• Replace relief valve, removed for deliming.
• Restore oil, water and electrical supply to heater.
• Check for water leakage.
10. Flo-Jug Cleanup.
• Allow scale to separate from UN•LIME® and settle on bottom of
Flo-Jug.
• Pour off UN•LIME® into plastic container and check for reuse.
• Rinse sediment from Flo-Jug.
• If UN•LIME® is reusable , pour back into Flo-Jug. Be sure to plug
vent and cap opening.
CIRCULATING PUMP
The water heater or water heating system may include a circulating pump.
Where used, it may need to be lubricated once every four months with
SAE No. 20 non-detergent motor oil or as directed by the manufacturer.
• Place 2 or 3 teaspoons in the bearing oil cup and 10 to 12 drops in the
motor oil cups.
SOOT REMOVAL
Soot must be removed semi-annually from the heater and flow passages
to insure efficient operation of the heater.
A TYPICAL HEATER FLUEWAY AND FLUE BAFFLE
FIGURE 20.
1. Remove chimney connector and top cover of heater from heater.
Clean out all soot deposits from connector and chimney opening. A
wire brush is recommended for this operation.
2. Remove flue baffles by lifting from tank.
3. Using a wire brush, remove soot from flue passages in heater
tank.
CAUTION: While cleaning tank flue passages, care must be taken that
brush does not come in contact with the top of the combustion
chamber as damage could occur to the combustion chamber
lining.
4. Remove oil burner assembly and using a vacuum cleaner,
remove all loose soot from combustion chamber area. Avoid
contact with combustion chamber as it can be damaged quite
easily.
• If flange gasket is damaged, replace with State Part No. 24165
5. Upon completion of cleaning, reassemble the heater. (It may be
necessary to apply new sealer tape to the top cover to ensure
proper venting. New sealer tape can be ordered from State Water
Heaters).
6. Return the heater to operation by following the start-up instructions on
page 9.
VENT SYSTEM
Examine the vent system every six months for obstructions and/or
deterioration of vent piping. Remove any soot or obstructions and replace
damaged vent piping.
ANODE ROD INSPECTION
The anode rod is used to protect the tank from corrosion. Most hot
water tanks are equipped with an anode rod. The submerged rod
sacrifices itself to protect the tank. Instead of corroding the tank,
water ions attack and eat away the anode rod. This does not effect
the water's taste or color. The rod must be maintained to keep the
tank in operating condition.
Anode rod deterioration depends on water conductivity, not
necessarily water condition. A corroded or pitted anode rod indicates
high water conductivity and should be checked and/or replaced more
often than an anode rod that appears to be intact. Replacement
of a depleted anode rod can extend the life of your water heater.
Inspection should be conducted by a qualified technician, and at
a minimum should be checked annually after the warranty period.
