DANGER
•Water temperature over 125˚F can cause severe burns instantly or
death from scalds.
•Children, disabled and elderly are at highest risk of being scalded.
•Set the thermostat as low as practical. Settings the thermostat as
low as possible will reduce the risk of scalding and reduce energy
consumption.
•Feel water before showering or bathing.
•Special valves are available to provide anti-scald protection.
Consult a licensed plumber or the local pluming authority for more
information.
If the temperature and pressure relief valve on the SB tank opens
periodically, it may be due to thermal expansion in a closed water supply
system. Consult a licensed plumber, the local plumbing authority, or the
water supplier. Do not plug the Temperature and Pressure Relief Valve.
SB TANK PIPING WITH A “MIXING VALVE”
Usually, the maximum temperature of the outlet water will stay near
the setting of the thermostat. In some cases, however, hot water usage
patterns can cause the outlet water temperature to rise significantly
above the control settings.
The temperature of water going to the fixtures may be more
carefully controlled through the use of a mixing valve. This device blends
a controlled amount of cold water with the hot water from the tank to
provide a more constant temperature at the fixtures.

WARNING
There are no user serviceable parts on this product. Attempts to service
this product by someone other then a licensed plumber or heating
technician could void the warranty, cause property damage, personal
injury or loss of life.
A mixing valve does not eliminate the risk of scalding:
•Set the thermostat as low as practical.
•Feel water before bathing or showering.
•If anti-scald or anti-chill protection is required, use devices
specifically designed for such service. Install these devices in
accordance with their manufacturer’s instructions.
Install a new Temperature and Pressure Relief (“T & P”) Valve in the
tapping on the top of the tank marked “T&P VALVE”. Failure to do so
could result in property damage, personal injury or death.
•This Valve must comply with the Standard for Relief Valves and
Automatic Gas Shutoff devices for Hot Water Supply Systems (ANSI
Z21.22)
•No valve is to be placed between the T&P valve and the tank.
•Do not install valves, reducing couplings or other obstructions in the
relief valve discharge line.
•Do not install a T&P valve with a pressure settings in excess of 150 PSI
or a temperature setting in excess of 210˚F
•Pipe the discharge line to a location where hot water discharge will
not cause injury or damage.
•Do not run any portion of the discharge line through a location that
will be exposed to freezing temperatures.
•Pipe he discharge line to allow complete drainage of both the
discharge piping and the T&P valve.
Hydrogen gas can be produced in a hot water system that has not been
used for a long period of time (generally two weeks or more). Hydrogen
gas is extremely flammable. To prevent the possibility of injury under these
conditions, it is recommended that the hot water faucet be opened for
several minutes at the kitchen sink before you use any electrical
appliance, which is connected to the hot water system. If hydrogen is
present, there will probably be an unusual sound such as air escaping
through the pipe as hot water begins to flow. There should be no smoking
or open flame near the faucet at the time it is open.

I. Product description
The Stiebel Eltron SB series water heaters are indirectly fired designed to
generate hot water in conjunction with a solar collector system or a gas,
oil or pellet boiler using forced boiler water circulation. This indirect water
heater consists of an enameled steel tank in which a smooth coil is
located. A solar heated water/glycol mix or boiler water is pumped
through the heat exchanger coil and heats the water in the tank. The SB
series is not intended for use in heating any fluid other than water. It is also
not intended for use in gravity hot water heating systems.

MAINTENANCE
The SB series tank is an extremely simple device and as such requires
very little maintenance. There are, however, several items that should be
checked out on an annual or as needed basis to ensure a reliable supply
of hot water:
1) On an annual basis, remove the jacket cover over the hand hole
and make sure that the hand hole gasket is leak-tight. On the 40
and 50-gallon sizes, this hand hole is located on the top of the SB
tank and is accessed by removing the two screws holding the cover
to the top of the SB tank.
2) Make sure that the rest of the boiler and domestic water piping is
free of leaks.
3) If there is an oil-lubricated circulator in the system, make sure that it
is lubricated as called for by the circulator manufacturer.
4) The SB tank depends upon the boiler for source of heat and is
therefore only as reliable as the boiler. Make sure that the boiler is
maintained in accordance with the boiler manufacturer’s
instructions.
5) All SB tanks are equipped with a sacrificial anode rod. This anode
rod helps to protect the SB tank from corrosion. This anode rod
should be inspected periodically and replaced if more than half of
the anode has been corroded away at any point in its length. The
rate at which the anode rod will deteriorate will depend upon the
quantity and chemistry of the water passing through the tank. In
general, an annual inspection of the anode rod is appropriate.
6) On an annual basis, check the operation of the Temperature and
Pressure Relief Valve by lifting the lever on the top of the valve and
confirming that water is released.
IMPORTANT
For the anode rod to work properly it must be electrically bonded to the
SB Tank. On the SB150 and SB200, this is done with two ground wires that
bond the anode rod to the clean-out cover and the clean-out cover to
the tank.
•Whenever the anode rod or clean out cover is serviced on the
SB150 or SB200, be sure that these ground wires are reconnected.
Failure to follow these precautions could result in premature failure of the
tank.

CAUTION
Stay away from the T&P Valve discharge piping when performing this
check to avoid contact with hot water. Also make sure that water from
the discharge will not damage property before performing this test.
