Water Temperature; Operating The Water Heater - Rheem GG50T06PVT Use And Care Manual

Operating the water heater.

CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that
has not been used for a long period of time (generally two weeks or more). HYDROGEN GAS IS
EXTREMELY FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that
the hot water faucet be opened for several minutes at the kitchen sink before using any electrical
appliance connected to the hot water system. If hydrogen is present, there will be an unusual sound
such as air escaping through the pipe as the water begins to flow. Do not smoke or use an open flame
near the faucet at the time it is open.

setting to prevent
contact with HOT water.
Operating Procedure
This heater is equipped with an electronically
lit pilot to light the main burner. The pilot
is automatically lit each time there is a
demand for heating the water. On initial
start-up, it is recommended that the outer
door be removed (leave inner door in place
for safety) to determine if the pilot and
main burner are operating properly.
Once filled with water, it is necessary to plug
the power cord in and make sure the "ON/
OFF" switch located on the blower assembly
is in the "ON" position and the gas control
switch is in the "ON" position. The blower will
Water Temperature Setting
The temperature of the water in the water
heater can be regulated by pressing the
button on the front of the gas control
(thermostat).
Safety and energy conservation
are factors to be considered when
selecting the water temperature
setting of the water heater's gas
control (thermostat(s)). The lower the
temperature setting, the greater the
savings in energy and operating costs.
To comply with safety regulations, the
gas control (thermostat) was set at
its lowest setting before the water
heater was shipped from the factory. The
recommended starting point temperature
is 120°F.

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 burners, 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
section, it is recommended that a qualified person or
serviceman perform the work.
start and within seconds the pilot will light
followed by the main burner. After the main
burner ignites, replace the outer door.
If no main burner flame is established, the
gas control will go through three trials
for ignition before going into a lock-out.
A warning light will alert the user of this
lock-out condition. If this happens, refer to
"Troubleshooting Guide."
Water temperatures above 125°F
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 near
the gas control thermostat.
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.
