runs freely). Make certain that the heater is completely full of water

before restoring power.

Periodically (At least twice a year)

Check around the water heater and related plumbing for leaks. If

the combination temperature and pressure relief valve discharges

periodically, or water is leaking from around the heating elements,

there may be a problem with your water system. DO NOT ATTEMPT

TO REPAIR LEAKS YOURSELF! Contact a qualified service contractor

for assistance.

Check the area around the water heater for flammable liquids or

combustible materials. If any are found, remove from the area.

Vacation (Extended shut-off periods)

During extended mild or warm weather periods when hot water will

not be in use, shut off the electric power to the tank. When hot water

is needed again, restore power to the water heater.

During extended cold weather periods when hot water will not be

in use and prone to freezing conditions, shut off electric power to

the tank, close the supply line shut-off valve, open the drain valve

and drain the water heater to a safe drainage location (as detailed

previously). Once drained, close the drain valve. When hot water is

needed again, restore the water supply to the tank. Once the tank is

full, restore power.

Water drained from the water heater may be scalding hot. Take

care to avoid scalding. Wear gloves and safety glasses, and direct

water to a safe drainage location. It is recommended to turn

power off to the water heater and run water at a hot water faucet

until it cools BEFORE draining water from the heater. Failure to

comply with this warning could result in property damage, severe

personal injury, or death.

The maintenance activities described below are only to be

performed by the Installer / Qualified Service Provider. These

maintenance items should be performed during recommended

annual service and any service calls.

1. Ask the owner / user if there have been any issues with the water

heater. Diagnose any heater issues and repair / replace parts as

necessary.

2. Check the water heater and related plumbing for leaks. Repair any

that are found.

3. Check the area around the water heater for flammable liquids or

combustible materials. If any are found, remove from the area.

4. Check the heating elements while the heater is in operation. If

the elements are hissing / singing excessively, they may need to be

cleaned. Inspect the elements and clean if necessary.

5. Inspect the Temperature and Pressure (T&P) Relief Valve. See

instructions below.

6. Turn power supply off to the water heater. Open the drain valve

and drain a few gallons of water from the tank to clear any hard

water deposits. Once complete, close the drain valve and restore

power to the water heater.

T&P Relief Valve Maintenance Instructions:

•

Annually: Certain naturally occuring mineral deposits may

adhere to the valve, blocking waterways and rendering the

valve inoperative. The T&P Relief Valve lever must be operated

to ensure the waterways are clear. If waterways are clear, hot

water will discharge from the valve. Take precautions to avoid

personal injury and property damage from contact with hot

water. Before operating lever, check to see that a discharge

line is connected to the valve, directing the flow of hot water

from the valve to a proper place of disposal.

•

Replacement of the valve is required if no water flows when

the lever is operated. Turn the water heater off until the valve

is replaced.

•

If water flows from the valve, drain a few gallons from the tank

to ensure the water flows freely.

•

At least once every three years: To ensure that the T&P

valve has not been affected by corrosive water conditions

and that the valve and discharge line have not been altered

or tampered with illegally, relief valves should be inspected,

and replaced, if necessary, by a licensed plumbing contractor

or qualified service technician.

Failure to comply with these guidelines could result in failure

of relief valve operation, and possibly result in substantial

property damage, severe personal injury, or death.
