!DANGER!LIQUEFIED PETROLEUM (LP PROPANE OR BUTANE)AND NATURAL GAS MODELSLP and Natural gas have an odorant added to aid in detecting a gas leak. Some peoplemay not physically be able to smell or recognize this odorant. If you are unsure orunfamiliar with the smell of LP or natural gas, ask the gas supplier. Other conditions,such as “odorant fade”, which causes the odorant to diminish in intensity, can also hide orcamouflage a gas leak. Water heaters utilizing LP gas aredifferent from natural gas models. Anatural gas water heater will not functionsafely on LP gas and vice versa.! DANGER: If a gas leak is present orsuspected: No attempt should ever be made toconvert the water heater from naturalgas to LP gas. To avoid possibleequipment damage, personal injury orfire, do not connect the water heater to afuel type not in accordance with the unitdata plate. LP for LP units. Natural gasfor natural gas units. These units are notcertified for any other fuel type. Do not try to light any appliance. LP appliances should not be installedbelow grade (for example, in a basement)if such installation is prohibited byfederal, state and/or local laws, rules,regulations or customs. Do not attempt to find the cause yourself. Do not touch any electrical switch. Do not use any phone in your building. Leave the house immediately and makesure your family and pets leave also. Leave the doors open for ventilationand contact the gas supplier, a qualifiedservice agency or the fire department. Stay away from the house (or building)until the service call has been made, theleak is corrected and a qualified agencyhas determined the area to be safe. LP gas must be used with great caution.It is heavier than air and will collect firstin lower areas making it hard to detect atnose level. Before attempting to light the waterheater, make sure to look and smell forgas leaks. Use a soapy solution to checkall gas fittings and connections. Bubblingat a connection indicates a leak that mustbe corrected. When smelling to detect agas leak, be sure to sniff near the flooralso. Gas detectors are recommended in LP& natural gas applications and theirinstallation should be in accordancewith the detector manufacturer’srecommendations and/or local laws,rules, regulations or customs. It is recommended that more than onemethod, such as soapy solution, gasdetectors, etc., be used to detect leaks ingas applications.5
