ATTENTION USER!

Have the water heater serviced at least once an- nually by a qualified service technician.

Follow the maintenance procedures below at least monthly.

Read “Water heater temperature adjustment,” page 24.

Failure to comply with the above can result in severe personal injury, death or substantial property dam- age.

MONTHLY maintenance by user

At least MONTHLY, visually check valves, pipes and fittings for leaks.

Check hot water supply at several outlets. Make sure water temperature is not too hot.

Call qualified service technician to repair leaks or address problems.

MONTHLY maintenance by user

At least MONTHLY, visually check valves, pipes and fittings for leaks.

Check hot water supply at several outlets. Make sure water temperature is not too hot.

Call qualified service technician to repair leaks or address problems.

ANNUAL start-up by qualified service technician

Obtain an Inspection and service kit (see“Replacement parts,” page 39) before attempting to perform the annual start-up. This kit contains items that will usually have to be replaced.

Check water supply temperature at several outlets to ensure the water temperature is acceptable for intended use and that all temperature control devices are functioning properly. Read page 3 and verify that all requirements are met by the installation.

Part number GL-E223-ADOC 0311

Plugging T&P relief valve or dis- charge piping can cause excessive pressure in the water heater, result- ing in severe personal injury, death or substantial property damage.

Perform the following procedures:

❏❏Perform any procedures required by local codes.

❏❏Verify system pressure both on domestic water and boiler water sides.

❏❏Manually operate T&P relief valve at least once a year (see Figure 21). This will release some hot water. Move operating lever to open position for a few seconds and then move it back, allowing it to snap closed. After T&P relief valve is operated, if it continues to release water, close cold water inlet to water heater immediately. Follow draining instructions, and replace the T&P relief valve. If T&P relief valve weeps periodically, it may be due to thermal expansion. Install an expansion tank if not already installed.

❏❏Follow instructions on circulator to oil it, if oil- lubricated.

❏❏Follow instructions in “Inspect anode and water heater interior,” page 26.

❏❏Check valves, pipes and fittings for leaks.

❏❏Check function of all controls and valves (see con- trol manufacturer’s instructions).

❏❏Review homeowner’s maintenance responsibilities
