Maintenance (continued)-
6. 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.
7. Monthly drain off a gallon of water to remove silt and sediment.
8. 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.
9. A combination sacrificial anode rod/hot water outlet nipple has been
installed to extend tank life. The anode rod should be inspected periodically
(every 2 years) and replaced when necessary to prolong tank life. Water
conditions in your area will influence the time interval for inspection and
replacement of the anode rod. 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.
WARNING
• Do not operate water heater with jumpered, altered, loosely
tightened or absent controls and/or components.
• Do not operate water heater with replacement controls and/or
components which are not exact duplicates or original equipment.
• Thoroughly inspect and replace, (as needed) burner inner door
gasket and/or sight window gasket any time burner inner door is
removed or disturbed.
• Replace water heater if involved in flammable vapors incident.
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.
WARNING! THIS WATER MAY BE HOT.
