IMPORTANT SAFETY INFORMATION
Water Supply Safety
DANGERS:
!
• WATER TEMPERATURE
SETTINGS – Safety and energy
conservation are factors to be
considered when selecting the
water temperature setting of a
water heater's remote control.
Water temperatures above
125°F (52°C) can cause death
or severe burns from scalding.
Be sure to read and follow
the warnings outlined on the
pictured label.
• There is a hot water scald
potential if the water
temperature is set too high.
Households with small children,
the disabled, or elderly persons
may require a 120°F (49°C) or
lower temperature setting to
prevent contact with "HOT"
water.
• Before manually operating the
relief valve, make certain no one
will be exposed to the danger
of the hot water released by
the valve. The water may be
hot enough to create a scald
hazard. The water should be
released into a suitable drain
to prevent injury or property
damage.
• Failure to perform the
recommended Routine Preventive Maintenance
can harm the proper operation of this water
heater, which can cause carbon monoxide
dangers, excessive hot water temperatures, and
other potentially hazardous conditions.
WARNINGS:
!
• IMPORTANT: DO NOT apply heat to the HOT or
COLD water connections. If sweat connections
are used, sweat tubing to adapter before fitting
adapter to the water connections on heater.
Any heat applied to the water supply fittings will
permanently damage the internal components of
the water heater.
• In case the pipe insulation is not rated for the
appropriate weather conditions, install electric
heat tracing or equivalent to prevent freezing of
the pipes. DO NOT insulate or block the drain
valve on the hot outlet fitting. If the pipes are
allowed to freeze, the water heater and the pipes
may malfunction or leak due to freezing water.
• Failure to drain the water heater as described
on Draining the Water Heater can cause serious
personal injuries from scalding and/or damage
the water heater.

HOT
BURN BURN
Water temperature over 125°F (52°C)
can cause severe burns instantly or
death from scalds.
Children, disabled and elderly are at
highest risk of being scalded.
See instruction manual before
setting temperature at water heater.
Feel water before bathing or
showering.
Temperature limiting valves are
available, see manual.

CAUTIONS:
!
• This water heater must only be
used with the following water
supply system conditions:
– With clean, potable water
free of corrosive chemicals,
sand, dirt, or other
contaminants.
– With inlet water
temperatures above 32°F
(0°C), but not exceeding
120°F (49°C).
– DO NOT reverse the hot and
cold water connections. The
water heater will not operate.
• Even when drained properly,
a small amount of water will
remain in the water heater.
In cold weather conditions,
this water can freeze. If this
happens, allow the defrost
protection on the heater at least
30 minutes to melt the frozen
water or the water heater may
not work properly.
