12409-2-0403

WARNING

CARBON MONOXIDE POISONING MAY LEAD TO
DEA TH.

Early signs of carbon monoxide poisoning resemble the flu,
with headache, dizziness and/or nausea. If you have these
signs, heater may not be working properly . Get fresh air at
once! Have heater serviced.

Some people – pregnant women, persons with heart or lung
disease, anemia, those under the influence of alcohol, those
at high altitudes – are more affected by carbon monoxide
than others.

The pilot light safety system senses the depletion of oxygen
at its location. If this heater is installed in a structure having
a high vertical dimension, the possibility exists that the
oxygen supply at the higher levels will be less than that at
the heater . In this type of application, a fan to cir culate the
structure air will minimize this effect. The use of this fan
will also improve the comfort level in the structure. When
a fan is used to circulate air , it should be located so that the
air flow is not directed at the burner.

SAFETY INFORMATION FOR USERS OF LP-GAS

Propane (LP-Gas) is a flammable gas which 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

LP-GAS WARNING ODOR

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, use your
phone. 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 to be safe.

NO ODOR DETECTED - ODOR FADE

Some people cannot smell well. Some people cannot smell the
odor of the chemical 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.
Odorants in LP-Gas also are subject to oxidation. This fading can

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 phone 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.

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 earlier.

SOME POINTS TO REMEMBER

• 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 or 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, perform service, or make adjustments in an 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 adsorption 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

Page 4

to set too long before refilling. Cylinders and tanks which
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
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.

GENERAL INFORMATION

This is an unvented gas-fired heater. It uses air (oxygen) from the
room in which it is installed. Provisions for adequate combustion
and ventilation air must be provided.

Keep room area clear and free from combustible materials, gaso­line and other flammable vapors and liquids.

Unvented gas heaters are a supplemental zone heater. They are
not intended to be a primary heating appliance. Water vapor pro­duced by an unvented heater can create moisture problems in a
home when operated for extended periods of time.

During manufacturing, fabricating and shipping, various compo­nents of this appliance are treated with certain oils, films or bond­ing agents. These chemicals are not harmful but may produce
annoying smoke and smells as they are burned off during the ini­tial operation of the appliance; possibly causing headaches or eye
or lung irritation. This is a normal and temporary occurrence.

The initial break-in operation should last 2-3 hours with the burner
at the highest setting. Provide maximum ventilation by opening
windows or doors to allow odors to dissipate. Any odors remain­ing after this initial break-in period will be slight and will disap­pear with continued use.

This appliance must not be used with glass doors in the closed
position. This can lead to pilot outages and severe sooting out­side the fireplace.

Do not use this room heater if any part has been under water.
Immediately call a qualified service technician to inspect the room
heater and replace any part of the control system and any gas
control which has been under water.

Before you get started

Carefully inspect the contents for shipping damage. If any parts
are missing or damaged, immediately inform the dealer from
whom you purchased the appliance. Do not attempt to install any
part of the appliance unless you have all parts in good condition.

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS

Water vapor is a by-product of gas combustion. An unvented
room heater produces approximately one (1) ounce (30ml) of
water for every 1,000 BTU's (.3KW's) of gas input per hour.

Unvented room heaters are recommended as supplemental heat (a
room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.

The following steps will help insure that water vapor does not
become a problem.

1. Be sure the heater is sized properly for the application, includ­ing ample combustion air and circulation air.

2. If high humidity is experienced, a dehumidifier may be used to
help lower the water vapor content of the air.

3. Do not use an unvented room heater as the primary heat source

Exhaust fans, fireplaces, clothes dryers and fuel burning appli­ances draw air from the house to operate. You must provide
adequate fresh air for these appliances. This will insure proper
venting of vented fuel-burning appliances.

PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR

This heater shall not be installed in a confined space unless pro­visions are provided for adequate combustion and ventilation air.

The National Fuel Gas Code defines a confined space as a space
whose volume is less than 50 cubic feet per 1,000 Btu per hour
(4.8m3 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
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

The air that leaks around doors and windows may provide enough
fresh air for combustion and ventilation. However, in buildings of
unusually tight construction, you must provide additional fresh
air.

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 one perm
or less with openings gasketed or sealed, and

b. Weatherstripping 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 at

other openings.
If your home meets all of the three criteria above, 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 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, ANSI Z223.1, Section 5.3. or applicable local
codes.

The following formula can be used to determine the maximum
heater rating per the definition of unconfined space:

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, Section 5.3.
