General Information continued-
SACRIFICIAL ANODES—Three sacrificial anode rods have been
installed in the tank head to extend tank life. The anode rods should be
inspected annually to determine the amount of sacrificial decay and replaced
when necessary to prolong tank life. Water conditions in your area will
influence the time interval for inspection and replacement of the anode rod.
The use of a water softener may increase the speed of anode consumption.
More frequent inspection of the anode is needed when using softened (or
phosphate treated) water. Contact the plumbing professional who installed
the water heater or the manufacturer, listed on the rating plate, for anode
replacement information.
WARNING
Install a discharge line so that water discharged from the temperature
and pressure relief valve will exit within six (6) inches above, or any
distance below, the structural floor and cannot contact any live electrical
part. The discharge line is to be installed to allow for complete drainage
of both the temperature and pressure relief valve and the discharge line.
The discharge opening must not be subjected to blockage or freezing.
DO NOT thread, plug, or cap the discharge line. It is recommended
that a minimum clearance of four (4) inches be provided on the side of
the water heater for servicing and maintenance of the combination
temperature and pressure relief valve
Do not place a valve between the combination temperature and
pressure relief valve and the tank!
