DANGER: There is a
hot water scald potential
if the temperature is set
too high. Households with
small children, disabled, or
elderly persons may require
a 120°F (49°C) or lower
temperature setting to
prevent contact with HOT
water.

Water Temperature Setting
The temperature of the water in the water
heater can be regulated by setting the
temperature on the front of the remote
control.
Safety factors should be considered when
selecting the water temperature setting of
the water heater’s remote control.
The remote control was set at 100°F
(38°C) before the water heater was shipped
from the factory. This is the
recommended starting point.
Water temperatures above 125°F (52°C)
can cause severe burns or death from
scalding. Be sure to read and follow the
warnings outlined in this manual and on
the label located on the water heater.
Mixing valves are available for reducing
point of use water temperature by mixing
hot and cold water in branch water lines.
Contact a licensed plumber or the local
plumbing authority for further
information. (See page 4 for more details.)
The chart below may be used as a guide in
determining the proper water temperature
for your home.
Safety Precautions
Do turn off manual gas shut-off valve if water heater
has been subjected to over heating, fire, flood,
physical damage or if the gas supply fails
to shut off.
Do Not turn on water heater unless water and gas
supplies are fully opened.
Do Not turn on water heater if cold water supply
shut-off valve is closed.
Do Not allow combustible materials such as
newspaper, rags or mops to accumulate near
water heater.
Do Not store or use gasoline or other flammable
vapors and liquids, such as adhesives or paint thinner,
in vicinity of this or any other appliance.
If such flammables must be used, open doors
and windows for ventilation, and all gas burning
appliances in the vicinity should be shut off including
their pilot lights, to avoid vapors lighting.
NOTICE: Flammable vapors can be drawn by air
currents from surrounding areas to the water heater.
If there is any difficulty in understanding or following
the Operating Instructions or the Care and Cleaning
