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.
