Maintenance continued-
6. Annually remove the inner door and main burner assembly to clean orifices
and related parts of any dirt or other foreign material. Inspect the burner
ports for obstructions or debris and clean with a wire brush as needed.
Wire brush and/or vacuum clean the combustion chamber as needed to
remove scale deposits and debris. Inspect the inner door gasket for wear
and tear and replace if necessary. NOTE: It is imperative for proper
operation of the water heater that the inner door be properly sealed.
7. At least once a year, check the combination temperature and pressure
relief valve to insure that the valve has not become encrusted with lime.
Lift the lever at the lever at the top of the valve several times until the valve
seats properly without leaking and operates freely.
WARNING
When lifting lever of the combination temperature and pressure
relief valve, hot water will be released under pressure. Be careful
that any released water does not result in bodily injury or property
damage.
8. Monthly, drain off a gallon of water to remove silt and sediment by using
the water heater’s drain valve.
9. If the combination temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion in a closed
water supply system. Contact the water supplier or local plumbing
inspector on how to correct this situation. Do not plug the combination
temperature and pressure relief valve outlet.
10. A combination sacrificial anode rod/hot water outlet nipple has been
installed to extend tank life. The anode rod should be inspected
periodically (every two years) and replaced when necessary to prolong
tank life. Contact the plumbing professional who installed the water heater
or the manufacturer listed on the rating plate for anode replacement
information. The use of a water softener may increase the speed of anode
consumption. More frequent inspection of the anode is needed when
using softened (or phosphate treated) water.
