CLEANOUT – All models are equipped with a cleanout opening to aid in removal of hard water deposits from the tank
bottom. If this water heater operates under hard water conditions, the following should be performed at least every 3
months: Turn off water supply and drain the water heater. Remove the cleanout jacket cover and tank cover. When
cleaning the tank, care must be taken to avoid trying to break deposits loose as this could damage the glass lining and
shorten the life of the water heater. After cleaning, re-install the cleanout tank cover and jacket cover, and refill with
water. Refer to the section, “Section X – Maintenance” in this Installation and Operating Instruction manual for the
procedures for filling and draining the water heater.
SACRIFICIAL ANODES – Four sacrificial anode rods have been installed in the tank head to extend tank life. The anode
rods should be inspected periodically for corrosion 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 rods. The use of a water softener
may increase the speed of anode consumption. More frequent inspection of the anodes is needed when using softened
(or phosphate treated) water. Contact the installing contractor, or service provider that installed the water heater or the
manufacturer listed on the rating plate for anode replacement information.
DISHWASHING MACHINE REQUIREMENTS
All dishwashing machines meeting the National Sanitation Foundation requirements are designed to operate with water
flow pressures between 15 and 25 pounds per square inch. Flow pressures above 25 pounds per square inch, or below
15 pounds per square inch, will result in improperly sanitized dishes.
The National Sanitation Foundation also recommends circulation of 180°F water. Where this is done, the circulation
should be very gentle so that it does not cause any unnecessary turbulence inside the water heater. The circulation
should be just enough to provide 180°F water at the point of take-off to the dishwashing machine. Adjust flow by means
of the valve in the circulation line.
