DELIMING SOLVENTS

State Water Heaters recommends the use of UN•LIME for deliming. UN•LIME is a patented food grade acid which is safe to handle and does not create the harmful fumes which are associated with other products.

UN•LIME may be obtained from your dealer or distributor. Order Part Number 4763, 1 gallon, packed 4 gallons per case or Part Number 4813, 5 gallon container.

NOTE: Un•Lime is not available for use in Canada

Hydrochloric base acids are not recommended for use on glass lined tanks.

CAUTION

Observe handling instructions on label of product being used.

TANK CLEANOUT PROCEDURE

The following practices will ensure longer life and enable the unit to operate at its designed efficiency:

1.Once a month the heater should be flushed. Open the drain valve and allow two gallons of water to drain from the heater. Inlet water valve should remain open to maintain pressure in tank.

2.A cleanout opening is provided for periodic cleaning of the tank. Gas must be shut off and heater drained before opening cleanout.

To clean heater through cleanout opening, proceed as follows:

1.Drain heater.

2.Remove outer cover plate from lower side of heater jacket.

3.Remove six (6) hex head screws securing tank cleanout plate and remove plate.

4.Remove lime, scale, or sediment using care not to damage the glass lining.

5.Inspect cleanout plate gasket, if new gasket is required, replace with part no. 99038.

6.Install cleanout plate. Be sure to draw plate up tight by tightening screws securely.

7.Replace outer jacket cover plate.

In some water areas the sediment might not be removed by this method and may result in the water heater making rumbling or boiling noises. To dissolve and remove these more stubborn mineral deposits, UN•LIME Professional Delimer should be used.

DELIMING USING FLO-JUG METHOD

UN•LIME in the 5 gallon size is recommended for deliming. UN•LIME with the necessary hoses and fittings to delime your heater is also available as a kit: Up-N-Down Transfer Kit. Contact your local State dealer, distributor or, State Water Heaters:

Prepare the Water Heater

To delime the water heater using the Flo-Jug method, first prepare the heater for deliming as described in the "Why? When? and How?" booklet, Form No. 4800. Then install the long plastic male adapter fitting into the drain valve opening of the water heater. Use teflon tape and hand tighten only. Do not overtighten.

Prepare the Up-N-Down Transfer Kit

The next step is the preparation on the Up-N-Down Transfer Kit, if you have not already done so:

1.With the 5 gallon Up-N-Down container in the vertical position, unscrew the plastic vent cap in the handle and pierce the plastic membrane over the vent boss under the cap to allow the container to vent.

Note: If your container does not have the vent cap and vent boss, drill a 3/16" hole in the handle. When you have finished deliming you will be able to plug this drilled vent with the stainless steel screw that is supplied with the kit.

2.Remove the container's cap and cut the plastic membrane located in the 3/4" IPT opening in the cap. Take care to not damage the threads.

3.Find the 3/4" male adapter, apply teflon tape to the threaded end and screw it into the 3/4" IPT opening in the cap.

4.Put cap with male adapter back on the container and slide 3/4" hose over end of male adapter and fasten in place using hose clamp provided.

Delime using Flo-Jug Method

5.Slide the hose clamp over end of hose and slide hose over the male adapter in the water heater drain opening and secure in place using hose clamp.

6.Lift container to the "Pour" Position, see Figure 15, being careful to keep the vent in the handle above the liquid level and pour the UN•LIME into the heater.
