SAFETY
4 • Residen al Standard Gas Water Heater Use and Care Guide
IMPORTANT SAFETY INFORMATION
T
o reduce the risk of property
damage, serious injury or death,
read and follow the precau ons below,
all labels on the water heater, and
the safety messages and instruc ons
throughout this manual.
RISKS DURING
INSTALLATION AND
MAINTENANCE
Li ing Risk
WARNING! The
water heater is heavy.
Follow these precau-
ons to reduce the
risk of property damage, injuries from
li ing or impact injuries from dropping
the water heater.
• Use at least two people to li the
water heater.
• Be sure you both have a good grip
before li ing.
• Use an appliance dolly or hand
truck to move the water heater.
Explosion Risk
WARNING! Read the water heater’s
data plate to determine the type of
gas required. Failure to follow these
instruc ons can result in serious injury
or death from explosion, fi re or
carbon monoxide poisoning.
• Do not connect a natural gas water
heater to an L.P. gas supply.
• Do not connect an L.P. gas water
heater to a natural gas supply.
• Use a new CSA approved gas
supply line.
• Install a shut-off valve on the gas
supply line.
Gas Pressure
WARNING! The gas supply pressure
must not exceed the maximum supply
pressure as stated on the water
heater’s data plate. The minimum
supply pressure is for the purpose of
input adjustment. L.P. gas supply
pressure must not exceed 13” water
column. Have a qualifi ed person
(licensed plumber, gas company
personnel, or authorized service
technician) check for proper L.P. gas
pressure. L.P. gas pressures exceeding
13” water column can result in serious
injury or death from explosion or fi re.
RISKS DURING
OPERATION
Scalding Risk
This water heater
can make water hot
enough to cause severe burns instantly,
resul ng in severe injury or death.
• Feel water before bathing or
showering.
• To reduce the risk of scalding,
install Thermosta c Mixing Valves
(temperature limi ng valves) at
each point-of-use. These valves
automa cally mix hot and cold
water to limit the temperature at
the tap. Mixing valves are available
from Lowe’s®. Follow manufac-
turer’s instruc ons for installa on
and adjustment of the valves.
• The gas control valve on this water
heater has been factory set to its
lowest se ng to reduce the risk
of scalding. Higher temperatures
increase the risk of scalding, but
even at 120°F, hot water can scald.
If you choose a higher tempera-
ture se ng, Thermosta c Mixing
Valves located at each point-of-use
are par cularly important to help
avoid scalding.
Table 1
Temperature
Time to Produce
a Serious Burn
120°F (49°C) More than 5 minutes
125°F (52°C) 1½ to 2 minutes
130°F (54°C) About 30 seconds
135°F (57°C) About 10 seconds
140°F (60°C) Less than 5 seconds
145°F (63°C) Less than 3 seconds
150°F (66°C) About 1½ seconds
155°F (68°C) About 1 second
For informa on about changing the
factory temperature se ng, refer to
the “Adjus ng the Temperature” sec-
on in this manual .
Even if you set the water heater’s gas
control valve to a low se ng, higher
water temperatures may occur in cer-
tain circumstances:
• In some cases, repeated small draws
of water can cause the hot and cold
water in the tank to “stack” in layers.
If this happens, the water can be as
much as thirty degrees ho er than
the gas control valve se ng. This
temperature varia on is the result
of your usage pa ern and is not a
malfunc on.
• Water temperature will be ho er if
someone adjusted the gas control
valve to a higher se ng.
• Problems with the gas control valve
or other malfunc ons may result in
higher than expected water tem-
peratures.
• If the water heater is in a hot envi-
ronment, the water in the tank can
become as hot as the surrounding
air, regardless of the temperature
se ng.
