for every 1,000 BTU's of gas burner capacity.

W A R N I N G S

ANY ALTERATION TO THE ORIGINAL DESIGN, INSTALLED OTHER THAN AS SHOWN IN THESE
INSTRUCTIONS, OR USED WITH A TYPE OF GAS NOT SHOWN ON THE RATING PLATE IS PROHIBITED
AND VOIDS THE WARRANTY.

The installation must conform to local codes. In the absence of local codes, the installation must conform
to the National Fuel Gas Code, also known as NFPA 54 and ANSI Z223.1 - latest edition. Installation and
service must be performed by a qualified installer (i.e., a licensed heating contractor or gas company
personnel).
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 bedrooms or
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

-1-

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 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. 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/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

3

than 50 ft

per 1,000 BTU/Hr (4.8 m3/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 space.

20.

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/NFPA54, Air for
Combustion and Ventilation, or applicable
codes.

21. 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.

22. 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 1 perm (6x10-11 kg
per pa-sec-m2)or less with opeings gasketed
or sealed;

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 plumbing,
electrical, and gas lines, and other openings.

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
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 ft

LENGTH x WIDTH x HEIGHT = ___________________________ Ft

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

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
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

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 LP-Gas
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 LP-Gas.

 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

LP-GAS WARNING ODOR

NO ODOR DETECTED - ODOR FADE

SOME POINTS TO REMEMBER

point by point with the members of your household. 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 re­enter 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.

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 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.
