Maintenance - Bradford White RE2H50S 1NCTT Series Installation/Operation Instruction Manual

Maintenance

The water heater should be inspected annually at minimum by a qualified service technician for damaged
components. Do NOT operate this water heater if any part is found damaged.
Shut off the electric power whenever the water supply to the water heater is off. Shut off the electric power and
water supply, drain the water heater completely to prevent freezing whenever the building is left unoccupied
during the cold winter months. In order to ensure efficient operation and long tank life, drain the water heater at
least once a month through the drain valve until the water runs clear. Failure to do this may result in noisy
operation and lime and sediment buildup in the bottom of the tank. Check the temperature pressure relief valve
to ensure that the valve has not become encrusted with lime. Life the lever at the top of the valve several times
until the valve seats properly without leaking and operates freely.
When lifting the temperature pressure relief valve lever, hot water will be released under pressure. Be
certain that any released water does not result in bodily injury or property damage. The magnesium anode
rod should be inspected periodically and replaced when necessary to prolong tank life.
Note: If the
temperature and pressure-relief valve on the hot water heater discharges periodically, this may be
due to thermal expansion in a closed water system. Contact the water supplier or your plumbing contractor on
how to correct this. Do not plug the relief valve outlet.
Properly maintained,
that the following yearly preventive maintenance program be established.

pressure-relief valve, located on the front-right side of the water heater, to make certain the valve
