burns or clothing ignition. Fire-
box will remain hot for a time
after shutdown. Allow surfaces
to cool before touching.
Carefully supervise young children when they are in the room
with rebox.
Keep the replace area clear and
free from combustible materials,
gasoline, and other ammable
vapors and liquids.
You must operate this replace
with the provided fireplace
screen and hood in place. Make
sure these parts are in place
and screens are closed before
running installed gas log heater.
Replace hood with INNOVATIVE
HEARTH PRODUCTS model

PRODUCT FEATURES
OPERATION
This rebox is designed for use with approved
ANS Z21.11.2 decorative type unvented room
appliances. (Physical size limitations apply.
Refer to minimum rebox requirements supplied with log appliance.) The maximum size
log this rebox will accept is: width of 32",
depth of 19" and a height of 17".
This rebox requires no outside venting or
chimney making installation easy and inex-
pensive. When used without the blower, the
rebox requires no electricity making it ideal
for emergency backup heat.
State of Massachusetts: The installation
must be made by a licensed plumber or
gas tter in the Commonwealth of Massachusetts.
Sellers of unvented propane or natural
gas-red supplemental room appliances
shall provide to each purchaser a copy of
527 CMR 30 upon sale of the unit.
Vent-free gas products are prohibited for
bedroom and bathroom installation in the
Commonwealth of Massachusetts.
NOTICE: The rebox identication label (including model number, serial number, clearances,
etc.) is located directly above the
brick liner and under the heat
shield. See Figure 20, page 16.
BLOWER ACCESSORY
The firebox will accept the GA3500A accessory. The variable blower allows you to
select the fan speed you desire. The blower
circulates heated air from the rebox into the
room. Use of blower is optional.
BRICK LINER
This rebox features a concrete brick liner. As
with all concrete liners, this liner may develop
slight cracks when exposed to heat. These
cracks will not affect the performance of the
rebox or vent-free gas logs.

PLANNING
Plan where you will install the rebox. This will
save time and money later when you install
the rebox. Before installation, consider the
following:
1. Where the rebox will be located. Allow for
wall and ceiling clearances (see Installa-
tion Clearances, page 9).
2.
Everything needed to complete installation.
3. This model CANNOT be installed in a
bedroom or bathroom.
4. Proper air for combustion and ventilation.
5. Consider a location where heat output
would not be affected by drafts, air condition ducts, windows or doors.
6. A location that minimizes modications
on existing framing will make installation
easier.
Projected installations can extend any
distance into the room. A projection may
be ideal as a partition between two oth-
LOCATING FIREBOX
erwise common areas when added to an
existing, nished wall (see Figure 2).
Internal wall installation provides a
discreet viewing option between two
adjacent rooms or within an added wall
to subdivide an oversize room.

AIR FOR COMBUSTION AND VENTILATION
WARNING: This appliance
shall not be installed in a room
or space unless the required
volume of indoor combustion
air is provided by the method
described in the National Fuel
Gas Code, ANSI Z223.1/NFPA 54,
the International Fuel Gas Code,
or applicable local codes. Read
the following instructions to insure proper fresh air for this and
other fuel-burning appliances in
your home.
Today’s homes are built more energy efcient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors
to keep the cold air out and the warm air in.
During heating months, home owners want
their homes as airtight as possible.
While it is good to make your home energy
efcient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning appliances need fresh air for proper combustion
and ventilation.
Exhaust fans, reboxes, clothes dryers and fuel
burning appliances draw air from the house to
operate. You must provide adequate fresh air
for these appliances. This will insure proper
venting of vented fuel-burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
Fuel Gas Code ANS Z223.1/NFPA 54,Air for
Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 6 through 8 will help
you classify your space and provide adequate
ventilation.
Unusually Tight Construction
The air that leaks around doors and windows
may provide enough fresh air for combustion
and ventilation. However, in buildings of unusually tight construction, you must provide
additional fresh air.
Unusually tight construction is dened as
construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of one
perm (6 x 10
with openings gasketed or sealed and
b. weather stripping has been added on
openable windows and doors and
c. caulking or sealants are applied to
areas such as joints around window
and door frames, between sole plates
and oors, between wall-ceiling joints,
between wall panels, at penetrations
for plumbing, electrical and gas lines
and at other openings.
If your home meets all of the three criteria
above, you must provide additional fresh
air. See Ventilation Air From Outdoors,
page 8.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow for Firebox Location,
page 7.
Conned and Unconned Space
The National Fuel Gas Code ANS Z223.1/
NFPA 54 denes a conned space as a space
whose volume is less than 50 cubic feet per
1,000 Btu/hr (4.8 m3 per kw) of the aggregate
input rating of all appliances installed in that
space and an unconned space as a space
whose volume is not less than 50 cubic feet
per 1,000 Btu/hr (4.8 m3 per kw) of the ag-
gregate input rating of all appliances installed
in that space. Rooms communicating directly
with the space in which the appliances are
installed*, through openings not furnished
with doors, are considered a part of the unconned space.
This appliance shall not be installed in a
conned space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
