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.
• Heater should never be covered or have any blockage
to the flow of fresh air to the heater.
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 [greater than 2192°F (1200°C), 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 burner or heat exchanger, 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
including gloves, safety glasses with side shields, and
appropriate NIOSH-certified
to avoid inhalation of airborne dust and airborne fiber
particles.
WARNING:
A Improper
alteration, service, or maintenance can cause property
damage, personal injury or loss of life. Installation
and service must be performed by a qualified installer,
service agency, or the gas supplier.

A WARNING: Gasoline, as well as other flammable
materials and liquids (adhesives, solvents, etc.), and
the vapors they produce, are extremely dangerous. Do
not handle, use, or store gasoline or other flammable or
combustible materials in the vicinity of a heater.
A WARNING: Both natural gas and propane have
an odorant added to aid in detecting a gas leak. Some
people may not physically be able to smell or recognize
this odorant. If you are unsure or unfamiliar with the
smell of natural gas or propane, ask your local gas
supplier. Other conditions, such as "odorant fade,"
which causes the odorant to diminish in intensity, can
also hide, camouflage, or otherwise make detecting a
gas leak by smell more difficult.
WARNING: UL-recognized fuel gas detectors are
A
recommended in all enclosed propane and natural
gas applications wherein there is a potential for an
explosive mixture of fuel gas to accumulate and their
installation should be in accordance with the detector
manufacturer's recommendations and/or local laws,
rules, regulations, or customs.
WARNING: Do not install within 3 feet (0.9 m) of
A
a heat pump or an outdoor condensing unit. Strong
air intake from this type of equipment can disturb the
combustion process and cause damage or personal
injury.
A WARNING: The heater shall not be located in an
area where water sprinklers, or other devices, may cause
water to spray through the cabinet louvers and into the
heater. This could cause internal rusting or damage
electrical components, causing damage which will not
be covered under warranty.
