SECTION V: OPERATION (cont.)
Hot water in excess of 120°F can cause scalding! The temperature at which injury
occurs varies with the person's age and the time of exposure. The slower response
time of disabled persons increases the hazards to them. NEVER allow small children to
use a hot water tap. NEVER leave a child or disabled person unattended in a bathtub
or shower.
Replace the foam dam insert and access cover after adjusting/inspecting the thermostat.
If the thermostat temperature setting (or anti-scald mixing valve) was adjusted, check the
water temperature at a faucet. Flow enough water through the faucet to ensure that the
faucet temperature reflects the tank temperature. Adjust the thermostat or mixing valve
setting as necessary. Adjusting the thermostat setting (lower or higher) will not
immediately affect the water temperature at the faucet. Flow a sufficient amount of water
or allow a heat-up cycle to complete before making further adjustments.
SECTION VI: MAINTENANCE
WATER PIPING
On an annual basis, all piping should be checked for leakage at joints, shut-off valves, and
unions.
T&P RELIEF VALVE
On an annual basis, the temperature and pressure relief valve should be checked for proper
operation. First, attach a drain line to the valve to direct the water discharge to an open
drain. This is very important because the temperature of the discharge could be very hot.
Second, lift the lever at the end of the valve several times. The valve should operate freely
and return to its original position properly. If water does not flow out of the valve, remove
and inspect for corrosion or obstructions. Replace with a new valve if necessary. Do not
repair the faulty valve as this may cause improper operation.
ANODE RODS
Anode rods should be inspected twice in the first year and at least yearly once a time interval
for inspection has been developed. It is recommended to check the rod(s) six months after
the heater is installed. If the anode rod had reduced in size by two-thirds of its original
diameter of 3/4" or shows signs of pitting, it is time for replacement. Take the following
steps when changing the anode rod(s):
1. Shut off water supply.
2. Open any faucet to relieve tank pressure.
3. Remove caps on water heater top; push insulation aside.
4. Use a 1 1/16" six-sided socket wrench and a breaker bar. Snap hard to break the anode
rod seal.
5. Remove rod(s) and replace with new rod(s).
6. Turn water supply back on and leave faucet open until air is out of line.
7. Turn faucet off and check that new rod(s) doesn't leak.
8. Snap caps back into place.
