Propane 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 gas tank or cylinder fuel supply
valves, or the main fuel supply valve located at the meter if you use natural gas.
■ Propane 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.
■ Natural gas is lighter than air and can collect around
rafters or ceilings.
■ 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.
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.
■ 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
■ Some people cannot smell well. Some people cannot
smell the odor of the man-made chemical added to propane or natural gas. You must determine if you can smell the odorant in these fuel gases.
■ Learn to recognize the odor of propane gas and natural
gas. Local propane gas dealers and your local natural gas supplier (utility) 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.
■ The odorant in propane 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 gas odor may differ in intensity at different
levels. Since propane 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 gas and natural gas have 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 gas and natural gas fueled heaters, then do not attempt to light heater, perform service or repairs, or make any adjustments to the heater on propane gas or natural 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 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!
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.
Also refer to:
-- ANSI/NFPA 58, latest edition, Standard for Storage and Handling of Liquefied Petroleum Gas
-- ANSI Z223.1/NFPA 54, National Fuel Gas Code
3. Adequate ventilation air for combustion must be provided in accordance with OSHA 29 CFR 1926.154, Temporary Heating Devices, and ANSI A10.10, Safety Requirements for Temporary and Portable Space Heating Devices.
4. We cannot anticipate every use which may be made of our heater. Check with your local fire safety authority if you have questions about applications.
5. Other standards govern the use of fuel gases and heat producing products in specific applications. Your local authority can advise you about these.
6. Use only compressed air, soft brush or dry cloth to clean the interior of the heater and it’s components.
7. Always use approved pipe thread compound suitable for use with propane gas on the threaded connections.
8. 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.
9. 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 building materials, and contact with hot surfaces during use. The hose assembly shall be that specified by the manufacturer. See parts list.
10. Check for gas leaks and proper function upon heater installation or when relocating. Refer to leak check instructions within installation section of this manual.
11. This heater should be inspected for proper operation by a qualified service person before each use and at least annually.
12. Always turn off the gas supply to the heater if the heater is not going to be used in the heating of the work space.
13. If gas flow is interrupted and flame goes out, do not relight the heater until you are sure that all gas that may have accumulated has cleaned away. In any event, do not relight the heater for at least 5 minutes.
14. Minimum propane 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.
15. When the heater is to be stored indoors, the connection between the propane gas supply cylinder(s) and the heater must be disconnected and the cylinder(s) removed from the heater and stored in accordance with the Standard and Handling of Liquefied Petroleum Gases, ANSI/NFPA 58.
16. Propane gas supply containers have left handed threads. Always use the appropriate wrench to tighten or loosen the P.O.L. fitting at the propane gas containers supply valve. Do not use pliers.
WARNING
