DANGER: Carbon monoxide poisoning may lead to
death.
Carbon Monoxide Poisoning:
Early signs of carbon monoxide poisoning resemble
the flu, with headaches, dizziness, or nausea. If you
have these signs, the heater may not be working
properly. Get fresh air at once! Have heater serviced.
Some people are more affected by carbon monoxide
than others. These include pregnant women, persons
with heart or lung disease or anemia, those under the
influence of alcohol, and those at high altitudes.
Propane/LP Gas:
Propoane/LP gas is odorless.An odor making agent is
added to propane/LP gas. The odor helps you detect
a Propane/LP gas leak. However the odor added to
propane/LP gas may be present even though no odor
exists. Make certain you read and understand all
warnings. Keep this manual for reference. It is your
guide to safe and proper operation of this heater.

PRECAUTIONS:
1. 10,000 BTU may be installed in a bedroom, but not
a bathroom, or any place where a strong wind would
shut down the appliance.
2. This heater needs outside ventilation air to run
properly. The Oxygen Depletion Sensor (ODS) safety
shutoff system shuts down the heater if not enough
fresh air is available. See Fresh Air for Combustion
and Ventilation, page 5.
3. Keep all air openings in heater clear, free of debris
or any blockage. This will insure that enough air for
proper combustion enters the heater.
4. If heater shuts off, do not relight until you provide
fresh, outside air. If heater keeps shutting off, it
requires servicing.
5. Turn off and let cool before servicing. Only a qualified
service person should service and repair heater.
6. Do not run heater:
• Where flammable liquids or vapors are used or stored
• During dusty conditions.
7. Before using furniture polish, wax, carpet cleaner or
similar products, turn heater off. If heated the vapors
from these products may create a white powder
residue within burner box or on adjacent walls or
furniture.
8. Do not use heater if any part has been underwater.
Immediately call a qualified service technician to
inspect the room heater and to replace any part of
the control system and any gas control which has
been underwater.
9. Operating heater above elevations of 4,500 feet
could cause pilot/ODS to shutdown heater.
10. Always run heater with control knob in a locked
position. Never set control knob between locked
positions. Poor combustion and higher levels of
carbon monoxide may result if control knob is left
between locked positions.

b. Whether stripping has been added on operable
windows and doors, and
c. Caulking or sealants are applied to areas such
as joints around windows and door frames,
between wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and gas lines,
and at other openings.
If you home does not meet all of the three criteria
above, see Determing the Type of Heater Location
Space, below.
Confined Space and Unconfined Space
The National Fuel Gas Code, NFPA 54/ ANSI Z223.1
defines a confined space as a space whose volume is
less than 50 cubic feet per 1,000 Btu per hour (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 cubic feet per
1,000 Btu per hour (4.8 m3per 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.
*Adjoining rooms are communication only if there
are odorless passageways or ventilation grills
between them.
DETERMINING THE TYPE OF HEATER
LOCATION SPACE:
Use this method to determine if you have a confined or
unconfined space.
Note: the space includes the room in which
you install heater plus any adjoining rooms with
doorless passageways or ventilation grills between
the rooms.
1. Find the volume of the space by multiplying room
length x width x height.
Example: Space size 18ft (length) x 18ft. (width) x 8ft.
(height) = 2592
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.
Example: 2592 cu.ft. (volume of space) / 50 cu.ft. =
51.8 or 51,800 (maximum Btu/hr the space
can support)
WARNING: If the area in which the heater may be
operated is smaller than defined as an unconfined
space or if the building is of unusually tight
construction, provide adequate combustion and
ventilation air by the methods described in the
National Fuel Gas Code, NFPA 54/ ANSI Z223.1,
Section 5.3 or applicable local codes.
SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion
Sensor (ODS) safety shut off system. The ODS/pilot
shuts off the heater if there is not enough fresh air.
IGNITION SYSTEM
PIEZO: The heater is equipped with an electronic
manual ignitor. This system requires no matches, or
other source to light heater, but does require one AA
battery to operate ignitor. (AA Battery included).
THERMOSTATIC CONTROL
These heaters have a control valve with a thermostat
sensing bulb. This results in the greatest heater comfort
and may reult in lower fuel bills.
LOCAL CODES
Install and use heater with care.
Installation must conform to local codes or in the
absences of local codes, use the latest edition of
National Fuel Gas Code ANSI Z223.1/NFPA 54.
UNPACKING
1. Remove heater from carton.
2. Remove all protective packaging applied to
heater for shipment.
3. Check heater for any shipping damage. If
heater is damaged, promptly inform dealer
where you bought heater.
FRESH AIR FOR COMBUSTION AND
VENTILATION
WARNING: This heater shall not be installed in
a confined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air. Read the following
instructions to insure proper fresh air for this and
other fuel-burning appliances in your home.
ESTABLISHING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas
Code, NFPA 54/ ANSI Z223.1, Section 5.3, Air for
Combustion 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
This heater must not be installed in a confined space
or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air.
The information on pages 3 through 5 will help you
classify your space and provide adequate ventilation.
Unusually Tight Construction
If your home meets all of the three following criteria you
must provide additional fresh air. See Ventilation Air
from Outdoors, page 5.
Unusually tight construction is defined as construction
where:
a. Walls and ceilings exposed to the outside

5Installation Instructions and Owner’s Manual
Unvented Liquid Propane Fired Room Heater
outdoors or spaces open to the outdoors. These
include attics* and crawl spaces. Follow the National
Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3,
Air for Combustion and Ventilation for required size of
ventilation grills or ducts.
*IMPORTANT: Do not provide openings for inlet or
outlet into attic. If attic has a thermostat-controlled
power vent, heated air entering the attic will activate
the power vent.
IMPORTANT: Vent-free heaters add moisture to
the air. Although this is beneficial, installing heater
in rooms without enough ventilation air may cause
mildew to form from too much moisture. See Fresh
Air for Combustion and Ventilation, pages 3
through 5.
INSTALLATION
NOTICE: This heater is intended for the use as
supplemental heat. Use this heater along with your
primary heating system. Do not install this heater as
your primary heat source. If you have a central heating
system, you may run system’s circulating blower while
using heater. This will help circulate the heat throughout
the house. In the event of a power outage, you can use
this heater as your primary heat source for the duration
of the outage.
3. Add the Btu/hr of all the fuel-burning appliances
in the space such as, Vent–free heater, Gas water
heater, Gas furnace, Vented gas heater, Gas
fireplace logs, and Other gas appliances*
*Do not include direct-vent gas appliances. Direct-
vent draws combustion air from the outdoors and
vents to the outdoors.
Example:
Gas water heater 40,000 Btu/hr
Vent Free Heater + 20,000 Btu/hr
Total =60,000 Btu/hr
4. Compare the maximum Btu/hr the space can support
with the actual amount of Btu/hr used.
Example: 51,800 Btu/hr (maximum Btu/hr the
space can support)
60,000Btu/hr(Actual amount ofBtu/hrused)
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. Your options
are as follows:
A. Rework worksheet, and the space of an adjoining
room. If the extra space provides an unconfined
space, remove door to adjoining room or add
ventilation grills between the rooms. See Ventilation
Air From Inside Building (Fig. 2)
B. Vent room directly to the outdoors. See Ventilation
Air From Outdoors (Fig. 3).
C.Install a lower Btu/hr heater if lower Btu/hr size
makes room unconfined.
If 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.
VENTILATION AIR
Ventilation from Inside Building
This fresh air would come from an adjoining unconfined
space. When ventilation to an adjoining unconfined
space, you must provide two permanent openings: one
within 12” of the ceiling and one within 12” of the floor
on the wall connecting the two spaces (see options
1 & 2 of figure 2). You can also remove door into
adjoining room (see option3, fig 2). Follow the National
Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3,
Air for Combustion and Ventilation for required size of
ventilation grills or ducts.
WARNING: Rework worksheet, adding the space
of the adjoining unconfined space. The combined
space must have enough fresh air to supply all
appliance in both spaces.
Ventilation from Outdoors
If necessary provide extra fresh air by using ventilation
grills or ducts. Connect these items directly to the

CONNECTING TO GAS SUPPLY
WARNING: A qualified service person must connect
heater to gas supply. Follow all local codes.
WARNING: This appliance requires a 3/8” NPT
(National Pipe Thread) inlet connection to the
pressure regulator. Use of floor mounting feet will
require you to use a 3/8 NPT street elbow to make
gas connection.
CAUTION: Never connect heater directly to the
Propane supply. This heater requires an external
regulator.(which is attached to the supplied hose).
Install the external regulator between the heater and
Propane/LP supply.
The external regulator will reduce the incoming gas
pressure to between 11 and 14 inches of water. If
you do not reduce incoming gas pressure heater
regulator damage could occur. Install external
regulator with the vent pointing down. Pointing the
vent down protects it from freezing rain or sleet.
CAUTION: Use only new black iron or steel pipe.
Internally-tinned copper tubing may be used in certain
areas. Check your local codes. Use pipe of larger
enough diameter to allow proper gas volume to heater.
If pipe is too small, undue loss of pressure will occur.
Installation must include an equipment shutoff valve,
union and plugged 1/8” NPT tap. Locate NPT tap within
reach of test gauge hookup. NPT tap must be upstream
from heater (see figure 11).
*A CSA/AGA certified equipment shutoff valve with
1/8” NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA/AGA certified equipment
shutoff valve from your dealer.
IMPORTANT: Install an equipment shutoff valve in an
accessible location. The equipment shutoff valve is for
turning on or shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess
sealant in pipe could result in clogged heater fuel train.
CAUTION: Use pipe joint sealant that is resistant to
LP-Gas.
Install sediment trap in supply line as shown in figure
11. Locate sediment trap where it is within reach
for cleaning. Asediment trap traps moisture and
contaminants. This keeps them from going into heater.
If sediment trap is not installed or is installed improperly,
heater may not run correctly.
IMPORTANT: Hold pressure regulator with wrench
when connecting it to gas piping and/or fittings.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections for
leaks after installing or servicing. Correct all leaks
at once.
WARNING: Never use an open flame to check for
a gas leak. Apply a mixture of liquid soap and water
to all joints. Bubbles forming show a leak. Correct
all leaks at once.

LIGHTING INSTRUCTIONS
1. STOP! Read the all safety information included
with and on the side of heater.
2. Check that gas supply to heater is on.
3. Push in gas control knob and slightly turn
clockwise to the OFF position (see figure
14).
Note: Knob cannot be turned from PILOT to OFF
unless knob is pushed in slightly. Do not force.
4. Wait five (5) minutes to clear out any gas.
Then smell for gas, including near the floor. If
you smell gas, STOP! Follow “B” in the safety
information above. If you do not smell gas, go
to the next step.
5. Push in gas control know slightly and turn
counterclockwise to PILOT/IGN and
depress for five (5) seconds.
Figure 14
Note: The first time that the heater is operated after
connecting the gas supply, the control knob should
be depressed for about 30 seconds. This will allow
air to bleed from the gas system.
6. Push in control knob and rotate control knob
back to OFF position then rotate counterclock-
wise to PILOT/IGN position. This will
light pilot. If needed gently keep rotating control
knob back and forth while depressed until pilot
lights.
7. Keep control knob depressed in for ten (10)
seconds after lighting pilot. If pilot goes out,
repeat steps 4, 5, 6 and 7.
If pilot does not stay lit, refer to Troubleshoot-
ing, pages 12-13. Also, contact a qualified
service person or gas supplier for repairs.
If control knob does not pop up when released,
contact a qualified service person or gas
supplier for repairs.
8. When the pilot is lit, turn the control knob
counterclockwise to heating level. The
main burner should light.
9. To select the desired heat level, turn the
temperature setting knob to desired comfort
setting from 1 to 5.
CAUTION: Do not try to adjust heating level by using
equipment shutoff valve.
TO TURN OFF GAS TO APPLIANCE
SHUTTING OFF HEATER:
1. Turn off equipment shutoff valve.

INSPECTING BURNER
Check pilot flame pattern and burner flame pattern
often.
PILOT FLAME PATTERN
Figure 15 shows a correct pilot flame pattern and
incorrect pilot flame pattern. The incorrect pilot flame
pattern is not touching thermocouple. This will cause
the thermocouple to cool. When the thermocouple
cools, the heater will shut down. If pilot flame pattern is
incorrect, as shown in Figure 15:
• Turn heater off (see To Turn OFF Gas to
Appliance, page 10.
• See Troubleshooting, pages 12-13.

CLEANING AND MAINTENANCE
WARNING: Turn off heater and let cool before
servicing.
CAUTION: You must keep control areas, burner and
circulation air passageways of heater clean. Inspect
these areas of heater before use. Have the heater
inspected yearly by a qualified service person. Heater
may need more frequent cleaning due to excess lint
from carpeting, bedding material, pet hair, etc.
Make sure grille guard is in place before running
heater. If screen or grille guard is removed for servicing
it must be replaced prior to operating the heater.
WARNING: Failure to keep the primary air
opening(s) of the burner(s) clean may result in
sooting and property damage.
CLEANING ODS/PILOTAND BURNER
• Use as vacuum cleaner, pressurized air or
small soft bristled brush to clean.
CLEANING BURNER PILOTAIR HOLE INLET
We recommend that you clean the unit every 2,500
hours of operation or every three months. We also
recommend that you keep the burner tube and pilot
assembly clean and free of dust and dirt. To clean these
parts we recommend using compressed air no greater
than 30 psig.
This can be done by using a vacuum cleaner in the
blow position, using compressed air in a can, please
follow the directions on the can. If you don’t follow
directions on the can you could damage the burner or
pilot assembly. In addition, the directions that follow
should also be followed.
1. Shut off the unit, including the pilot.Allow the
unit to cool for at least thirty minutes.
2. Inspect burner and pilot for dust and dirt.
3. Blow air through the port/slots and holes in the
burner.
A yellow tip on the pilot flame indicates dust and dirt in
the pilot assembly. To clean the pilot assembly find the
small pilot air inlet hole about two inches from where
the pilot flame comes out of the pilot assembly (see
figure 16). With the unit off, lightly blow air through the
air inlet hole. You may blow through a drinking straw if
compressed air is not available.
