Read this Installation and Owners Guide carefully and completely before attempting to install, operate
or service this heater. Improper use of this heater can result in serious bodily injury or death due to
hazards of fire, explosion, electrical shock or carbon monoxide poisoning. When used without fresh
air, this heater may give off CARBON MONOXIDE, an odorless, poisonous gas. CARBON MONOXIDE
POISONING MAY LEAD TO DEATH! Early signs of carbon monoxide poisoning resemble the flue with
headache, dizziness and/or nausea. If you have these signs, the heater may not be working properly.
Get fresh air at once, and have the heater serviced. Some people such as pregnant women, persons
with heart or lung disease, anemia, those under the influence of alcohol, and those at higher altitudes
are more affected by carbon monoxide than others. Retain this manual for future reference. It is your
guide to many years of a proper and safer operation of the heater.
1. This is a heating appliance any safety screen
or guard removed for servicing an appliance
must be replaced prior to operating the
appliance.
2. Children and adults should be alerted to the
hazard of high surface temperatures and
should stay away to avoid burns or clothing
ignition.
3. Young children should be carefully
supervised when they are in the room with
the heater.
4. Do not install this heater at altitudes above
5000 ft. because shutdown of the heater by
the ODS system may occur due to reduced
oxygen levels at these altitudes.
5. This appliance is only for use with the type
of gas indicated on the nameplate. THIS
APPLIANCE IS NOT CONVERTIBLE FOR USE
WITH OTHER GASES. Please check the gas
type shown on the heater nameplate prior to
hooking the heater to the gas supply.
6. DO NOT install this heater in bathrooms. The
maximum input for use in bathrooms in
6,000 Btu/hr and 10,000 Btu/hr in
bedrooms where not prohibited by local
codes.
7. LPG containers (Propane cylinders) must not
be used or stored indoors.
8. DO NOT install this heater directly onto an
LPG container or propane cylinder without
directions from your propane company
because high gas pressure can damage this
heater.
9. Always operate the heater at the OFF, P or
one of the three locked positions. Never
operate the heater at any setting between
these locked positions, as this may result in
improper combustion.
10. DO NOT locate this heater in high traffic
areas or in windy or drafty locations.
11. Keep the area near the heater free from
combustible materials, gasoline, and other
flammable vapors and liquids.
12. DO NOT use this heater if any part has been
under water. Immediately call a qualified
service person to inspect the room heater
and to replace any part of the control
system and any gas control that has been
under water.
13. This heater has a pilot light safety system
that turns off the heater if enough fresh air
is not available. The pilot light safety
section on this unit does not sense the
presence of carbon monoxide. It senses the
depletion of the oxygen supply used in the
combustion process. Combustion of gas
with a depleted oxygen supply is one source
of carbon monoxide.
14. If this heater is installed in a room having a
high vertical dimension, a fan to circulate
the air is recommended to improve the
comfort level in the room. When a fan is
used to circulate air, it should be located so
that the airflow is not directed at the burner.
15. If installed in a garage, this heater must be
wall mounted only. The bottom of the
-1-
heater must be a minimum of 18" above the
finished floor.
16. A vent-free gas heater will increase the
amount of humidity in the room in which it
is installed.
17. A fresh air opening for combustion and
ventilation air must be provided in the room
where the heater is installed. The opening
must have at least one square inch of free
air opening per 1,000 Btu/hr of gas
consumption for the total input rating of all
gas equipment in the space.
18. This heater 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
codes.
19. WARNING: If the area in which the heater
may be operated does not 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 /
NFPA 54, the International Fuel Gas Code, or
applicable local codes.

COMBUSTION AND VENTILATION AIR
REQUIREMENT WORKSHEET
The purpose of this worksheet is to help you determine if you are planning to install this heater in an
“unconfined” or a “confined” space. An “unconfined” space is one that is large enough to meet all the
combustion and ventilation air requirements of all the fuel burning appliances to be in operation in this space.
No additional air requirements are needed. A “confined” space is one that is not large enough to meet the
combustion and ventilation air requirements for all the fuel burning appliances in that space. As a result,
additional air is required in this space to meet the appliance needs. Check with your installer on ways to
accomplish this, or use a smaller Btu/hr input heater.
STEP 1: Determine the volume of the space in which the heater is to be installed. Include adjoining rooms
with doorless passageways. Example: 24' (long) x 16' (wide) x 8' (high) = 3072 ft3.
LENGTH x WIDTH x HEIGHT = ___________________________ Ft3
STEP 2: Multiply the volume of the space (calculated in Step 1) by 20 Btu/hr to determine the maximum
Btu/hr that the space can support without additional combustion and ventilation air provided.
Result from Step 1 ____________________ x 20 Btu/hr = ____________________ Btu/hr
STEP 3: Add the Btu/hr inputs of all fuel burning appliances in this space. NOTE: DO NOT include Direct-
Vent gas appliances because these have sealed combustion systems that draw combustion air
from outdoors. Examples of appliances to consider include: gas ranges, gas water heaters, gas
logs, kerosene heaters, etc.
Proposed Vent-Free Heater ______________________________ Btu/hr
Fuel Burning Appliance #1 ______________________________ Btu/hr
Fuel Burning Appliance #2 ______________________________ Btu/hr
TOTAL ______________________________ Btu/hr
STEP 4: Compare the results from Step 2 and Step 3.
If the result from Step 2 is greater then the result from Step 3, the area where the heater is to be
installed can be classified as an “unconfined space.” This means that the space is capable of
handling the combustion and ventilation air requirements of the existing fuel burning appliance(s)
and the proposed heater.
If the result from Step 2 is less than the result from Step 3, the area where the heater is to be
installed is classified as a “confined space.” This means that either additional combustion and
ventilation air must be provided into this space (use one of the methods described in the National
Fuel Gas Code, ANSI Z223.1 - latest edition) or the size of the proposed heater must be reduced
so that the above calculations show the space to be an “unconfined space.”

SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a flammable gas that can cause fires
and explosions. In its natural state, propane is odorless
and colorless. You may not know all the following safety
precautions, which can protect both you and your family
from an accident. Read them carefully now, then review
them point by point with the members of your household.
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
! Do not operate electric switches, light matches, or use your
telephone. Do not do anything that could ignite the gas.
! Get everyone out of the building, vehicle, trailer or area. Do
that IMMEDIATELY.
! Close all gas tank or cylinder supply valves.
! LP-Gas is heavier than air and may settle in low areas such as
basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
firefighters declare them safe.
Some people cannot smell well. Some people cannot smell the
odor of the chemical stench put into the gas. You must find out if
you can smell the odorant in propane. Smoking can decrease
your ability to smell. Being around an odor for a time can affect
your sensitivity or ability to detect that odor. Sometimes other
odors in the area mask the gas odor. People may not smell the
gas odor or their minds are on something else. Thinking about
smelling a gas odor can make it easier to smell.
The odorant in LP-Gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can filter the odorant.
Learn to recognize the odor of LP-Gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it
to find out what the propane odor smells like. If you suspect
that your LP-Gas has a weak or abnormal odor, call your LPGas Dealer.
If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualified, consciously think about the
odor of LP-Gas prior to and while lighting pilot lights or
performing service of making adjustments.
Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights in the area where the conditions are such that
you may not detect the odor if there has been a leak of LPGas.
Odor fade, due to oxidation by rust or absorption on walls of
new cylinders and tanks, is possible. Therefore, people
should be particularly alert and careful when new tanks or
cylinders are placed in service. Odor fade can occur in new
tanks, or reinstalled old tanks, if they are filled and allowed
to sit too long before refilling. Cylinders and tanks that have
been out of service for a time may develop internal rust,
which will cause odor fade. If such conditions are suspected
to exist, a periodic sniff test of the gas is advisable. If you
have any question about the gas odor, call your LP-Gas
dealer. A periodic sniff test of the LP-Gas is a good safety
LP-GAS WARNING ODOR
NO ODOR DETECTED - ODOR FADE
SOME POINTS TO REMEMBER
Someday when there may not be a minute to lose,
everyone's safety will depend on knowing exactly what to
do. If, after reading the following information, you feel you
still need more information, please contact your gas
supplier.
! Use your neighbor's telephone and call a trained LP-Gas
service person and the fire department. Even though you
may not continue to smell gas, do not turn on the gas again.
Do not re-enter the building, vehicle, trailer or area.
! Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
Odorants in LP-Gas also are subject to oxidation. Odor fading can
occur if there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into
walls, masonry and other materials and fabrics in a room. That
will take some of the odorant out of the gas, reducing its odor
intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest
gas odor. If you detect any odor, treat it as a serious leak.
Immediately go into action as instructed above.
measure under any condition.
If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the
same immediate action recommended above for the
occasion when you do detect the odorized LP-Gas.
If you experience a complete "gas out" (the container is
under no vapor pressure), turn the tank valve off
immediately. If the container valve is left on, the container
may draw in some air through openings such as pilot light
orifices. If this occurs, some new internal rusting could
occur. If the valve is left open, then treat the container as a
new tank. Always be sure your container is under vapor
pressure by turning it off at the container before it goes
completely empty or having it refilled before it is completely
empty.
