DANGER: Households with small children, disabledor elderly persons may require a 120°F (49°C) or lowertemperature setting to prevent contact with “HOT” water.Maximum water temperature occurs while burner is on.To find water temperature being delivered, turn on a hotwater faucet and place a thermometer in the water streamand read the thermometer. (See page 26 & 27 for moredetails.)The temperature of the water at the outlet of the waterheater can be regulated by setting the temperature onRemote Control. The remote control was set at 100°F(38°C) before it was shipped from the factory.The diagram to the bottom left illustrates the RemoteControl and how to adjust the water temperature.Notice: The factory setting allows operating temperaturesbetween 100°F (38°C) and 120°F (49°C). Temperaturesof 85°F (29°C) and above 120°F (49°C) can be achievedwith the MAIN (UMC-117) remote control. Temperaturesof 85°F (29°C) can be achieved with the Bath (USC-117or USC2-117) remote control. Only qualified servicepersonnel should perform this adjustment. Only factoryauthorized remote control(s) should be used.Notice: When this water heater is supplying generalpurpose hot water requirements for use by individuals,a thermostatically controlled mixing valve for reducingpoint of use water temperature is recommended to reducethe risk of scald injury. Contact a licensed plumber or thelocal plumbing authority for further information.Notice: Only commercial products can achievetemperatures up to 185° (85° C).AP14558-1 (09_08) DV 66 Manual.indd 49/17/2008 3:07:52 PM
DANGER!Natural gas and liquefied petroleum modelsBoth LP and natural gas have an odorant added to aid in detecting a gas leak. Somepeople may 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 or camouflagea gas leak.● Water heaters utilizing LP gas are differentfrom natural gas models. A natural gaswater heater will not function safely on LPgas and vice versa.● No attempt should ever be made toconvert the water heater from natural gasto LP gas. To avoid possible equipmentdamage, personal injury or fire, do notconnect the water heater to a fuel type notin accordance with the unit data plate;propane for propane units and natural gasfor natural gas units. These units are notcertified for any other fuel type.● LP appliances should not be installed belowgrade (for example, in a basement) if suchinstallation is prohibited by federal, stateand/or local laws, rules, regulations orcustoms.● Propane or LP gas must be used with greatcaution. It is heavier than air and willcollect first in lower areas, making it hardto detect at nose level.● Before attempting to light the water heater,make sure to look and smell for gas leaks.Use a soapy solution to check all gas fittingsand connections. Bubbling at a connectionindicates a leak that must be corrected.When smelling to detect a gas leak, be sureto sniff near the floor also.● Gas detectors are recommended in LPand 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 leaksin gas applications.Notice: If a gas leak is present or suspected:● Do not attempt to find the cause yourself.● Do not try to light any appliance.● Do not touch any electrical switch.● Do not use any phone in your building.● Leave the building immediately and makesure your family and pets leave also.● Leave the doors open for ventilation andcontact the gas supplier, a qualified serviceagency or the fire department.● Stay away from the building until theservice call has been made, the leak iscorrected and a qualified agency hasdetermined the area to be safe.5AP14558-1 (09_08) DV 66 Manual.indd 59/17/2008 3:07:52 PM
