Monthly (Every two weeks in hard water locations)
It is recommended that a few quarts of water be drained from the heater. This will flush sediment deposits from the bottom of the heater
and lengthen the heater’s service life. Turn off power to the heater during flushing operation, so the element(s) will not be damaged.
Failure to shut off power to the heater when draining may damage the heating elements. Operating a partially filled/empty water heater
could lead to damage from “dry-firing”. Failures due to such damage are NOT covered by warranty.
To flush the tank, attach a hose to the field installed drain valve in the cold water supply line. Close supply line shut-off valve. Open
drain line valve and hot water faucet(s) to vent heater while draining. Direct the flow of water to a drain or bucket where it will not cause
damage.
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.
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 element, 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 electrical element while the heater is in operation. If the element is hissing / singing excessively, it may need to be
cleaned. Inspect the element and clean if necessary.
5. Inspect the Temperature and Pressure (T&P) Relief Valve. See instructions below.
