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 the water at a hot faucet until it cools
BEFORE draining water from the heater. Failure to comply with this warning could result in substantial property damage, severe
personal injury, or death due to scalds.
After flushing until water runs clear, operation is complete. Close drain valve and reopen supply line shut-off valve. Make certain that
heater is completely full of water before restoring power to the heater.
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. Failure to comply with this warning could result in substantial property damage, severe personal
injury, or death due to scalds.
The maintenance activities described below are only to be performed during service 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, following page.
T&P Relief Valve Maintenance Instructions:
Annually: Certain naturally occurring 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 relief valve, drain a few gallons from the tank to ensure water flows freely.
At least once every three years: To ensure that the T&P relief 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 THE ABOVE GUIDELINES COULD RESULT IN FAILURE OF RELIEF VALVE OPERATION,
RESULTING IN POSSIBILITY OF SUBSTANTIAL PROPERTY DAMAGE, SEVERE PERSONAL INJURY, OR DEATH.
