7 Do not use this radiant brood 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 must be provided to support the combustion air requirements of the brood heater being used. LPG and natural gas have a 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 LPG tank or cylinder fuel supply valves, or the main fuel supply valve if you use natural gas. LPG 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. Some people cannot smell well. Some people cannot smell the odor of the man-made chemical added to LPG or natural gas. You must determine if you can smell the odorant in this fuel gas. Learn to recognize the odor of LPG 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. 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. LPG and natural gas has a distinctive odor. Learn to recognize this odor. (Reference Fuel Gas Odor and Odor Fading sections above. WARNING Asphyxiation Hazard Safety Precautions Refer to the specification section of the Owner s Manual, heater s 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 carbon monoxide poisoning in humans leading to serious injury or death. Symptoms of carbon monoxide poisoning can include headaches, dizziness and difficulty in breathing. Symptoms of improper ventilation affecting livestock can be disease, lower feed conversion, or death. FUEL GAS ODOR 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 brood heater for you. ODOR FADING -- NO ODOR DETECTED The odorant in LPG 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. LPG 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. ATTENTION -- CRITICAL POINTS TO REMEMBER! Even if you are not properly trained in the service and repair of brood heaters, ALWAYS be consciously aware of the odors of propane gas and natural gas. If you have not been properly trained in repair and service of LPG and natural gas fueled brood heaters, then do not attempt to light the brood heater, perform service or repairs, or make any adjustments to the brood heater on a propane gas or fuel system. 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
