MAINTENANCE

To ensure efficient and safe operation, Slant/Fin recommends
the servicing of the heater by a competent service technician.
Lime or Sediment Buildup (Every 6 months)
To reduce the buildup of lime or sediment it is recommended
that the tank be flushed every six months.
1. Drain the tank through the drain valve at the bottom of
the tank until the water is clear.
2. Inspect the tank for any deposits of lime or sediment.
3. Remove lime, scale or deposits using care not to
damage the tank lining.
Temperature & Pressure Relief Valve (Every 12 months)
1. Before manually testing theT & P valve, make sure the
valve is piped in a manner that will not cause harm or
damage any surrounding area.
2. Manually open the relief valve and allow it to flush out
any lime or sediment deposits.
3. Allow the relief valve to snap shut, making sure the seal
closes properly.

Magnesium - Anti-Corrosion Anodes (No longer than
every 12 months)
The Water Heater is provided with two magnesium anti-cor-
rosion anodes, an upper and a bottom anode.
Assessment of the condition of the bottom anode can be
made by judging the condition of the upper anode.
Removal of the anodes:
1. Shut off all power to the heater.
2. Close the domestic cold water supply valve.
3. Open the household hot water taps.
4. Attach a hose to the drain valve located at the bottom of
the heater and allow the heater to drain.
5. Unscrew the anodes. (Two shiny 1-1/4" Hex Heads on front
of tank.)
EXAMINE THE ANODES AND REPLACE IF THE DIAME-
TER IS LESS THAN .40 inches.
6. Replacement of the Anodes -- The use or P.T.F.E. tape is
recommended to ensure watertight connection of the
anodes.
Failure to inspect the anodes may result in premature
failure of the heater.
