FUEL GAS ODOR

Propane gas and natural gas has man-made odorant 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 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 heater for you.

ODOR FADING -- NO ODOR DETECTED

■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 this fuel gas.

■Learn to recognize the odor of propane gas or natural gas. Local propane 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.

■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.

■Smoking can decrease your ability to smell. Being

around an odor for a period of time can affect your ■ Always be sensitive to the slightest gas odor. If you

sensitivity to that particular odor. Odors present in animal confinement buildings can mask fuel gas odor.

continue to detect any gas odor, no matter how small, treat it as a serious leak. Immediately go into action as discussed previously.

ATTENTION -- CRITICAL POINTS TO REMEMBER!

■Propane gas and natural gas has a distinctive odor. Learn to recognize this odor. (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 the heater, perform service or repairs, or make any adjustments to the heater on a propane gas

6 or fuel system.

■Even if you are not properly trained in the service and repair of radiant heaters, 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!

6. Ensure the heater installation does not interfere with water, gas, or electrical lines.

7. Position the gas hose to prevent any contact with the tubes, heat relectors, and burner box.

8.Ensure that all accessories that ship with the heater have been removed from shipping containers and installed. This pertains to gas hose, regulators, supports, hangers, etc.

9.This heater requires a regulated gas supply to its gas inlet :

--The regulator must be the proper design for the application.

--The regulator must control the inlet pressure to the heater within the range specified on the dataplate.

--Regulators mounted outside must be protected from adverse weather conditions.

--Regulators with pressure relief valves should be installed outside the building.

--Regulator installed inside should be vented outside.

--Local state and national codes apply to regulator installation. Refer to NFPA 54, National Fuel Gas Code, and NFPA 58, Standard for Storage and Handling of Liquified Petroleum Gas.

10.Always use pipe joint compound that is resistant to liquefied petroleum gas and natural gas.

11.Check all connections for gas leaks using approved gas leak detectors. Gas leak testing is performed as follows:

WARNING

Fire and Explosion Hazard

■Do not use open flame (matches, torches, candles, etc.) in checking for gas leaks.

■Use only approved leak detectors.

■Failure to follow this warning can lead to fires or explosions.

■Fires or explosions can lead to property damage, injury or death.

--Check all pipe connections, hose connections, fittings and adapters upstream of the gas control with approved gas leak detectors.

--In the event a gas leak is detected, check the components involved for cleanliness and proper application of pipe compound before further tightening.

--Tighten the gas connections as necessary to stop the leak.

--After all connections are checked and any leaks are stopped, turn on the main burner.

--Stand clear while the main burner ignites to prevent injury caused from hidden leaks that could cause flashback.

--With the main burner in operation, check all connections, hose connections, fittings and joints as well as the gas control valve inlet and outlet connections with approved gas leak detectors.

--If a leak is detected, check the components involved for cleanliness in the thread areas and proper application of pipe compound before further tightening.

--Tighten the gas connection as necessary to stop the leak.

--If necessary, replace the parts or components involved if the leak cannot be stopped.

--Ensure all gas leaks have been identified and repaired before proceeding.

12.Install a sediment trap at the gas valve inlet to prevent foreign materials (pipe compound, pipe chips and scale) from entering the gas valve. Debris blown into the gas valve may cause that valve to malfunction resulting in a serious gas leak that could result in a possible fire or explosion causing loss of products, building or even life. A properly installed sediment trap will keep foreign materials from entering the gas valve and protect the safe functioning of that important safety component.

13.Any heater connected to a piping system must have an accessible, approved manual shut off valve installed within six feet (6 ft.) of the heater it serves.
