Check boiler relief valve

1.Inspect the relief valve and lift the lever to verify flow as in the following warnings, excerpted from a relief valve manufacturer’s warning label. Before operating any relief valve, ensure that it is piped with its discharge in a safe area to avoid severe scald potential. Read manual section 3, page 12, before proceeding further.

Safety relief valves should be reinspected AT LEAST ONCE EVERY THREE YEARS, by a licensed plumbing contractor or authorized inspection agency, to ensure that the product has not been affected by corrosive water conditions and to ensure that the valve and discharge line have not been altered or tampered with illegally. Certain naturally occurring conditions may corrode the valve or its components over time, rendering the valve inoperative. Such conditions are not detectable unless the valve and its components are physically removed and inspected. This inspection must only be conducted by a plumbing contractor or authorized inspection agency — not by the owner.Failure to reinspect the boiler relief valve as directed could result in unsafe pressure buildup, which can result in severe personal injury, death or substantial property damage.

Following installation, the valve lever must be operated AT LEAST ONCE A YEAR to ensure that waterways are clear. Certain naturally occurring mineral deposits may adhere to the valve, rendering it inoperative. When manually operating the lever, water will discharge and precautions must be taken to avoid contact with hot water and to avoid water damage. Before operating lever, check to see that a discharge line is connected to this valve directing the flow of hot water from the valve to a proper place of disposal. Otherwise severe personal injury may result. If no water flows, valve is inoperative. Shut down boiler until a new relief valve has been installed.

2.After following the above warning directions, if the relief valve weeps or will not seat properly, replace the relief valve. Ensure that the reason for relief valve weeping is the valve and not over-pressurization of the system due to expansion tank waterlogging or undersizing.

Inspect ignition electrode

1.Remove the ignition electrode from the boiler heat exchanger access cover.

2.Remove any white oxides accumulated on the ignition electrode using sandpaper. If the ignition electrode cannot be cleaned satisfactorily, replace ignitor with a new one.

3.Replace ignition electrode, making sure gasket is in good condition and correctly positioned.

4.Make sure the electrodes are parallel to each other.

Check ignition ground wiring

1.Inspect boiler ground wire from heat exchanger access cover to ground terminal strip.

2.Verify all wiring is in good condition and securely attached.

3.Check ground continuity of wiring using continuity meter.

4.Replace ground wires if ground continuity is not satisfactory.

Check all boiler wiring

1.Inspect all boiler wiring, making sure wires are in good condition and securely attached.

Check control settings

1.Set the control module display to Parameter mode and check all settings.Adjust settings if necessary. See Ultra Control Supplement for details.

2.Check settings of external limit controls (if any) and adjust if necessary.
