DANGER: Make sure the gas on which the heater will
A
operate is the same type as that specified on the heater
rating plate.
A WARNING: Heaters using propane gas are different
from natural gas models. A natural gas heater will not
function safely on propane and vice versa. Conversions
of heater gas type should only be made by qualified
installers using factory supplied components. The heater
should only use the fuel type in accordance with listing
on rating plate. Any other fuel usage will result in death
or serious personal injury from fire and/or explosion.
A 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.
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.
• Heater should never be covered or have any blockage
to the flow of fresh air to the heater.
A CAUTION: This heater requires forced water
circulation when the burner is operating. See Table J
and Table L for flow rate information. Severe damage will
occur if the heater is operated without proper water flow
circulation.

WARNING: Risk of electrical shock. More than one
A
disconnect switch may be required to de-energize the
equipment before servicing.
NOTE: Minimum pipe size for the heater inlet/outlet
connections is dependent on the equivalent length of
piping between the load loop and the heater loop, the
operating conditions and the size of the heater. See
Table J and Table L.
WARNING: Both natural gas and propane have
A
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.
CAUTION: If this heater is to be installed in a negative
A
or positive pressure equipment room, there are special
installation requirements. Consult factory for details.
