WARNINGS — Pay Attention to These Terms

DANGER:

Indicates the presence of immediate hazards which will cause severe

 

personal injury, death or substantial property damage if ignored.

 

 

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.

 

 

 

DANGER: Make sure the gas on which the heater will operate is the same type as that specified on the heater rating plate.

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.

WARNING: Risk of electrical shock. More than one disconnect switch may be required to deenergize the equipment before servicing.

WARNING - CALIFORNIA PROPOSITION

65:This product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.

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 flammable 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.

CAUTION: Operation of this heater in low- temperature systems requires special piping. Harmful internal condensation will occur if the inlet water temperature does not exceed 105°F. Warranty claims will be denied when condensation occurs.

CAUTION: If this heater is to be installed above radiation level, it must be provided with a low water cut-off device at the time of heater installation.

CAUTION: If this heater is to be installed in a negative or positive pressure equipment room, there are special installation requirements. Consult factory for details.

CAUTION: This heater requires forced water circulation when the burner is operating. See minimum and maximum flow rates. Severe damage will occur if the heater is operated without proper water flow circulation.
