SAFETY
INFORMATION
IMPORTANT: Read this owner’s
manual carefully and completely
before trying to assemble, oper-
ate, or service this firebox. Im-
properuseofthisfireboxcancause
seriousinjuryordeathfromburns,
fire,explosion,electricalshock,or
carbon monoxide poisoning.
WARNINGS
CAUTION: Carefully review
theinstructionssuppliedwiththe
decorative type unvented room
heater for the minimum fireplace
size requirement. Do not install
the appliance in this firebox, un-
less this firebox meets the mini-
mumdimensionsrequiredforthe
installation.
WARNING: Any change to
this firebox or its controls can
be dangerous.
6. Do not allow fans to blow directly into
the firebox. Avoid any drafts that alter
burner flame patterns. Ceiling fans can
create drafts that alter burner flame
patterns. Altered burner patterns can
cause sooting.
7. Donotuseablowerinsert,heatexchanger
insert or other accessory not approved for
use with this heater. Do not use blower
accessory with Model RUV32. Use only
the provided hood or GA6096 polished
brass hood accessory (see Accessory on
page 11).
8. Vent-free gas log heaters installed in
these fireboxes require fresh air venti-
lation to run properly. See Air for Com-
bustion and Ventilation, pages 4
through 6.
9. Do not run firebox
• where flammable liquids or vapors
are used or stored
• under dusty conditions
10. Do not use this firebox to cook food or
burn paper or other objects.
11. Never place any objects in the firebox
or on logs.
12. Firebox front and screen becomes very
hot when running firebox. Keep chil-
dren and adults away from hot surfaces
toavoid burns orclothing ignition. Fire-
box will remain hot for a time after
shut-down. Allow surfaces to cool be-
fore touching.
13. Carefully supervise young children
when they are in the room with fire-
box.
14. Turn firebox off and let cool before
servicing. Only a qualified service per-
son should service and repair firebox.
15. Operating vent-free log sets in a fire-
box above elevations of 4,500 feet
could cause pilot outage.
16. Do not use the firebox if it has been
under water due to the shock hazard
that could result with the blower acces-
sary (if installed) in place.

will save time and money later when you
install the firebox. Before installation, con-
sider the following:
1. Where the firebox will be located. Al-
lowforwall and ceiling clearances (see
Installation Clearances, page 7).
2. Everything needed to complete instal-
lation.
3. These models CANNOT be installed
in a bedroom or bathroom.
4. Proper air for combustion and ventila-
tion (see below).

foradequatecombustionandven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
buildings of unusually tight construction,
you must provide additional fresh air.
Unusually tight construction is de-
fined as construction where:
a. walls and ceilings exposed to the
outside atmosphere have a con-
tinuous water vapor retarder with
a rating of one perm (6x10-11 kg
per pa-sec-m2) or less with open-
ings 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, be-
tween sole plates and floors,be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tionsforplumbing,electrical,and
gas lines, and at other openings.
If your home meets all of the three
criteria above, you must provide ad-
ditional fresh air. See Ventilation Air
From Outdoors, page 6.
If your home does not meet all of the
three criteria above, proceed to Deter-
mining Fresh-Air Flow For Firebox
Location , page 5.
Confined Space and Unconfined
Space
TheNationalFuelGasCode(ANSZ2123.1,
1992 Section 5.3) defines a confined space
as a space whose volume is less than 50
cubicfeetper1,000Btuperhour(4.8m3per
kw) of the aggregate 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 m3per kw) of the aggregate
inputratingofallappliancesinstalledinthat
space.Rooms communicatingdirectly with
the space in which the appliances are in-
stalled*, through openings not furnished
with doors, are considered a part of the
unconfined space.
This heater shall not be installed in a con-
fined space or unusually tight construction
unlessprovisions are providedfor adequate
combustion and ventilation air.

OWNER’S MANUAL
DETERMINING FRESH-AIR FLOW FOR FIREBOX LOCATION
Determining if You Have a Confined or Unconfined Space
Use this work sheet to determine if you have a confined or unconfined space.
Space:Includes the room in which you will install firebox 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).
Length x Width x Height = _________________cu. ft. (volume of space)
Example : Space size22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) = 3168 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. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.
__________ (volume of space) ÷50 cu. ft. = (Maximum Btu/Hr the space can support)
Example: 3168 cu. ft. (volume of space) ÷50 cu. ft. = 63.3 or 63,300 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Gas water heater* _____________________ Btu/Hr
Gas furnace _____________________ Btu/Hr
Vented gas heater _____________________ Btu/Hr
Gas firebox 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.
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: 63,300 Btu/Hr (maximum the space can support)
79,000 Btu/Hr (actual amount of Btu/Hr used)
ThespaceintheaboveexampleisaconfinedspacebecausetheactualBtu/HrusedismorethanthemaximumBtu/Hrthespacecansupport.
You must provide additional fresh air. Your options are as follows:
A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air from Inside Building, page 6.
B. Vent room directly to the outdoors. See Ventilation Air from Outdoors, page 6.
C. Install a lower Btu/Hr firebox, 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.

COMBUSTION
AND VENTILATION

WARNING: If the area in which the firebox and gas log heater may be operated is smaller than that defined as
an unconfined space or if the building is of unusually tight construction, provide adequate combustion and
ventilation air by one of the methods described in the National Fuel Gas Code, ANS Z223.1, 1992, Section 5.3 or
applicable local codes.
