PRODUCT FEATURES
OPERATION
This firebox has been tested and approved
under ANSI Z21.91 for use with any gas
log approved to ANSI Z21.11.2 for indoor
applications and ANSI Z21.97 for outdoor
applications. (Physical size limitations apply.
Refer to minimum firebox requirements sup-
plied with log heater.) It requires no outside
venting or chimney making installation easy
and inexpensive. When used without blower,
heaterinstalledin firebox requires noelectric-
itymaking it idealforemergencybackup heat.
REFRACTORY BRICK LINER

OUTSIDE AIR KIT ACCESSORY
An optional AK4 air kit provides additional
outdoor air to improve burner efficiency and
reduce build-up of condensation in the living
space. Follow instructions included with air kit.
LOCATING FIREBOX
PLANNING
Planwhere you willinstallthe firebox.This will
save time and money later when you install
the firebox. Before installation, consider the
following:
1. Where firebox will be located: Allow for
wall and ceiling clearances (see Installa-

AIR FOR COMBUSTION AND VENTILATION
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the outside
atmosphere have a continuous water
vapor retarder with a rating of one perm
(6 x 10
-11
kg per pa-sec-m
2
) or less 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 floors,
between wall-ceiling joints, between
wall panels, at penetrations for plumb-
ing, 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 10.
If your home does not meet all of the three
criteriaabove, proceedto Determining Fresh-
Air Flow For Firebox Location.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA54 allows two methods for determining
whether the space in which the heater is being
installed is confined or unconfined space. The
standard method defines a confined space as a
space whose volume is less than 50 cubic feet
per1,000Btu per hour (4.8m
3
perkw) of the ag-
gregate input rating of all appliances installed in
that space and an unconfined space as a space
whose volume is not less than 50 cubic feet per
1,000 Btu per hour (4.8 m
3
per kw) of the ag-
gregate input rating of all appliances installed in
that space. Rooms communicating directly with
thespace in which theappliancesare installed*,
through openings not furnished with doors, are
considered a part of the unconfined space.
Where the air infiltration rate of a structure is
known, the Known Air Infiltration Rate Method
may be used. Follow The National Fuel Gas
Code, ANSI Z223.1/NFPA 54 to use this
method to determine if the space is confined
or unconfined.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
Determining if You Have a Confined or
Unconfined Space Using the Standard
Method
Today’s homes are built more energy efficient
than ever. New materials, increased insulation
andnewconstruction methods helpreduceheat
lossinhomes. Homeowners apply weather strip
and caulk around windows and doors to keep
thecoldairout and the warm air in. During heat-
ing months, homeowners want their homes as
airtight as possible.
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning ap-
pliances need fresh air for proper combustion
and ventilation.
Exhaust fans, some fireplaces, clothes dryers
and some fuel-burning appliances draw air from
thehousetooperate.Youmustprovideadequate
fresh air for these appliances. This will ensure
properventingofventedfuel-burningappliances.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel
Gas Code,ANSI Z223.1/NFPA 54,Air for Com-
bustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on Pages 8 through 10 will help
you classify your space and provide adequate
ventilation.
Unusually Tight Construction
The air that leaks around doors and windows
mayprovideenoughfresh airfor combustionand
ventilation. However, in buildings of unusually
tight construction, you must provide additional
fresh air.
WARNING:Thisheatershallnot
beinstalledinaroomorspaceun-
lesstherequiredvolumeofindoor
combustion air is provided by the
method described in the National
FuelGas Code,ANSIZ223.1/NFPA
54, the International Fuel Gas
Code, or applicable local codes.
Read the following instructions
to ensure proper fresh air for this
and otherfuel-burning appliances
in your home.

AIR FOR COMBUSTION AND VENTILATION
Continued
Use this work sheet to determine if you have
a confined or unconfined space.
Space: Includes the room in which you will
install heater plus any adjoining rooms with
doorless passageways or ventilation grills
between the rooms.
1. Determine the volume of the space (length
x width x height).
Lengthx Widthx Height=__________cu. ft.
(volume of space)
Example :Space size 22 ft. (length) x 18 ft.
(width) x 8 ft. (ceiling height) = 3,168 cu. ft.
(volume of space)
If additional ventilation to adjoining room
is supplied with grills or openings, add the
volume of these rooms to the total volume
of the space.
2. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example :3,168 cu. ft. (volume of space) x 20
=63,360(maximumBtu/Hrspacecansupport)
3. Add the Btu/Hr of all fuel burning appliances
in the space.
Vent-free fireplace _________Btu/Hr
Gas water heater* _________Btu/Hr
Gas furnace _________Btu/Hr
Vented gas heater _________Btu/Hr
Gas fireplace logs _________Btu/Hr
Other gas appliances*+ _________ Btu/Hr
Total = _________Btu/Hr
* Do not include direct-vent gas appliances.
Direct-vent draws combustion air from the
outdoors and vents to the outdoors.
Example:
Gas water heater _________Btu/Hr
Vent-free fireplace + _________Btu/Hr
Total = _________Btu/Hr
4. Compare the maximum Btu/Hr the space
can support with the actual amount of Btu/
Hr used.
_______ Btu/Hr (maximum the space can
support)
_______ Btu/Hr (actual amount of Btu/Hr
used)
Example :63,360 Btu/Hr (maximum the
space can support)
79,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the example is a confined space
because the actual Btu/Hr used is more than the
maximum Btu/Hr the space can support. You
must provide additional fresh air. Your options
are as follows:
A. Rework worksheet, adding the space of an
adjoiningroom.Iftheextraspaceprovidesan
unconfined space, remove door to adjoining
room or addventilation grillsbetween rooms.
See Ventilation Air From Inside Building.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, Page 9.
C. Install a lower Btu/Hr fireplace, if lower Btu/
Hr size makes room unconfined.
If the actual Btu/Hr used is less than the
maximum Btu/Hr the space can support, the
space is an unconfined space. You will need
no additional fresh air ventilation.

WARNING: If the area in
which the heater may be oper-
ateddoesnot meet the required
volume for indoor combustion
air, combustion and ventilation
air shall be provided by one of
the methods described in the
National Fuel Gas Code, ANSI
Z223.1/NFPA54,theInternation-
al Fuel Gas Code, or applicable
local codes.

VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconfined space. When ventilating to an
adjoining unconfined space, you must provide
two permanentopenings: one within 12"of the
ceiling and one within 12" of the floor on the
wall connecting the two spaces (see options 1
and2,Figure4).Youcanalsoremovedoorinto
adjoiningroom(seeoption3, Figure3).Follow
the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, Air for Combustion and Ventilation
for required size of ventilation grills or ducts.
AIR FOR COMBUSTION AND VENTILATION

Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 12" of the ceiling
andonewithin12"ofthe floor. Connect these
items directly to the outdoors or spaces open
to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation for required size
of ventilation grills or ducts.
IMPORTANT:Do not provide openings
for inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated air
entering the attic will activate the power vent.
