State Industries Heater SUF 100150

Examine the vent system every 6 months. Points of inspection are as follows:

1. Check for obstructions and/or deterioration of the intake air and/or vent piping and the intake air and vent terminations.

Replace immediately where needed.

2. The debris screens in the intake air and vent terminations should be should be cleaned of foreign material and soot.

NOTE: Do not reach inside the vent termination when the heater is in operation.

3. Check all vent system connections for leakage and repair or reseal as necessary.

4. Inspect and clean the built-in condensate trap of any debris.

It is recommended that the water heater storage tank be drained and flushed every 6 months to reduce sediment buildup. The water heater should be drained if being shut down during freezing temperatures.

To drain the water heater storage tank:

1. Turn off the electrical supply to the water heater.

2. Turn off the gas supply at the Main Gas Shutoff Valve if the water heater is going to be shut down for an extended period.

3. Ensure the cold water inlet valve is open.

4. Open a nearby hot water faucet and let the water run until the water is no longer hot.

5. Connect a hose to the water heater drain valve and terminate it to an adequate drain.

6. Close the cold water inlet valve.

Warning: This procedure requires trained personnel with PPE!

If anode rod(s) are damaged, replace them immediately.

Upload a photo of the anode rod(s) before removal

Anode rod(s) removed without disassembling the retaining nut and wire terminal?

Upload a photo of the anode rod(s) after removal

Anode rod(s) cleaned with a soft cloth?

Upload a photo of the cleaned anode rod(s)

Warning: This procedure requires trained personnel with PPE!

Is the electrical supply to the water heater turned off?

Is the outer cleanout access panel removed from the lower side of the water heater jacket?

Is the cleanout cover removed from the cleanout opening?

Is the lime, scale and/or sediment removed without damaging the glass-lining?

Is a new cleanout gasket installed if required?

Is the cleanout cover reinstalled and drawn up tight by tightening screws securely?

Is the water heater drain valve closed?

Warning: Ensure no one is in front of or around the outlet of the Temperature-Pressure Relief Valve discharge line during the test. The water may be extremely hot. Use care when operating valve as the valve may be hot.

Temperature-Pressure Relief Valve operates freely when lever is lifted several times

Did the valve completely reset and stop releasing water after manual operation?

If the valve did not reset and continues to release water, immediately close the cold water inlet to the water heater and drain the water heater.

Temperature-Pressure Relief Valve replaced with a properly rated/sized new one if needed

Does the Temperature-Pressure Relief Valve weep or discharge periodically?

Note: Excessive water pressure is the most common cause of Temperature-Pressure Relief Valve leakage. Excessive water system pressure is most often caused by 'thermal expansion' in a 'closed system.' The Temperature-Pressure Relief Valve is not intended for the constant relief of thermal expansion.

Temperature-Pressure Relief Valve leakage due to pressure build up in a closed system that does not have a thermal expansion tank installed is not covered under the limited warranty. Thermal expansion tanks must be installed on all closed water systems.

DO NOT PLUG THE TEMPERATURE-PRESSURE RELIEF VALVE OPENING. THIS CAN CAUSE PROPERTY DAMAGE, SERIOUS INJURY OR DEATH.
