Tank (Sediment) Cleaning Burner Inspection
Sediment build-up on the tank bottom may create varying
amounts of noise, and if left in the tank will cause premature
tank failure. In some water areas, you may not be able to drain
all sediment deposits by simply draining the tank. In these cases
Mag Erad (part no. 23600) can be used to help remove the sedi-
ment deposits. This may be ordered from the Sears Service
Center. For ordering, refer to the "Parts Order List" section.
