layer of
plywood may be placed underneath to prevent conducting cold
up into the room.
NOTICE: Install rebox on hard metal or wood surfaces
extending full width and depth. DO NOT install directly on
carpeting, vinyl, tile or any combustible material other than
wood.
WARNING! Risk of Fire! Maintain specied air space
clearances to rebox:
• Insulation and other materials must be secured to prevent
accidental contact.
• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and making
contact with rebox.
• Failure to maintain airspace may cause overheating and
a re.

A. Securing and Leveling the Firebox
WARNING! Risk of Fire! Prevent contact with:
• Sagging or loose insulation
• Insulation backing or plastic
• Framing and other combustible materials
Block openings into the chase to prevent entry of blown-
in insulation. Make sure insulation and other materials
are secured.
DO NOT notch the framing around the rebox standos.
Failure to maintain air space clearance could cause
overheating and re.
The diagram shows how to properly position and secure the
rebox. See Figure 4.1. Nailing tabs are provided to secure
the rebox to the framing members.
• Bend out nailing tabs on each side.
• Place the rebox into position.
• Keep nailing tabs ush with the framing.
• Level the rebox from side to side and front to back.
• Shim the rebox as necessary. It is acceptable to use
wood shims underneath the rebox.
• Secure the rebox to the framing by using nails or screws
through the nailing tabs.

B. Moisture Resistance
This outdoor appliance will shed moderate amounts of wa-
ter, but is not waterproof. This appliance must be enclosed
or covered with noncombustible nish material and all joints
sealed to prevent water inltration.
The rebox will not perform as an exterior wall. Moisture
penetration must be considered for construction that plac-
es the appliance in structure walls or on moisture sensitive
surfaces.
When installed on exterior walls: Hearth & Home Tech-
nologies recommends that the chase be constructed out-
side the structure’s weather envelope. Where the platform
meets the wall, use a ashing detail similar to that required
for attached decks. Chase platforms, including hearths
should slope away from the structure at 1/8 in. to 1/4 in. per
foot. The appliance can be shimmed level.
Install on wood, composite or non-combustible at surface,
extending full width and depth of the appliance to prevent
damage.
Water Drainage: The appliance is designed to operate
outdoors experiencing rain and other sources of moisture
that will enter the rebox. The appliance has built-in drain
holes in the base which will allow moisture to pass through
the bottom of the enclosure. When constructing the enclo-
sure, the builder must provide a means of draining water
from under the appliance and out of the structure. This can
be achieved by properly positioned drain holes, slots or
other means to allow water to exit at the lowest grade of
the structure. Choosing the location of the appliance is also
important so that an area that may experience excessive
water ow or standing water is avoided. In some cases a
drain pan is needed to ensure proper drainage. This can
be constructed from a corrosion resistant metal, or suitable
material for outdoor use with a water resistant membrane.
A slope of 1/4” per foot toward the drain ports of the struc-
ture is recommended. A drain pan can also be purchased
(ODGSDP-36) for the 36 inch appliance or the (ODGS-
DP-42) for the 42 inch appliance. For a at horizontal in-
stallation where the bottom of the appliance is sitting on the
hearth, use (ODGSDPFLT-36) OR (ODGSDPFLT-42).
Acceptable method for application of moisture membrane
material shown. See gifures 4.2, 4.3 and 4.4.
The appliance will not perform as an exterior wall. Mois-
ture penetration must be considered for construction that
places the appliance in structure walls or on moisture sen-
sitive surfaces.

Gas Information
• The gap between supply piping and gas access hole may
be caulked with caulk with a minimum of 300ºF continuous
exposure rating or stued with non-combustible, unfaced
insulation to prevent cold air inltration.
• Ensure that gas line does not come in contact with outer
wrap of the rebox. Follow local codes.
• Pipe incoming gas line into rebox.
• Refer to vent-free gas appliance installation instructions
for gas connection and lighting instructions.
WARNING! Risk of Fire or Explosion! Support control
when attaching pipe to prevent bending gas line.
• A small amount of air will be in the gas supply lines.
WARNING! Risk of Fire or Explosion! Gas build-up
during line purge could ignite.
• Purge should be performed by qualified service
technician.
• Ensure adequate ventilation.
• Ensure there are no ignition sources such as sparks or
open ames.
Light the appliance. It will take a short time for air to purge
from lines. When purging is complete the appliance will
light and operate normally.
