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.
WARNING! THIS WATER MAY BE HOT.
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.
