DANGER DANGER indicates an imminently hazardous situation which, if not avoided, will result in injury or death. WARNING WARNING indicates a potentially hazardous situation which, if not avoided, could result in injury or death. CAUTION CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury.

Read and understand this instruction manual and the safety messages herein before installing, operating or servicing this water heater. Explosion Hazard Overheated water can cause water tank explosion. Failure to follow these instructions and safety messages could result in death or serious injury. Properly sized temperature and pressure relief valve must be installed in the opening provided. This manual must remain with the water heater. Water temperature over 125°F (52°C) can cause severe burns instantly resulting in severe injury or death. CAUTION Improper installation, use and service may result in property damage. Children, the elderly and the physically or mentally disabled are at highest risk for scald injury. Feel water before bathing or showering. Temperature limiting devices such as mixing valves must be installed when required by codes and to ensure safe temperatures at fixtures. 4 Do not operate water heater if flood damaged. Inspect and anode rods regularly, replace if damaged. Install in location with drainage. Fill tank with water before operation. Properly sized thermal expansion tanks are required on all closed water systems. Refer to this manual for installation and service. GENERAL SAFETY INFORMATION Fire or Explosion Hazard Fire Hazard Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance. For continued protection against risk of fire: Avoid all ignition sources if you smell gas. Do not expose water heater controls to excessive gas pressure. Do not install water heater on carpeted floor. Do not operate water heater if flood damaged. Use only the gas shown on the water heater rating label. Maintain required clearances to combustibles. Keep ignition sources away from faucets after extended periods of non-use. Fire and Explosion Hazard Read instruction manual before installing, using or servicing water heater. Use joint compound or Teflon tape compatible with propane gas. Leak test before placing the water heater in operation. Disconnect gas piping and main gas shutoff valve before leak testing. Install sediment trap in accordance with NFPA 54. Breathing Hazard - Carbon Monoxide Gas Do not obstruct water heater air intake with insulating blanket. Gas and carbon monoxide detectors are available. Fire and Explosion Hazard Install water heater in accordance with the instruction manual. Do not use water heater with any gas other than the gas shown on the rating label. Excessive gas pressure to gas valve can cause serious injury or death. Turn off gas lines during installation. Contact a qualified installer or service agency for installation and service. Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual. CAUTION Property Damage Hazard All water heaters eventually leak. Do not install without adequate drainage. Jumping out control circuits or components can result in property damage, personal injury or death. Electrical Shock Hazard Turn off power to the water heater before performing any service. Label all wires prior to disconnecting when performing service. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. Service should only be performed by a qualified service agent using proper test equipment. Altering the water heater controls and/or wiring in any way could result in permanent damage to the controls or water heater and is not covered under the limited warranty. Altering the water heater controls and/or wiring in any way could result in altering the ignition sequence allowing gas to flow to the main burner before the hot surface igniter is at ignition temperature causing delayed ignition which can cause a fire or explosion. Any bypass or alteration of the water heater controls and/or wiring will result in voiding the appliance warranty. Failure to follow these instructions can result in personal injury or death. 5 INTRODUCTION @ ;" 6 6 +; ; ; 6 6 C 6" " ABBREVIATIONS USED 6 C B 6 ;; ; #)C_;#)C )B(_;)B( WB_WB #(!_#(! #V_#V J/_J/ !)_!) ; V !;%; J 6 ; ) C ! ^ ; ; ; X ;6 6:6" 6 ; ` )6 QUALIFICATIONS QUALIFIED INSTALLER OR SERVICE AGENCY C 6 ] ] 6 ` < #)C >66C ;" "6" ] ;6 NOTE: ! 6 ; ~ ^ ;#6 ; ANSI Z223.1 2006 Sec. 3.3.83: ` _ 6 ";"; 6<> " ; <> """6 ] ;} ; ] ; ] ; 6X $ ; ; ; 6X 6 X ] ; " C " ; ; #V W !"#)C~~$&*#V8#( !" #V % !#*!)_^&8'&" # W C ! !) !~~&" !
