WARNING
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4”
TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE
THE MANUFACTURER FROM ANY CLAIM, WHICH MIGHT RESULT
FROM EXCESSIVE TEMPERATURES AND PRESSURES.
If this water heater is installed in a closed water supply system, such as the
one having a back-flow preventer in the cold water supply, provisions must
be made to control thermal expansion. DO NOT operate this water heater in
a closed system without provisions for controlling thermal expansion. Your
water supplier or local plumbing inspector should be contacted on how to
control this situation
After installation of the water lines, open the main water supply valve and fill
the water heater. While the water heater is filling, open several hot water
faucets to allow air to escape from the water system. When a steady stream
of water flows through the faucets, close them and check all water
connections for possible leaks. NEVER OPERATE THE WATER HEATER
WITHOUT FIRST BEING CERTAIN IT IS FILLED WITH WATER.
WARNING
Hydrogen gas can be produced in an operating water heater that
has not had water drawn from the tank for a long period of time
(generally two (2) weeks or more). Hydrogen gas is extremely
flammable. To prevent the possibility of injury under these
conditions, we recommend the hot water faucet to be open for
several minutes at the kitchen sink before you use any electrical
appliance that is connected to the hot water system. If hydrogen is
present, there will be an unusual sound such as air escaping
through the pipes as hot water begins to flow. Do not smoke or
have open flame near the faucet at the time it is open.
This water heater can deliver scalding temperature water at any faucet in the
system. Be careful whenever using hot water to avoid scalding injury.
Certain appliances such as dishwashers and automatic clothing washers
may require increased temperature water. By setting the thermostat on this
water heater to obtain the increased temperature water required by these
appliances, you may create the potential for scald injury. To protect against
injury, you should install an ASSE approved mixing valve in the water
system. This valve will reduce point of discharge temperature by mixing cold
and hot water in branch supply lines. Such valves are available from the
manufacturer of this water heater or a local
plumbing supplier. Please
consult with a plumbing professional.
