LP gas and natural gas have man-made odorants added specifically for detection of fuel gas leaks.
If a gas leak occurs, you should be able to smell the fuel gas.
THAT’S YOUR SIGNAL TO GO INTO IMMEDIATE ACTION!
■ Do not take any action that could ignite the fuel gas. Do
not operate any electrical switches. Do not pull any
power supply or extension cords. Do not light matches
or any other source of flame. Do not use your
telephone.
■ Get everyone out of the building and away from the area
immediately.
■ Close all propane (LP) gas tank or cylinder fuel supply
valves, or the main fuel supply valve located at the
meter if you use natural gas.
■ Propane (LP) gas is heavier than air and may settle in
low areas. When you have reason to suspect a propane
leak, keep out of all low areas.
■ Use your neighbor’s phone and call your fuel gas
supplier and your fire department. Do not re-enter the
building or area.
■ Stay out of the building and away from the area until
declared safe by the firefighters and your fuel gas
supplier.
■ FINALLY, let the fuel gas service person and the
firefighters check for escaped gas. Have them air out
the building and area before you return. Properly
trained service people must repair the leak, check for
further leakages, and then relight the appliance for you.
■ Some people cannot smell well. Some people cannot
smell the odor of the man-made chemical added to
propane (LP) or natural gas. You must determine if you
can smell the odorant in these fuel gases.
■ Learn to recognize the odor of propane (LP) gas and
natural gas. Local propane (LP) gas dealers will be
more than happy to give you a scratch and sniff
pamphlet. Use it to become familiar with the fuel gas
odor.
■ Smoking can decrease your ability to smell. Being
around an odor for a period of time can affect your
sensitivity to that particular odor. Odors present in
animal confinement buildings can mask fuel gas odor.
■ The odorant in propane (LP) gas and natural gas is
colorless and the intensity of its odor can fade under
some circumstances.
■ If there is an underground leak, the movement of gas
through the soil can filter the odorant.
■ Propane (LP) gas odor may differ in intensity at different
levels. Since propane (LP) gas is heavier than air, there
may be more odor at lower levels.
■ Always be sensitive to the slightest gas odor. If you
continue to detect any gas odor, no matter how small,
treat it as a serious leak. Immediately go into action as
discussed previously.

Safety Precautions
FUEL GAS ODOR
ODOR FADING -- NO ODOR DETECTED
ATTENTION -- CRITICAL POINTS TO REMEMBER!
■ Propane (LP) gas has a distinctive odor. Learn to
recognize these odors. (Reference Fuel Gas Odor and
Odor Fading sections above.
■
If you have not been properly trained in repair and service
of propane (LP) gas then do not attempt to light heater,
perform service or repairs, or make any adjustments to
the heater on the propane (LP) gas fuel system.
■ Even if you are not properly trained in the service and
repair of the heater, ALWAYS be consciously aware of
the odors of propane (LP) gas and natural gas.
■ A periodic sniff test around the heater or at the
heater’s joints; i.e. hose, connections, etc., is a good
safety practice under any conditions. If you smell even
a small amount of gas, CONTACT YOUR FUEL GAS
SUPPLIER IMMEDIATELY. DO NOT WAIT!
WARNING
■ Do not use this heater for heating human living
quarters.
■ Do not use in unventilated areas.
■ The flow of combustion and ventilation air must not be
obstructed.
■ Proper ventilation air must be provided to support the
combustion air requirements of the heater being used.
■ Refer to the specification section of the heater’s
Owner’s Manual, heater dataplate, or contact the L.B.
White Company to determine combustion air ventilation
requirements of the heater.
■ Lack of proper ventilation air will lead to improper
combustion.
■ Improper combustion can lead to carbon monoxide
poisoning leading to serious injury or death. Symptoms
of carbon monoxide poisoning can include headaches,
dizziness and difficulty in breathing.
Asphyxiation Hazard
1. Do not attempt to install, repair, or service this heater
or the gas supply line unless you have continuing
expert training and knowledge of gas heaters.
Qualifications for service and installation of this
equipment are as follows:
a.
To be a qualified gas heater service person, you
must have sufficient training and experience to
handle all aspects of gas-fired heater installation,
service and repair. This includes the task of
installation, troubleshooting, replacement of
defective parts and testing of the heater. You
must be able to place the heater into a continuing
safe and normal operating condition. You must
completely familiarize yourself with each model
heater by reading and complying with the safety
instructions, labels, Owner’s Manual, etc., that is
provided with each heater.
b.
To be a qualified gas installation person, you must
have sufficient training and experience to handle
all aspects of installing, repairing and altering gas
lines, including selecting and installing the proper
equipment, and selecting proper pipe and tank
size to be used. This must be done in accordance
with all local, state and national codes as well as
the manufacturer’s requirements.
2. All installations and applications of L.B. White heaters
must meet all relevant local, state and national
codes. Included are L.P. gas, natural gas, electrical,
and safety codes. Your local fuel gas supplier, a local
licensed electrician, the local fire department or
similar government agencies, or your insurance agent
can help you determine code requirements.
-- ANSI/NFPA 58, latest edition, Standard for
Storage and Handling of Liquefied Petroleum
Gas and/or
-- ANSI Z223.1/NFPA 54, National Fuel Gas
Code
3. We cannot anticipate every use which maybe made of
our heaters. Check with the local fire safety authority
if you have questions about applications.
4. The heater shall be installed so that it is not directly
exposed to water spray, rain, or dripping water.
5. Do not locate fuel gas containers or fuel supply
hoses anywhere near the discharge outlet of the
heater.
6. Do not block air intakes or discharge outlets of the
heater. Doing so may cause improper combustion or
damage to heater components leading to property
damage.
7. The hose assembly shall be visually inspected on a
daily basis after heater relocation and when the
heater is in use. If it is evident there is excessive
abrasion or wear, or if the hose is cut, it must be
replaced prior to the heater being put into operation.
The hose assembly shall be protected from building
materials, and contact with hot surfaces during use.
The hose assembly shall be that specified by the
manufacturer. See parts list.
8. Check for gas leaks and proper function upon heater
installation, when relocating, and after servicing.
Refer to leak check instructions within installation
section of this manual.
9. This heater should be inspected for proper operation
by a qualified service person before each use and at
least annually.
10. Always turn off the gas supply to the heater if the
heater is not going to be used in the heating of the

11. If gas flow is interrupted and flame goes out, do not
relight the heater until you are sure that all gas that
may have accummulated has cleared away. In any
event, do not relight the heater for at least 5 minutes.
12. Minimum LP gas supply cylinder size to be used shall
be 100 pounds when using a cylinder supply system.
The system must be arranged to provide vapor
withdrawal from the operating cylinder.
13. When the heater is to be stored indoors, the
connection between the L.P. gas supply cylinder(s)
and the heater must be disconnected and the
cylinder(s) removed form the heater and stored in
accordance with Chapter 5 if the Standard for the
Storage and Handling of Liquified Petroleum Gases,
ANSI/NFPA 58.
