GE Powervent AP13787 - Manual (Page 23)

DANGER: Hotter water
increases the Potential
for Hot Water SCALDS.
Households with small
children, disabled, or elderly
persons may require a 120°F
or lower gas control
(thermostat) 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 dial 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.
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. (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 it is completely
filled with water.
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 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.
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.

Operating Procedure
This heater is equipped with a spark ignitor
to light the main burner. There is no pilot
light to be lit, but on initial start-up, it is
recommended that the outer door be
removed (leave inner door in place for safety)
to determine if the spark ignitor and main
burner are operating properly.
To put the heater into operation it is only
necessary to turn the main manual gas valve
to the “ON” position, plug the power cord in
and make sure the “ON/OFF” switch located
on the blower assembly is in the “ON”
position. Within 90 seconds the spark ignitor
should spark, then the gas valve should open
and the main burner ignite. 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.”
TO SHUT OFF WATER HEATER – Turn
switch on the blower assembly to the “OFF”
position and turn the main manual gas shut-
off valve to the “OFF” position.
