WARNING: Indicates the presence of hazards or unsafe practices which could cause severe personal injury, death or substantial property damage if ignored. CAUTION: Indicates the presence of hazards or unsafe practices which could cause minor personal injury or product or property damage if ignored. NOTE: Indicates special instructions on installation, operation, or maintenance which are important but not related to personal injury hazards. WARNING—CALIFORNIA PROPOSITION 65: This product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. NOTE: These instructions are provided to ensure the proper installation and operation of Raypak boilers. Should questions arise regarding the specifications, installation, operation or servicing of these boilers, we suggest that the local Sales representative or the factory be consulted. WARNING: This unit contains refractory ceramic fiber (RCF) insulation in the combustion chamber. RCF, as manufactured, does not contain respirable crystalline silica. However, following sustained exposure to very high temperatures (>2192F), the RCF can transform into crystalline silica (cristabolite). The International Agency for Research on Cancer (IARC) has classified the inhalation of crystalline silica (cristabolite) as carcinogenic to humans. When removing the burners or heat exchangers, take precautions to avoid creating airborne dust and avoid inhaling airborne fibers. When cleaning spills, use wet sweeping or High Efficiency Particulate Air (HEPA) filtered vacuum to minimize airborne dust. Use feasible engineering controls such as local exhaust ventilation or dust collecting systems to minimize airborne dust. Wear appropriate personal protective equipment including gloves, safety glasses with side shields, and appropriate NIOSH certified respiratory protection, to avoid inhalation of airborne dust and airborne fiber particles. WARNING: To minimize the possibility of improper operation, serious personal injury, fire, or damage to the heater: • Always keep the area around the heater free of combustible materials, gasoline, and other flam- mable liquids and vapors. • Heater should never be covered or have any blockage to the flow of fresh air to the heater. WARNING: Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect the heater and to replace any part of the control system and any gas control which has been under water. WARNING: Should overheating occur or the gas supply valve fail to shut, do not turn off or disconnect the electrical supply to the heater. Instead, shut off the gas supply at a location external to the heater. DANGER: Make sure the gas on which the heater will operate is the same type as that specified on the heater rating plate. 4 RECEIVING EQUIPMENT On receipt of your equipment, visually check for external damage to the carton.
