Anode Rod Inspection
Property
Damage
Hazard
• Avoid water heater damage.
• Inspection and replacement of anode as needed.
Each water heater contains at least one anode rod, which will
slowly deplete (due to electrolysis), prolonging the life of the water
heater by protecting the glass-lined tank from corrosion. Adverse
water quality, hotter water temperatures,
high hot water usage,
hydronic heating devices, and water
softening methods can increase the
rate of anode rod depletion. Once
the anode rod is depleted, the tank
wilt start
to corrode,
eventually
developing a leak.

and the water. The most common
ROD
complaint associated with the anode
rod is a "rotten egg smell" produced
from the presence
of hydrogen
sulfide gas dissolved
in the water.
IMPORTANT:
Do not remove this
anode rod permanently
as it will

eliminate water odor problems.
The
water supply system may require special filtration equipment
from a water conditioning company to successfully eliminate all
water odor problems.
Artificially softened water is exceedingly corrosive because the
process substitutes sodium ions for magnesium and calcium ions.
The anode rod should be inspected after a maximum of three
years and annually thereafter until the condition of the anode
rod dictates its replacement.
NOTE: Artificially softened water
requires the anode rod to be inspected annually.
The following are typical (but not all) signs of a depleted anode rod:
• The majority of the anode rod's diameter is tess than 3/8".
•
Significant sections of the support wire (approx. 1/3 or more
of the anode rod's length) are visible.
If the anode rod show signs of either or both it should be replaced.
NOTE: Whether re-installing or replacing the anode rod, check for
any leaks and immediately correct if found. In replacing the anode:
1. Turn off power to the water heater.
2. Shut off the water supply and open a nearby hot water faucet
to depressurize the water tank.
3. Drain approximately 5 gallons of water from tank.
(Refer to
"Draining and Flushing" for proper procedures). Close drain valve.
4. Remove old anode rod.
5. Use Teflon® tape or approved pipe sealant on threads and
install new anode rod.
6. Turn on water supply and open a nearby hot water faucet
to purge air from water system.
Check for any leaks and
immediately correct any if found.
7. Restart the water heater as directed in this manual. See the
Repair Parts Illustration for anode rod location.

Temperature-Pressure
Relief Valve Operation
The temperature-pressure
relief valve must be manually operated
at least once a year.
• Burn hazard
• Hotwater discharge.
• Keep clear
of relief valve
discharge outlet.
The temperature-pressure
relief valve must be manually operated
at least once a year. Caution should be taken to ensure that
(1) no one is in front of or around the outlet of the temperature-
pressure relief valve discharge line, and (2) the water manually
discharged wilt not cause any property damage or bodily injury.
The water may be extremely hot.
