MAINTENANCE
The following maintenance should be performed by a qualified service technician
at the minimum periodic intervals suggested below. In some installations, the
maintenance interval may be more frequent depending on the amount of use
and the operating conditions of the water heater. Regular inspection and
maintenance of the water heater and vent-air intake system will help to ensure
safe and reliable operation.
1. Annually check the operation of the thermostat.
2. The flow of combustion and ventilation air MUST NOT be restricted. Clear
the combustion air openings of any dirt, dust, or other restrictions. WARNING!
The ventilation air system may be HOT.
3. At all times keep the water heater area clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
4. Bi-annually conduct a visual check of the main and pilot burner flames to
determine that they are burning properly. See Burner Flame Check section
on
page 12. If sooting or other burner anomalies are evident, shut down
the water heater by turning off the gas per the instructions listed in this
manual or as listed on the water heater.
5. 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.
NOTE: It is imperative for proper operation of
the water heater that the inner door be replaced in the original location.
7. At least once a year, check the combination temperature and pressure
relief valve to ensure that the valve has not become encrusted with lime.
Lift the lever at the top of the valve several times until the valve seats
properly without leaking and operates freely.
8. Monthly drain off a gallon of water to remove silt and sediment.
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 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.
11. The induced draft blower has sealed motor bearings and does not require
adding oil.
Contact your supplier or plumbing professional for replacement parts or contact
the company at the address given on the rating plate of the water heater.
Provide the part name, model and serial numbers of the water heater when
ordering parts.

qualified service technician for damaged components and/or joints
not sealed. DO NOT operate this water heater if any part is found
damaged or if any joint is found not sealed.
WARNING

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.
