Maintenance continued-
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.
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 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 annually
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.
10. The blower has sealed motor bearings and does not require adding oil.
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
Do not run out of propane gas. Damage to the water heater may occur.
WARNING
THIS WATER MAY BE HOT.
