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.
