discharge in an area where any remaining hot water will not cause any damage or injury.

b.Open the drain valve to flush any sediment out of the bottom to the heater.

c.Shut off the cold water supply. Make sure all hot water fixtures and circulating pumps are turned off.

d.Wait for water flow from the hose to stop. Remove the anode using a socket of the appropriate size. Do not use an impact wrench.

e.Inspect and replace the anode as required. Use pipe tape or sealant when reinstalling the anode.

f.Close the drain valve. Open a hot water fixture to allow air to escape. Open the cold water supply to the heater and allow the tank to fill.

g.Check your anode and drain valve for leaks.

h.Turn the water heater electricity on for the zone containing the Single-wall Indirect.

4.Sediment (Annual, but harsh water quality may dictate more frequent service)- Depending on water conditions, a varying amount of sediment may collect in the tank. Levels requiring service are indicated by a small temperature difference in the supply and return lines (See also “Scale” below). Repeated flushing usually clears such material. As a preventive measure, water should be drawn from the tank at the drain valve until it runs clear.

5.Scale (Annual)- Hard water may cause scale to build-up on the outside of the heat exchanger coil. A water softener will prevent this problem (See also “Sediment” above).

Symptoms would be reduced recovery capacity or reduced temperature differential between boiler supply and return lines. Repeated flushing should resolve the problem.
