GEROUS. IMPROPER INSTALLATION OR
USE OF THIS HEATER CAN CAUSE SERIOUS INJURY OR DEATH FROM FIRE,
BURNS, EXPLOSION OR CARBON MONOXIDE POISONING.
Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to the
flu with headaches, dizziness and/or nausea.
If you have these signs, obtain fresh air immediately. Have the Unvented Gas Heater
serviced as it may not be operating correctly.
• Due to high temperatures, the firebox should
be located out of traffic and away from furniture
and draperies.
• Children and adults should be alerted to the
hazard of high surface temperature and should
stay away to avoid burns or clothing ignition.
• Young children should be carefully supervised when they are in the same room with the
heater.
• Do not place clothing or other flammable
material on or near the heater.
• Any safety screen or guard removed for
servicing the firebox must be replaced and/or
closed prior to operating the heater.
• Installation and repair should be done by a
qualified service person. The heater should be
inspected before use and at least annually by
a professional service person. More frequent
cleaning may be required due to excessive lint
from carpeting, bedding material, etc. It is
important that control compartments, burners
and circulating air passageways of the heater
be kept clean.
• Allow the heater to cool before servicing.
Always shut off any electricity or gas to the
heater while performing service work.
• Do not install the firebox in a sleeping room
or bathroom.
• The appliance and its individual shut-off valve
must be disconnected from the gas supply
piping system while performing any tests of the
gas supply piping system at pressures in excess of ¹⁄₂ psig.
• The heater must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure testing of the gas supply piping system at test
pressures equal to or less than ¹⁄₂ psig.
• Keep heater area clear and free from combustible materials, gasoline and other flammable vapors and liquids.
• Do not use this heater if any part has been
under water. Immediately call a qualified service technician to inspect the heater and to
replace any part of the control system and any
gas control which has been under water.
• Ensure that the heater is clean when operating. Excessive dust accumulation on the burner
and logs will increase the amount of carbon
monoxide formation and could lead to carbon
monoxide poisoning and death.
CODES
Adhere to all local codes or in their absence the
latest edition of The National Fuel Gas Code
ANSI Z223.1 or NFPA54 which can be obtained
from The American National Standards Institute, Inc. (1430 Broadway, New York, NY,
10018) or National Fire Protection Association,
Inc. (Batterymarch Park, Quincy, MA, 02269).
COMBUSTION AND VENTILATION AIR
Heaters installed in these appliances shall not
be installed in a confined space. Heaters
installed in these appliances may be located
in unusually tight construction provided the
space is unconfined, or if confined, is provided with two permanent openings communicating directly with an additional room(s)
of sufficient volume so that the combined
volume of all connected spaces meets the
criteria for an unconfined space, (National
Fuel Gas Code ANSI Z223.1 1992, Section
5.3). Generally 50 ft3 per 1,000 BTU input of
all operating appliances in the space.
The National Fuel Gas Code defines a confined
space as a space whose volume is less than
50 ft3 per 1,000 BTU/Hr (4.8 m3 per 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 ft
per 1,000 BTU/Hr (4.8 m3 per kw) of the aggregate 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 unconfined space.
Unusually tight construction is defined as construction where:
a. wall and ceilings exposed to the outside
atmosphere have a continuous water vapor
retarder with a rating or one perm or less with
openings gasketed or sealed, and
b. weather stripping has been added on operable 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 wallceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines,
and at other openings.
Use the following equations to determine if
you have a confined or unconfined space.
1.Determine the volume of space — ft
Length x Width x Height = _____ ft
(Include adjoining rooms with doorless passageways or ventilation grills between
rooms.)
Example: 24' (L) x 16' (W) x 8' (H) = 3072
3
ft
2.Divide the volume of space by 50 ft3 to
determine the maximum BTU/Hr the space
can support.
______ (volume of space – ft
(Maximum BTU/Hr the space can support)
Example: 3072 ft
3
/ 50 ft3 = 61.44
or 61,440 BTU/Hr the space can support.
3.Add the BTU/Hr of all the fuel burning appli-
ances in the space.
Vent-Free heater _______ BTU/Hr
Gas appliance #1* _______ BTU/Hr
Gas appliance #2 + _______ BTU/Hr
Total = _______ BTU/Hr
Example:
Vent-free heater 26,000 BTU/Hr
Gas appliance #1 40,000 BTU/Hr
(water heater)
Total = 66,000 BTU/Hr
3
* Do not include direct-vent gas appliances.
Direct-vent is sealed combustion and draws
combustion air from the outdoors.
4. Compare the maximum BTU/Hr the space
can support with the actual amount of BTU/
Hr used.
_________ BTU/Hr
(max. the space can support)
_________ BTU/Hr
(actual amount of BTU/Hr used)
Example:
61,440 BTU/Hr
(max. the space can support)
66,000 BTU/Hr
(actual amount of BTU/Hr used)
The space in the above 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.

WARNING: IF THE AREA IN WHICH THE
HEATER MAY BE OPERATED IS SMALLER
THAN THAT DEFINED AS AN UNCONFINED SPACE, PROVIDE ADEQUATE
COMBUSTION AND VENTILATION AIR BY
ONE OF THE METHODS DESCRIBED IN
THE NATIONAL FUEL GAS CODE, ANSI
Z223.1 1992, SECTION 5.3 OR APPLICABLE LOCAL CODES.
Your options are:
a. Rework equations adding the space of ad-
joining room(s). If the extra volume provides
an unconfined space, then remove door or
add ventilation grills between rooms. Refer
to National Fuel Gas Code, ANSI Z223.1
1992, Section 5.3.
b. Vent room directly to the outdoors. Refer to
National Fuel Gas Code, ANSI Z223.1 1992,
Section 5.3.
c. Install a lower BTU/Hr heater, such as a
21,000 BTU/Hr, to make the area an unconfined space.
If the actual BTU/Hr used is less than the
maximum BTU/Hr the space can support, then
the space is an unconfined space. You will need
no additional fresh air ventilation for an unconfined space.
• Never obstruct the front opening of the unvented firebox or restrict the flow of combustion and ventilation air.
• Minimize modifications to existing construction. See
Figure 1
for location suggestions.
WARNING: MAINTAIN MINIMUM
CLEARANCES.
Do not install in the vicinity where gasoline or
other flammable liquids may be stored. The
unvented firebox must be kept clear and free
from these combustible materials.
CAUTION: HEATERS CREATE WARM AIR CURRENTS. THESE CURRENTS MOVE HEAT TO
WALL SURFACES NEXT TO HEATER. INSTALLING HEATER NEXT TO VINYL OR CLOTH WALL
COVERINGS OR OPERATING HEATER WHERE
IMPURITIES IN THE AIR (SUCH AS TOBACCO
SMOKE) EXISTS, MAY DISCOLOR WALLS.
WARNING: DO NOT ALLOW FANS TO
BLOW DIRECTLY INTO THE FIREPLACE.
AVOID ANY DRAFTS THAT ALTER
BURNER FLAME PATTERNS.
WARNING: DO NOT USE A BLOWER INSERT, HEAT EXCHANGER INSERT OR
OTHER ACCESSORY NOT APPROVED
FOR USE WITH THIS FIREPLACE.

If your mantel profile is unsafe, you may either:
• Raise the mantel to an acceptable height, or
• Remove the mantel.
Floor clearance: These fireplaces may sit
directly on a combustible surface.
ASSEMBLY STEPS
Note: Illustrations shown in this manual re-
flect “typical” installations with nominal dimensions and are for design and framing
reference only. Actual installations may vary
due to individual design preferences. However, always maintain minimum clearances to
combustible materials and do not violate any
specific installation requirements. Refer to the
Framing Specifications Figures on page 8.
Note: The following steps represent the normal sequence of installation. Each installation
is unique, however, and might require a different sequence.
Step 1. Position firebox prior to framing or
into prepared framing.
Step 2. Field wire main power supply to circulating models for fan kit. (Electrical connections should only be performed by an experienced, licensed/certified tradesman.)
Step 3. Plumb gas line. (Gas connections
should only be performed by an experienced,
licensed/certified tradesman.)
Step 4. Install decorative type unvented room
heater per the instructions provided with the
unvented room heater.
Step 5. Complete finish wall material, surround and optional hearth extension to your
individual taste.
INSTALLATION
Gas Line Installation
CAUTION: PLUMBING CONNECTIONS SHOULD
ONLY BE PERFORMED BY A QUALIFIED, LICENSED PLUMBER. MAIN GAS SUPPLY MUST
BE OFF WHEN PLUMBING GAS LINE TO FIREPLACE OR PERFORMING SERVICE.
Consult all local codes.
It is recommended that the ¹⁄₂" gas line enter
the side of the firebox. Connect the gas line
before the firebox is enclosed in the finished
wall. The gas knockout is determined by an
indentation located at the bottom and slightly
off center in the side refractories. THE KNOCK-
OUT IS ALWAYS REMOVED FROM INSIDE
THE FIREBOX. If removal is attempted from
the outer wrapper, side-refractory damage
may occur. With a medium-sized hammer,
lightly tap the surface of the indentation. The
refractory material is very thin in this area and
is easily removed. Once a small hole has been
made, continue tapping until you have reached
sufficient diameter for the gas line to fit
through. The entire knockout does not have
to be removed.
Install only a ¹⁄₂" (1 ¹⁄₂" max.) inside diameter
approved gas line through the firebox wall for
connection to the unvented room heater inside
the firebox.
Ensure that a sediment trap is installed in the
existing gas line, if not, install a sediment trap
upstream of the heater to prevent moisture and
contaminants from passing through trap to the
heater controls and burners. Failure to do so
could prevent the heater from operating reliably.
An external regulator must be used on all propane (L.P.G.) heaters, in addition to the regulator fitted to the heater, to reduce the supply tank
pressure to 13" w.c. (maximum). Any copper
tubing used to supply propane (L.P.G.) from
the tank must be internally tinned.
IMPORTANT: HOLD HEATER REGULATOR
WITH A WRENCH TO PREVENT MOVEMENT
WHEN CONNECTING TO INLET PIPING.
Check Gas Type: The gas supply must be the
same as stated on the heater’s rating plate. If
the gas supply is different, DO NOT INSTALL
the heater. Contact your dealer for the correct
model.
WARNING: CONNECTING DIRECTLY TO
AN UNREGULATED PROPANE (L.P.G.)
TANK CAN CAUSE AN EXPLOSION.
IMPORTANT: RE-PACK INSULATION MATERIAL IN SQUARE HOLE AROUND GAS LINE,
INTERIOR AND EXTERIOR, TO SEAL.
Consult installation and operating instructions
for the model of unvented room heater to be
installed.
Checking Gas Connections: Test all gas joints
from the gas meter to the gas heater regulator
for leaks using soap and water solution after
completing connection. DO NOT USE AN OPEN
FLAME.

Firebox Framing
UVF-500 SPECIFICATIONS
Construct firebox framing following
through 8
and the chart on page 8 for your
Figures 6
specific installation requirements. Refer to
Figures 4 and 5
on pages 6 and 7 for firebox
dimensions.
The firebox may be installed directly on a combustible floor or raised on a platform of an
appropriate height. Do not place firebox on
carpeting, vinyl or other soft floor coverings. It
may, however, be placed on flat wood, plywood, particle board, metal or other hard surfaces which extend the full width and depth of
the enclosure. Be sure firebox rests on a solid
continuous floor or platform with appropriate
framing for support and so that no cold air can
enter room from under the firebox.
The firebox may be positioned and then the
framing built around it, or the framing may be
constructed and the firebox positioned into the
opening.
Usually, no special floor support is needed for
the firebox, however, to be certain:
1. Estimate the total weight of the firebox
system and surround materials such as marble,
brick, stone, etc., to be installed.
2. Measure the square footage of the floor
space to be occupied by the system and surrounds.

FIREBOX FINISHES
ACCESSORIES AND COMPONENTS
There are a wide variety of “finished looks” for
your built-in unvented firebox from formal wall
decor with elaborate mantels to rustic wood
paneling or warm brick facings.
Only noncombustible materials like marble,
stone, tile, brick, etc. may overlap the black
front facing but be sure not to block the upper
or lower grilles. Seal all joints between the black
facing and wall surrounds to prevent air intrusion. Use noncombustible caulking material
only to seal the black metal facing to the surround material on the finished wall.
REPLACEMENT PARTS
An exploded view of the firebox with numbered parts and a replacement parts list can be
found on page 11. Normally, all parts should
be ordered through your distributor or dealer.

time of order.
