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

manufacturer’s instructions and applicable local codes before
putting the appliance into operation.
A
WARNING:
For appliances that allow indoor installation within
a residential living space or home, note that this product burns
gas to produce heat. The appliance must be properly installed,
operated, and maintained to avoid exposure to appreciable levels
of carbon monoxide and the installer is required to confirm that at
least one carbon monoxide alarm is installed in the living space
before the appliance is put into operation. It is important for the
carbon monoxide alarms to be installed, maintained, and replaced
following the alarm manufacturer’s instructions and applicable
local codes.
A
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.
A
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.
